Metal Building Insulation and Air Leakage

Architects, engineers, and specifiers are required to incorporate energy efficiency codes as they continue to change with each passing cycle. One aspect strongly reflected in the approved energy codes is the tested air leakage requirements for structures, including metal building systems. A couple of states are early adopters (California and Washington), but many states—particularly those who have adopted ASHRAE 90.1-2019 and International Energy Conservation Code (IECC) 2021—will need to get ready. Now.

In this article, we will focus on air leakage reduction, which goes back to the 2012 IECC, and how fiberglass insulation systems meet all current requirements. The air leakage provisions were developed in response to the diminishing returns of adding more mass fiberglass insulation in cavity spaces and environmental pressures from various agencies.

In 2012, the IECC introduced an air leakage component and provided three paths to compliance, each governed by a respective ASTM standard and measured at a pressure differential of 75 Pascals (1.57psf). Below are the three compliance options.

  • Materials with an air permeability no greater than 0.004 cfm/ft2
  • Assemblies of materials and components not to exceed 0.04 cfm/ft2
  • Whole building air leakage test results not to exceed 0.40 cfm/ft2

In simple terms, air leakage tests incorporate a blower door, visual inspection, and infrared pictures. In a commercial building, the test involves sealing the building, using a fan (or fans, depending on building size) to create pressure differences, and measuring air flow to detect leaks. Data from pressure differentials, visual inspections, and infrared technology identify those air leak points, now mandatory for any state adopting IECC 2021 or ASHRAE 90.1 2019.

It is important to note a key difference between IECC and ASHRAE 90.1: The IECC requires a whole building test, unless an exemption applies due to climate zone or building size; whereas ASHRAE 90.1 allows the use of an installation verification program instead of a whole building test for any building.

Figure 1 shows the progression of whole building testing requirements (ASTM E779).

Many members of NIA’s Metal Building Laminator Committee are also members of the Metal Building Manufacturers Association (MBMA) and its Air Leakage Task Force. This group, with the help of third-party experts, led air leakage tests on several newly constructed metal building systems to evaluate air leakage. These studies encompassed various climate zones, building uses, and fiberglass insulation systems. It was important to test how fiberglass insulation systems perform and ensure these products would meet the air leakage requirements.

After many tests, it was concluded that all the tested fiberglass insulation systems yielded a positive result concerning the 0.40 cfm/ft² threshold. The project highlighted the importance of and level of detail needed for the installation technique used for all materials. The studies culminated in the MBMA publication of “Best Practices to Comply with Whole Building Air Leakage Testing Requirements for Metal Building Systems.”

Many states (13) have already adopted IECC 2021/ASHRAE 90.1–2019, and it is just a matter of time before other states follow. As communicated in this article, anything after the 2012 IECC will have an air infiltration component to it. Now is the time to prepare and understand what may be required.

As members of NIA’s Metal Building Laminators Committee and suppliers of fiberglass insulation systems, we are attuned to and participate in energy efficiency and building code developments. Please reach out to us if you have questions or need to understand how air infiltration will affect your project.

Metal Building Insulation and Surface Burning Characteristics

The NIA recently released a new, updated standard for metal building insulation. It can be found on the NIA website and is officially titled, “NIA Certified Faced Insulation® Standard (Version 404.2-2024).” One of the major changes to the standard centers on the surface burning characteristics of faced metal building insulation. The goal of this article is to explain what surface burning characteristics are, how they affect the type of insulation you choose for your building, and what the new standard has done to further promote safety within the metal building construction industry.

What Are Surface Burning Characteristics, and Why Should We Care?

The surface burning characteristics of a product are more commonly referred to as its flame spread and smoke developed index. The index rating of a product is a comparative measurement of the spread of the flame and smoke obscuration versus time for the material tested, in accordance with ASTM E84 and UL 723. The ASTM E84 and UL 723 test method and classification of products came about, over time, as a result of some horrific fires that occurred within the United States, dating back to 1942.

The common theme in all three tragedies was the rapid flame progression along the surfaces of the exposed interior finish of the walls and ceilings, which ultimately led to the adoption of the ASTM E84 Standard Test for Surface Burning Characteristics of Building Materials in 1961.

Although time has passed, the need and awareness still exist today. More than 70 years after the adoption of ASTM E84, another tragedy struck in Rhode Island, in February 2003. A fire erupted and quickly spread during a performance of the metal band, Great White, at the Station nightclub in West Warwick, leaving 100 dead and 230 injured. Once again, one of the primary factors of this tragedy was the rapid flame spread on the surface of the ignited ceilings and walls (see “20 years after the Station nightclub fire, a look at what’s changed,”GBH, www.wgbh.org/news/local/2023-02-21/20-years-after-the-station-nightclub-fire-a-look-at-whats-changed).

What Do the Building Codes Require Regarding Metal Building Insulation and Surface Burning Characteristics?

The International Building Code (IBC) assigns a Surface Burning Characteristic Classification to all building products required to be tested using the ASTM E84 Standard. More specifically, Chapter 8, Interior Finishes, of the 2024 IBC, Section 803.1.2 Interior Wall and Ceiling Finish Materials Tested in Accordance with ASTM E84, are categorized into three classes, as follows:

  • Class A = Flame spread index 0–25; smoke developed index 0–450
  • Class B = Flame spread index 26–75; smoke developed index 0–450
  • Class C = Flame spread index 76–200; smoke developed index 0–450

The following building codes and standards utilize these classes to help determine which products meet code:

  • International Building Code (IBC)
  • International Mechanical Code (IMC)
  • International Fire Code (IFC)
  • Uniform Mechanical Code (UMC)
  • National Fire Protection Association (NFPA) 1 – Fire Code
  • NFPA 101 – Life Safety Code
  • NFPA 5000 – Building Construction and Safety Code
  • NFPA 90A – Standard for the Installation of Air-Conditioning and Ventilating Systems

The primary reasons to insulate a metal building, besides meeting the codes, are for thermal and acoustic/sound purposes. When determining the materials needed to insulate a metal building, one of the main resources utilized is the ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings. Per ASHRAE 90.1–2022, within metal buildings, fiberglass insulation systems can be single layer, double layer, liner system, or filled cavity. In each of these systems, the fiberglass insulation can be either faced (laminated) or unfaced.

When using a faced metal building insulation-whether in the ceiling or walls of metal buildings, or both-in the vast majority of cases, the faced side of the fiberglass insulation is left exposed to the interior of the building.

Section 720.3, Exposed Installation, states, “Insulating materials, where exposed as installed in buildings of any type of construction, shall have a flame spread index of not more than 25 and a smoke-developed index of not more than 450.”

In simple terms, both concealed and exposed faced metal building insulation must be Class A to meet the IBC.

Although not common in practice, there are instances where metal building insulation becomes incorporated into the design of the plenum. In these cases, we would refer to IMC, UMC, and NFPA 90A.

Per the IMC, Section 602.2, Construction of Plenums, states, “Plenum enclosure construction materials that are exposed to the airflow shall comply with the requirements of Section 703.3 of the International Building Code or such materials shall have a flame spread index of not more than 25 and a smoke-developed index of not more than 50 when tested in accordance with ASTM E84 or UL723.”

The UMC and NFPA 90A also state that any insulation materials exposed with a plenum must have a flame spread index of not more than 25 and a smoke-developed index of not more than 50.

Although we have mentioned the more nationally recognized codes and standards, it is important to note that prior to any construction project, it is imperative that all local municipalities’ and state code adoptions be researched and recognized. The best way to do this would be to contact your local authority having jurisdiction (AHJ).

What Does All This Have to Do with the NIA Certified Faced Insulation Standard (Version 404.2–2024)?

In order to comply with the NIA Standard, metal building insulation laminators must subscribe to third-party laboratory verification of surface burning characteristics for their faced metal building insulation products AND have their product packages marked with the label of the certifying laboratory for surface burning characteristics. This allows the building owners, installation contractors, and building code officials and inspectors the ability to easily identify whether the metal building insulation supplied meets the code requirements for surface burning characteristics. It also holds our industry accountable and further advances the reputation and commitment our members have to the safety and well-being of our clients.

Metal Building Insulation: It’s Sustainable!

Sustainable development requires an integrated approach that takes into consideration environmental concerns along with economic development.

In 1987, the United Nations Brundtland Commission defined sustainability as, “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” Today, there are almost 140 developing countries in the world seeking ways of meeting their development needs; but with the increasing threat of climate change, concrete efforts must be made to ensure development today does not negatively affect future generations.

We are in the construction business. We love seeing growth and development. But at what cost to our environment and natural resources? Focusing on using materials and systems that will help save energy and resources is a strong way to improve our world’s environment.

Recycled Materials

Manufacturing fiberglass is environmentally friendly because it is created from recycled glass—sometimes more than 50% of its raw materials are recycled. Think of glass bottles, windows, and automobile windshields thrown away in landfills. According to the North American Insulation Manufacturers Association (NAIMA), using recycled glass reduces the demand on virgin resources, saves landfill space, and diverts glass containers and slag from the solid waste stream. Since the industry’s recycling program began in 1992, NAIMA members’ facilities have diverted more than 103.5 billion pounds of recycled materials from the waste stream. Now imagine the dual benefit as that tremendous amount of discarded material is melted down and spun into fiberglass that will further improve the environment by reducing energy demands and carbon/greenhouse gas emissions while economically insulating the buildings and equipment we use every day!

Return on Investment

The cost of energy is a big concern for building owners, but what about cost to the environment? The energy consumption used in making and distributing fiberglass gives excellent returns. Another study reported by NAIMA states that “a typical pound of fiberglass and rock and slag wool insulation saves twelve times as much energy in its first year in place as the energy used to produce it.” And that is just the impact regarding the carbon footprint. Imagine what you save in energy bills over the life of the building!

Fiberglass Improvements

The manufacturers of fiberglass are committed to the future and to investing in finding better ways and greener products. Here are a few of the improvements by manufacturers that we now enjoy in our use of fiberglass insulation.

  • Engineering improvements, such as the elimination of formaldehyde from its products;
  • Refining fiberglass to make it less “itchy” and easier to handle;
  • Testing and improving the consistency of R-values and performance in limited cavity spacings;
  • Increasing the amount of recycled glass used in its creation;
  • Eliminating waste by reengineering manufacturing processes to incorporate fiberglass production scrap back into the primary production process, or to reprocess it into other products; and
  • Using compressed packaging to cut energy requirements for transportation by allowing more insulation to be shipped in each truck.

Now and into the future, we will need to economize on our use and consumption of natural resources and energy. Fiberglass is a tried-and-true performer to preserve both.

Back to Basics: R-Value and U-Value

The R-value of an insulation product is a thermal resistance rating that tells us how well a material resists heat flow. The higher the R-value, the better the insulation restricts heat transfer. Most insulation manufacturers use the ASTM C518 test to measure a material’s resistance to heat flow. Established by the American Society for Testing and Materials (ASTM), the ASTM C518 test is a standardized method that assesses the steady-state thermal transmission properties of a material using a heat flow meter apparatus. In addition to serving as an essential tool for many industries, ASTM C518 is a building code requirement for insulation.

R-values for metal building insulation range from R-8 to R-30. The most common fiberglass metal building insulation R-values include:

  • 2” (R-8, before lamination)
  • 3.4” (R-10)
  • 3.7” (R-11)
  • 4.3” (R-13)
  • 5.3” (R-13)
  • 6.3” (R-19)
  • 8.0” (R-25)
  • 9.25” (R-30)

It should be noted that thicknesses are nominal, as manufacturers produce different thicknesses to meet R-values. Commercial energy code requirements dictate the minimum R-value necessary for all new construction, additions, and alterations performed in the United States.

Once the R-value is determined, designers can use this data to better understand how a material will perform in an assembly. Heat flow through a material is driven by the temperature difference on each side of the material or assembly. Most construction types and code tables leverage the R-value table as a guide to code compliance. However, it is important to remember that the R-value table should not be mistaken as a reference for the total performance of an assembly. Metal-framed walls, wood-framed walls, and metal building walls and roofs undergo testing that determines the U-value of the entire assembly. The result of that testing can be found in the U-value table.

A U-value, also called a U-factor, measures heat transfer, or loss, through the assembly over time. While the R-value measures a single product’s ability to resist heat, the U-value measures the entire assembly’s resistance to heat transfer. The lower the U-factor, the better the insulation. Mathematically, R-values and U-values are reciprocals of one another: U-value = 1/R-value, R-value = 1/U-value. ASTM C1363 is the standard test method of U-values and includes a hot box apparatus. See Figure 1 and Figure 2.

Metal Building Insulation Special Issue: An Introduction to Fiberglass Metal Building Insulation

Metal building systems (you may call them pre-engineered metal buildings) have long been favored for their strength, durability, and cost-effectiveness. However, one crucial aspect that often goes unnoticed is the insulation system. Proper insulation is essential for reducing energy consumption, maintaining comfortable indoor temperature, and ensuring the longevity of these metal structures. Among various insulation materials, fiberglass insulation stands out as a reliable and cost-effective choice. In this comprehensive article, we will explore why fiberglass insulation remains relevant and efficient for metal building systems.

Evolution – Where It Began

The evolution of fiberglass insulation use has progressed significantly since its inception, transitioning from basic single-layer applications with low R-values to sophisticated, multilayered systems that offer enhanced thermal performance and energy efficiency. Initially, fiberglass insulation was available in the form of batts or rolls, designed to be sandwiched between framing members and the roof or wall panels. While this is still a primary method of insulating a metal building, today’s energy codes have required the development of different solutions.

Over time, advancements in manufacturing and material science have led to the development of higher density fiberglass insulation products and more efficient installation techniques. Innovations include the introduction of multilayered systems, in which the installer utilizes two layers of fiberglass to further enhance performance. Modern fiberglass insulation systems often incorporate vapor barriers, reflective coatings, and other materials to address issues such as moisture control and radiant heat transfer. These systems are designed to maintain their R-value over a wider range of temperatures and conditions, ensuring consistent performance throughout the year. Unlike the single-layer fiberglass mentioned in the previous paragraph, these systems utilize the framing cavity, filling it with fiberglass to improve thermal performance.

Code Requirements

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the International Code Council (ICC) play crucial roles in developing energy codes in the United States. ASHRAE develops standards like ASHRAE Standard 90.1, which sets minimum energy efficiency requirements for commercial buildings and large multifamily housing. This standard is continuously updated through a consensus process involving industry experts, government representatives, and other stakeholders. The ICC publishes the International Energy Conservation Code (IECC), which includes energy efficiency requirements for both residential and commercial buildings. The IECC is updated every 3 years through a public consensus process, allowing for broad participation from various stakeholders. These organizations ensure that energy codes evolve to improve energy efficiency, reduce environmental impact, and promote sustainable construction practices.

Code agencies continue to value and require the properties of fiberglass insulation as a viable solution for achieving energy efficiency goals. The great news is that fiberglass insulation systems are able to meet all current energy codes.

As states adopt new codes, you will begin to see more requirements around air infiltration. This topic is becoming more relevant with each new code cycle. You should know that fiberglass insulation systems have been put to the test and perform to the current code requirements.

Benefits

Here are some of the benefits of fiberglass insulation and why it is a practical choice for metal buildings.

  • Fiberglass insulation is budget friendly, making it an attractive option for metal building projects. Although it is budget friendly, you are not sacrificing performance.
  • Fiberglass stands out for its low installed cost per R-value. R-value measures the material’s thermal resistance.
  • With the shortage of skilled labor and escalating labor costs, fiberglass insulation could be considered “user-friendly,” with its specific product markings and the general ease of handling. Its flexibility allows it to fit into irregular spaces (allowing for a filled cavity). The flexibility and ease of handling helps minimize installation costs.
  • Its durability is almost unprecedented. Unlike some materials that are prone to absorbing moisture, fiberglass insulation remains unaffected. It does not promote mold or mildew growth, ensuring a healthier indoor environment. Properly installed fiberglass insulation can last for decades without significant degradation, underscoring its cost-effectiveness over time.

Fiberglass insulation can contribute significantly to achieving, or exceeding, energy efficiency goals. The thermal performance of fiberglass insulation effectively reduces heat transfer, keeping indoor spaces warmer in winter and cooler in summer. A metal building system’s insulating properties help maintain a consistent temperature, enhancing occupant comfort, and can lead to reduced heating and cooling costs.

Tested

Metal building insulation must be tested for a myriad of safety and performance characteristics. The American Society for Testing and Materials (ASTM) is a primary agency for the development of standards that help enhance the performance of products and foster the confidence in those products that you, as both a consumer and/or architect/engineer/specifier, buy and use.

A couple of examples are:

  • ASTM E84 is the “Standard Test Method for Surface Burning Characteristics of Building Materials.” This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions. Fiberglass by nature is noncombustible; however, when you add a facing and some sort of adhesive material, it is important to test the final produced product.
  • ASTM C991 is the “Standard Specification for Flexible Fibrous Glass Insulation for Metal Buildings.” This specification covers the classification, composition, and physical properties of flexible fibrous glass insulation for use in metal building roofs and walls.

NIA 404 Standard

NIA and its Metal Building Laminator Committee* understand the importance of safety and performance characteristics related to the products we provide the market. The committee meets regularly and recently published a revised standard, “NIA Certified Faced Insulation Standard (Version 404.2–2024).” The specifics of the standard can be found at 404.2–2024

Metal building systems continue to be a popular choice for the one- and two-story commercial and industrial construction markets, since these projects require materials that are engineered to keep pace with constantly evolving design concepts and aggressive energy codes. As a committee, we are committed to providing a fiberglass insulation solution that meets the industry safety and quality requirements, as well as the most stringent energy efficiency codes.

This issue contains articles on the various aspects of metal building insulation systems and their benefits. If you need more information or have questions on utilizing certified faced fiberglass insulation solutions on your next project, reach out to NIA and our Metal Building Laminator Committee members at membership@insulation.org.

Where Is this Water Coming From?

Walking through a mechanical room, you are surprised to find a small puddle on the floor  in front of you. “How did that get there?” you wonder, as you start looking around for the source. Something catches your eye, and you see a drop of water falling from above you. Does the roof have a leak? Did someone spill something above you?

Wait, is that pipe sweating?

Water vapor is part of the air around you, as water moves through the water cycle, and it is an important part of transferring heat and energy around the world.1 All air has some water vapor in it, meaning it is always present in the air around your mechanical systems. Given the right conditions, this water vapor will condense into a liquid and will greatly affect the performance of your system.

To determine whether the conditions will lead to condensation, knowledge of the relative humidity and dew point are key. The amount of moisture in the air can be measured by the relative humidity (sometimes abbreviated “RH”), defined as the percentage of water vapor in the air compared to the maximum amount of water vapor that air at that temperature could hold. For instance, in Las Vegas, Nevada, the most arid of the major cities in the United States, the average relative humidity is only 30%, meaning that, on average, only 30% of the maximum amount of water vapor at that temperature is held in the air. Most major U.S. cities average about 70% relative humidity. See Figure 1 for a sample.2

The dew point is the temperature at which water vapor in the air condenses into a liquid. The higher the relative humidity, the closer the dew point will be to the temperature of the air. Conversely, the lower the relative humidity, the cooler the dew point temperature is. For instance, at 68°F and 70% relative humidity, the dew point is 58°F, while at that same 68°F temperature and only 30% relative humidity, the dew point is a crisp 35°F.3

If a surface is below the dew point temperature, the air around it will cool, and the water vapor will condense into a liquid on the surface. Thus, maintaining the surfaces of below-ambient mechanical systems above the dew point temperature is paramount to controlling the formation of condensation.

Condensation: Raining Indoors

Below-ambient systems—such as chilled water, refrigeration, and cool air duct systems—are highly susceptible to the formation of condensation on their surfaces. With surface temperatures far below the average indoor dew point, these systems can quickly perspire and create enough condensation to form indoor rain.

Take, for example, the conditions in Figure 2: a 40°F chilled water pipe in a warm, humid space with relative humidity of 75%. The water vapor molecules in the 80°F air will condense into a liquid, as the surface temperature (Ts) of 40°F is far below the dew point of 72°F of the space.

This is obviously not an acceptable condition for a system, but what can be done to prevent it from happening?

Preventing Condensation: Use Insulation!

Keeping the surface temperature above the dew point, 72°F in the example, is of the utmost importance in preventing condensation. Adding insulation in the proper thickness to the system not only saves energy by preventing heat gains throughout the system, but it also raises the surface temperature above the dew point (Figure 3). However, if the insulation is porous, the water vapor can still find its way through the insulation and will condense on the cold surface of the pipe, regardless of the insulation thickness. If using a porous insulation material, a vapor retarder is necessary to prevent the water vapor from passing through the insulation and condensing.

These principles also hold true for duct systems. As air-conditioning systems not only cool the space but also remove humidity, condensation control is important with duct systems. The correct insulation thickness, with vapor retarder, if necessary, will prevent condensation formation on the duct surfaces, just like the below-ambient piping systems.

Why Is Condensation Forming, Even with Insulation?

Even after a system is insulated, condensation may still form as a result of a miscalculation or poor installation. If the mechanical system designer does not take the extreme humidity conditions of the space into account, or the system functions outside the normal design parameters, the insulation thickness will not be enough to make up for the increase in water vapor in the air, and condensation will form as the surface temperature falls below the dew point. The insulation also must be installed correctly: Any gap in insulation, or any small opening in the vapor retarder, will lead to condensation and must be sealed immediately.

In order to control condensation within a below-ambient system, an insulation material with low water vapor permeability must be chosen to prevent water vapor from passing through the material and condensing on the system. The proper thickness must be determined from the worst-case conditions in the space and can be confirmed with industry or manufacturers’ calculation tools. With the right thickness, low water vapor permeability, and proper installation, a system will be protected from the effects of condensation.

The Problem with Condensation

Condensation in a mechanical system does not just bring the nuisance of dripping water; it can also lead to devastating effects to the insulation or system itself. Moisture ingress is the absorption of water in a porous material that leads to an increase in thermal conductivity and the deterioration of the insulation system. Corrosion under insulation (CUI) can form when water gets trapped between the system and the insulation, heavily corroding the metal underneath. With the presence of water and a food source, mold is apt to follow any condensation that forms in the system.

Moisture Ingress: Soaking up Water Like a Sponge

Porous insulation materials rely on a vapor retarder to protect from water vapor accumulation. Unfortunately, these vapor retarders are not completely impenetrable and often get nicked or torn open during the regular maintenance process, or they are not completely sealed during installation due to difficult configurations or space constraints. With any gap in the vapor retarder, water vapor will start accumulating between the voids like a sponge soaking up water. For every 1% increase in moisture content in the material, a 7.5% loss in thermal value can be expected. After all the voids are filled, condensate will start to accumulate on the exterior surface of the insulation and the system itself, forming a thermal bridge with a thermal conductivity of water (4.1 Btu/(hr. °F. ft2/in) at 75°F mean
temperature). This thermal bridge causes large heat gains within the below-ambient system as the wet insulation allows heat to conduct to the system. When this occurs, the insulation that was used to prevent heat gain is now accelerating it, dropping the system efficiency precipitously. The water being held in close proximity of the system also can lead
to other issues, affecting the material you were trying to protect in the first place (see Figure 4 through Figure 6).

Corrosion Under Insulation

As alluded to earlier, one issue that can result from moisture ingress is CUI, or the formation of corrosion on the system surface when water is trapped between the surface of the system and the insulation. While CUI can form because of a system failure (leaks) or improper weather protection, it can also occur when condensation finds its way to the surface of a pipe through a break in the vapor barrier. Moisture ingress in porous materials can lead to CUI, as the insulation holds onto the water right next to the system itself, wrapping the metal with a wet covering and providing the means to form corrosion. CUI also can form if the water vapor finds a gap in the vapor barrier and proceeds to condense under the insulation. Any system that is subjected to corrosion will not operate as expected, as the metal starts degrading, and the maintenance cost of replacing the damaged system increases. Left alone long enough, this corrosion may lead to a complete failure of the system and the potential for catastrophic events.

Mold

Mold is various types of fungi that can grow on almost any surface that stays between 32°F and 120°F (optimally between 70°F and 90°F) with no air flow and that is damp with moisture.4 If condensation forms within the insulation and the insulation stays damp, it creates the perfect environment for mold growth to begin, often without any trace on the outside of the insulation. The mold can then propagate throughout the insulation and start to form on the surface, where it can travel throughout the air space and cause overall poor air quality within the space, potentially leading to allergies, rashes, and asthma attacks.

Conclusion: Do it Right the First Time

With below-ambient systems, condensation formation is always a risk. If the system is not insulated correctly, moisture ingress, CUI, and mold will soon follow the first drop of condensation. Not only will the insulation have to be replaced if the condensation formation is not identified in time, but the system piping, ductwork, or other components—along with any surrounding equipment that the condensation was dripping on—will have to be replaced as well. It is important to make sure the system is insulated with the right thickness of insulation so that the surface temperature is always above the dew point, and to use a complete vapor barrier to avoid condensation risks.

NIA Contractor Member Kerco Discusses System Design

NIA is proud of the professionalism, creativity, and artistry of our Contractor members. To celebrate the craftsmanship of NIA mechanical and industrial insulation contractors, in 2023 we unveiled the first-ever NIA Insulation Project Art Gallery Showcase and Competition. We invited all NIA insulation contractors to submit photographs and a brief description of projects representing their most creative and artistic efforts. At Fall Summit, we posted all the submissions anonymously, and attendees voted for the top three projects in terms of number of parts insulated, aesthetics, difficulty of installation, and well-installed application. As a new regular column, we will profile the projects submitted, focusing this month on Kerco, Inc. We encourage NIA Contractor members to participate in the 2024 Insulation Project Art Gallery Showcase and Competition to possibly be featured in future articles.

  • Type–Mylar Vapor Barrier
  • Brand–Childers

Project Description and Goals

The project involved insulating a refrigeration system for a new cold storage warehouse/process facility operating at below-ambient temperatures ranging from -40⁰F to 25⁰F. Pipes and equipment to be insulated run ammonia (-40⁰F and -25⁰F) and glycol (25⁰F), with temperatures on the piping schedule as follows:

  • Blast and cell freezer at -35⁰F,
  • Freezer at -10⁰F,
  • Dock at 10⁰F, and
  • Glycol at 25⁰F.

Goals of the project were to achieve energy savings by optimizing process efficiency (minimizing heat loss/gain in the system) and to control condensation. In addition, the customer sought to make the complex refrigeration system easier for maintenance personnel to work with by clearly delineating different process lines and temperatures, which offered the additional benefit of enhancing personnel safety.

Challenges

Sometimes the strengths of a project also present its greatest challenges. James Kerco, President of Kerco, Inc., has been in the commercial and industrial mechanical insulation industry for more than 45 years. He says, “The project was extremely well engineered, using colored PVC jacketing indoors to signify the temperature or type of system being insulated by color.” In the dock area, for example, colors were used to indicate the purpose of each pipe—condensate drain, hot gas line, refrigeration line, etc. (see Photo 1). If system repairs need to be made in the future, the colors will make it easy to isolate the line in question. While this simplifies things for facility maintenance personnel, it created a challenge for insulation installation: More than half a dozen colors were to be used, and the right color of jacketing needed to be applied to each pipe and piece of equipment insulated (along with the usual considerations, such as appropriate thickness, etc.).

System Design

Inside the facility, Kerco used polyisocyanurate insulation, with a mylar vapor barrier, applied to pipes and vessels. For condensation control, as well as process efficiency, Kerco personnel ensured insulation was installed at the correct thickness for the specific application, given the temperature of the individual pipes and the ambient temperature of the room where they were located. They used a staggered joint approach, with vapor barrier mastic applied to all seams and joints. Per specifications (and industry best practice), they applied vapor stops and expansion joints, and back-filled all voids with foam. MICA Plate 1-660 illustrates the approach they followed (see Figure 1). “We like to get [the MICA plate] on site to show how we will insulate and seal the pipe, and to educate the end user and the engineer,” James Kerco explains. “It is so important to insulate and seal particular types of insulation systems correctly. You miss one step, and you ruin the entire refrigeration system. The system can be completely destroyed within a year or two” because it was not insulated, or was not insulated properly. In contrast, Kerco adds, a sound insulation system will perform to expectations for so long that “by doing it correctly once, you don’t have to do it again.”

In both the process room and the engine room, pipes and vessels were color-coded using .030 PVC jacketing to indicate the temperature or type of system insulated (see Photo 2). The goal was for facility personnel to be able to walk into the engine room, for example, and know even from a distance what system/temperature each pipe or piece of equipment is.

As noted earlier, this feature presented a real test for the installation group, who had to “meet the challenge that all the PVC went on correctly on each system, making sure nothing was mislabeled,” James Kerco describes. To make sure the correct colors went on each piece insulated—while ensuring the correct insulation thickness was applied to each piping system—Kerco personnel insulated one system at a time, “working hand-in-hand with the refrigeration contractors” so everything was accurate.

Kerco also insulated exterior lines on the roof that provide service to the freezers, blast cells, and dock area (see Photo 3). They used .024 aluminum (painted white), with ¾ inch white stainless steel banding. The banding was essential. James Kerco notes, “You can’t use staples or screws in refrigeration jobs because you would violate the integrity of the vapor barrier. That’s the number one item that needs preservation. If that’s defeated, the system will fail.”

Table 1 offers an overview of insulation system components, listed by location.

The “Wow” Factor

James Kerco says that when facility personnel walked through the finished product, “Everyone was starstruck because of all the different colors—especially the refrigeration plant engineer and operating engineer for the refrigeration system.” Instead of the typical all-white system with labels indicating what ran inside each pipe, at what process temperature, “everything was color-coded, and they understood immediately what the colors meant.” In the end, while the use of color required that extra level of attention to detail during installation, the results were more than worth it in terms of immediate customer satisfaction and the long-term benefits of ease of maintenance and personnel safety.

Emphasis on Safety

James Kerco also stresses that completing a project on time, within budget, and achieving all the customer’s objectives is only part of the job. It is also vital that “we make sure all our employees go home safe at night.” In the pursuit of that mission, Kerco, Inc. is a 2023 NIA Safety Star™, awarded a Bronze Safety Excellence Award in April. As part of the company’s safety plan, in addition to attending regular general safety training and on-site project safety meetings, all Kerco field personnel are specifically trained on the equipment (e.g., forklift operation) and tasks they perform, and all are OSHA 10 certified; superintendents are OSHA 30 certified; and craftsmen and staff alike are trained in CPR. On this project, Kerco’s commitment meant that not only was the customer satisfied, but all Kerco employees were safe at the end of the day.

Project Takeaways

Many aspects of work performance contributed to the project’s success, but the takeaways listed below stand out as elements that are applicable to all insulation projects, whether new construction or upgrades.

  • Communication Is Key. While coordinating schedules among different trades often can be a challenge with new construction projects, James Kerco says that working with the general contractor/refrigeration contractor kept everything running smoothly on this job. He notes, “Communication went well. Everyone knew what had to be done, and we were able to apply the insulation quite well without interruption.”
  •  Start with a Sound Design and Install per Best Practices. A well-engineered, well-specified plan executed by well-trained, experienced personnel following industrybest practices virtually guarantees that project goals will be met or exceeded.
  • Planning Ahead Lowers Risk—and Stress. To ensure that all the materials were available in time, Kerco preordered those that typically require longer lead times, such as the white-painted jacketing used on the roof (which needed to be fabricated).
  • Strength in Numbers. This project offers a real-world example of NIA President Jack Bittner’s theme, Strength in Numbers, as Kerco coordinated with fellow NIA member Insul-Therm International, Inc. (www.insultherminc.com) for fabrication of the polyisocyanurate insulation for the pipes and fittings, which was manufactured by NIA Associate member DUNA-USA (www.dunagroup.com/usa).

Energy Savings

James Kerco observes that although insulation is often among the last products considered, it is one of the most critical parts of a project, especially when it comes to energy savings. He notes, “We’ve been the energy people since insulation began. We were at the forefront when we initially began insulating pipes. We were conserving energy from Day 1.” Now, as so many in government and industry are looking for ways to achieve sustainability, that is a message worth repeating.

Energizing Tomorrow: Waste-to-Energy Initiatives Transforming America


In a world where taking care of our environment is becoming more crucial, the United States is at a crossroads. People worldwide are coming together to tackle big issues like climate change, extending resources, and managing waste.

This article dives into why sustainability matters and how waste-to-energy (WTE) plants could be a possible solution to the U.S. waste crisis.

The Waste Crisis in America

The trash situation in the United States has become a significant issue, contributing to a global challenge. Despite being home to only 4% of the world’s population, the United States produces more than 12% of the planet’s total trash, according to Environment America.

In 2018 alone, the United States disposed of a staggering 292 million tons of municipal solid waste (MSW), as reported by the U.S. Environmental Protection Agency. That number has only increased since.

This type of waste includes materials thrown away by households, businesses, and institutions like schools and libraries. To put it in perspective, each American discards about 4.9 pounds of trash every day, accumulating to nearly 1,800 pounds of waste per person annually.

The concerning part is that a substantial portion of this waste, about 62%, either ends up in landfills or is burned in incinerators. This means that a considerable amount of our waste is not being effectively managed or repurposed, contributing to environmental challenges.

Why is this a problem? The excessive generation of trash poses several issues for the environment.

Landfills take up valuable space, leading to deforestation and habitat loss. Additionally, burning waste in incinerators releases harmful pollutants into the air, impacting air quality and contributing to climate change. The sheer volume of discarded materials also highlights a wasteful use of resources, as many items that could be reused or recycled end up being disposed of in ways that harm the planet.

Addressing the trash crisis in the United States is essential for creating a more sustainable future. It involves not only reducing the amount of waste generated, but also adopting responsible waste management practices, such as recycling and WTE initiatives.

The Rise of Waste-to-Energy Plants

The need for sustainable energy in America goes beyond producing energy without emitting greenhouse gases from fossil fuels. It involves diversifying our energy sources, lessening reliance on imported fuels, and fostering economic development and job opportunities in various sectors. By prioritizing sustainable energy, we aim to create a cleaner environment, enhance energy security, and trigger economic growth through the expansion of job markets in crucial industries.

To address the dual challenge of managing our ever-increasing waste and reducing our dependence on fossil fuels, we must have an innovative solution. This is where the concept of WTE plants emerges as a beacon of hope. WTE plants are innovative facilities that turn waste into usable energy, offering a sustainable alternative to normal waste disposal methods.

In the United States, where a whopping 390 million tons of waste is produced each year, WTE plants offer a way to responsibly manage the leftover waste after recycling and composting.

Case Study: Reworld Waste’s Impact

Reworld Waste LLC, previously known as Covanta, a leader in the field, operates state-of-the-art WTE facilities that redirect waste from landfills, harnessing its energy potential through the combustion of MSW (Multiple Solid Waste). The innovative process transforms remaining waste, post-recycling, into electricity for homes and businesses, or steam exported to industries. This high-tech, advanced approach to waste disposal not only provides a viable energy source but also addresses environmental concerns by significantly reducing greenhouse gas emissions, particularly methane.

Landfills, as identified by NASA scientists, are recognized as significant methane emitters; and methane is 84 times more potent than CO₂ as a climate-warming gas.

Reworld’s WTE facilities make a substantial impact annually:

  • They reduce 21 million tons of greenhouse gas emissions.
  • They continuously power more than 1 million homes.
  • They recycle an impressive 600,000 tons of metal.

The process involves taking non-hazardous waste, otherwise destined for landfills, and combusting it to generate steam for electricity production. The ash produced undergoes processing to recover metal for recycling, while gases are carefully collected, filtered, and cleaned to minimize environmental impact. While it sounds simple, it is an intricate process that requires advanced technology and precision, and expertise mastered by Reworld.

The benefits of WTE extend beyond efficient waste disposal:

  • It is recognized as a technology that actively mitigates climate change.
  • WTE facilities are unique in reducing greenhouse gases, playing a crucial role in addressing climate change—e.g., for every ton of municipal solid waste processed, Reworld reduces greenhouse gases by up to 1 ton.
  • WTE facilities provide reliable energy to power more than 1 million homes 24/7.
  • The process recovers more than 600,000 tons of metal each year for recycling, equivalent to the steel needed for more than 450,000 automobiles.

Reworld’s commitment to sustainable practices and cutting-edge technology highlights a significant step towards a cleaner, more environmentally responsible future.

Environmental Benefits of Waste-to-Energy Plants

Utilizing WTE plants instead of landfills brings numerous advantages.

Reducing Landfill Waste: WTE initiatives play a crucial role in cutting down the amount of waste sent to landfills. Up to 80% of materials in landfills potentially could be reused or recycled. Diverting this material to WTE plants prevents it from causing harm by releasing toxic substances into water, soil, and air.

Generating Massive Energy: Well-planned WTE plants can generate significant amounts of energy, powering the creation of heat and electricity. Recognizing that waste cannot be entirely eliminated, these initiatives provide a second life to waste materials, transforming them into essential resources for human survival.

Environmentally Sound Process: The WTE process itself is environmentally friendly. It operates without relying on fossil fuels or non-renewable resources. WTE plants can even sustain themselves, producing energy while preventing the release of greenhouse gases. According to TRVST, an environmental organization, the power generated from WTE plants has the potential to save the use of 200,000 barrels of oil annually.

Mechanical Insulation’s Role in Waste-to-Energy Plants

In the journey toward a greener and more sustainable future in the United States, mechanical insulation companies like MC&I, Inc. play a crucial role by manufacturing energy-reducing storage tank insulation systems. One of the key ways MC&I, Inc. contributes to this mission is through insulating such tanks in the WTE sector. These storage tanks are utilized for a variety of applications, such as fire protection storage water that feeds a wet sprinkler system in the facility, or for cooling water used in the process.

Why is this important?

Mechanical insulation for storage tanks in WTE plants serves as a cornerstone for environmental responsibility. By providing efficient thermal protection from the atmospheric elements, products like MC&I’s RIDGLOK® Vertical Standing Seam Panel Insulation Systems contribute to the overall effectiveness of these plants, maintaining optimal temperatures and conditions within the storage tanks to make the process even more eco-friendly. Well-insulated tanks help optimize the energy production process, making it more efficient and environmentally friendly.

This commitment to insulation aligns with the broader goal of creating a sustainable America. It is not just about converting waste into energy, but doing so in a way that minimizes environmental impact and lowering energy costs.

The mechanical insulation industry—together with companies like MC&I, Inc. and Reworld—is shaping a future where innovation and environmental consciousness go hand in hand, creating a more sustainable and greener America.

OSHA Heat Illness Rule & Industry Reactions

U.S. Department of Labor Announces Proposed Rule for Extreme Heat Protection

As reported in the June Insulation Outlook article “Heat Illness Prevention: 5 Steps for Employers to Take” by NIA Legal Counsel Gary Auman:

“As of May 2024, OSHA remained engaged in the rulemaking process to develop a standard to cover heat illness prevention. Acting Secretary of Labor Julie Su predicted that a proposed standard would be available for public review by October 2024. She also predicted that a final standard on heat illness prevention would be in place by the end of 2024.”

From OSHA:

On July 2, the U.S. Department of Labor released a proposed rule for Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings.

The proposed rule would require employers to develop an injury and illness prevention plan to control heat hazards in workplaces affected by excessive heat. Among other things, the rule would require employers to evaluate heat risks and—when heat increases risks to workers—implement requirements for drinking water, rest breaks, and control of indoor heat. The rule would also require a plan to protect new or returning workers unaccustomed to working in high heat conditions.

Employers would also be required to provide training, have procedures to respond if a worker is experiencing signs and symptoms of a heat-related illness, and take immediate action to help a worker experiencing signs and symptoms of a heat emergency.

The public is encouraged to submit written comments on the rule once it is published in the Federal Register. OSHA also anticipates a public hearing after the close of the written comment period. More information will be available on submitting comments when the rule is published.

In the interim, OSHA continues to direct significant existing outreach and enforcement resources to educate employers and workers, and hold businesses accountable for violations of the Occupational Safety and Health Act’s General Duty Clause, 29 U.S.C. § 654(a)(1), and other applicable regulations. Record-breaking temperatures across the nation have increased the risks people face on the job, especially in summer months.

The agency continues to conduct heat-related inspections under its National Emphasis Program—Outdoor and Indoor Heat-Related Hazards, launched in 2022. The program inspects workplaces with the highest exposures to heat-related hazards proactively to prevent workers from suffering injury, illness, or death needlessly. Since the launch, OSHA has conducted more than 5,000 federal heat-related inspections.

From the Associated Builders and Contractors (ABC):

On July 2, ABC responded to OSHA’s Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings proposed rule.

“ABC continues to believe employers should equip their employees and leadership teams to develop their own safety plans, unique to their jobsites, and we strongly encourage review of all applicable OSHA rules and guidelines,” said Greg Sizemore, ABC Vice President of Health, Safety, Environment, and Workforce Development. “We also provide tools to employers so that they can equip and empower supervisors to recognize the signs and symptoms of heat illness, as well as provide necessary rest, water, and shade that is dependent on local conditions. Our members work to ensure that jobsites are safe and implement the most appropriate practices for working in extreme heat conditions that focus on the individual worker, based on CDC recommendations.

“However, those protections must be flexible in response to the fluid nature of the construction environment, and unfortunately, some of the unworkable provisions in the proposed rule could weaken contractor efforts to prevent heat stress for workers,” said Sizemore.

ABC will continue to review and analyze the more than 1,000 pages of the proposed rule.

From Associated General Contractors (AGC):

On July 2, AGC CEO Jeffrey D. Shoaf responded to the release of OSHA’s new proposed federal heat safety rule.

“The proposed new federal heat safety rule codifies many of the heat safety practices the construction industry already uses to protect workers. Those measures, which broadly fall into the categories of water, rest, shade, and training, were crafted by construction firms as part of their general duty obligations to protect workers and keep them healthy.

“It is disappointing, however, that federal officials have not addressed the disparate impacts of heat in various parts of the country. In short, the impacts on worker safety of a 90-degree day in Mississippi are different than a 90-degree day in Alaska. The final version of the rule should take into account regional differences in weather patterns.

“The proposal also lacks any emphasis on the role workers must play to protect themselves from the heat. Heat safety does not begin at the job site and the rule should include measures designed to reinforce the role workers play in protecting themselves. These measures include self-hydrating, understanding how common health conditions and medications contribute to heat stress, and avoiding the excessive consumption of drinks containing caffeine and alcohol during periods of extreme heat. All of which the agency is aware.

“We appreciate the opportunities we have had to help federal safety officials learn about successful methods of protecting workers on job sites. That communication is one reason why so many of the measures outlined in the proposed new rule track with industry practices that are already in use. We are in the process of reviewing all the details of the new proposal with our members to ensure we can provide feedback to agency officials.

“Overall, this proposed new rule provides a starting point for creating measures to protect workers that are based on what the industry is already doing. We look forward to working with federal officials to craft a final rule that includes effective measures for firms and workers to follow. That final rule should also avoid the kind of one-size-fits-all approaches that will do more to hamstring firms than to protect workers.”

Clear and efficient communication in warehouse2 or factory environments can minimize risk and improve productivity, and this is where advanced communication technologies can play a vital role. Communication is especially important in the mechanical insulation industry, which involves complex projects that require coordination and collaboration among various teams in potentially dangerous environments. Advanced communication headsets can help minimize risks on site, as workers can communicate instantly, eliminating potentially dangerous hand signals or misinterpreted shouted commands. A good headset with noise reduction can help filter background noise while protecting hearing and allowing for clear communication in environments with high background noise.

Key Features to Look for in Communication Headsets for the Mechanical Insulation Industry

In the mechanical insulation industry, effective communication is crucial for safety and efficiency. Good communication between team members is greatly enhanced by using communication headsets, but there are several key features to consider.

  • Noise reduction: Noisy environments are not uncommon in the mechanical insulation industry. Therefore, it is important to choose communication headsets that feature noise-reduction technology to filter out background noise.
  • Durability: Choose headsets that are durable and can withstand impact, vibration, and the sort of rough handling they can expect on the factory floor.
  • Long battery life: The last thing you want is for workers to be wasting time searching for fully charged headsets or batteries to maintain communication throughout the day. Headsets with a long battery life reduce the need for frequent recharging and allow workers to concentrate on their main tasks.
  • Reliability: To facilitate seamless communication between entire teams, ensuring that critical information is conveyed accurately and without any delay, reliability is crucial.
  • Comfort: Many workers will need to wear communication headsets for the entire workday, or at least for extended periods. Therefore, comfort is essential—otherwise there will be a temptation to remove headsets whenever possible, which could have safety implications. Choose headsets that provide a comfortable fit designed for all-day wear.
  • Hearing protection3: In any industry that may involve exposure to loud noise, there can be hearing damage. Select headsets that can safeguard hearing while providing clear communication. Also look for a noise-reduction rating (NRR) to ensure your headset can provide adequate protection for the noise levels.
  • Multi-channel options: In complex work environments where there may be multiple teams working on different projects, having the ability to set different channels for each team allows seamless communication.

Exploring the Future of Communications in Project Management Technology

The future of project management is likely to be heavily influenced by advanced communication technology that will revolutionize the way teams collaborate and communicate. Some key trends to look for include the increasing use of more powerful and intuitive mobile devices with project management tools that are optimized for team members to enhance flexibility and efficiency.
