NIA’s Thermal Insulation Inspector Certification™

NIA’s new Thermal Insulation Inspector Certification Program will educate participants on how to inspect and verify that the materials and the insulation system have been installed in accordance with the mechanical insulation specifications.

Benefits of a Certified Insulation Inspection
Inspection can be an integral part of QA/QC, commissioning, and other processes while helping to achieve the benefits the mechanical insulation system was designed for by verifying the materials and the installation are in compliance with the specifications, standards, or assessments of previously installed mechanical insulation systems.In addition to the certification, Professional Development Hours (PDHs) are awarded.

Who Should Take this Course

If you are responsible for areas such as contracts, maintenance, business development, QA/QC, project oversight, estimating, safety, management, product development, mechanical insulation system design, specifications, or inspections, you will want to have at least one person on your team with this certification.

Upcoming Courses:

Due to the ongoing COVID-19 situation, all current courses have been postponed. We are working now to secure new dates that will take place later this year. New dates will be announced as soon as they are available. Be the first to know about new class dates by contacting to be added to our interested-party list.

Additional details about the recertification process will be announced in 2020, at that time all Certified Insulation Inspectors will be contacted with more information.

What NIA Leaders Say about NIA's New Thermal Insulation Certification

“This program will be helpful in raising the bar for mechanical insulation contracting. I was very impressed with the detail and quality of the student materials and how knowledgeable all the instructors are.”
 John Lamberton, 2019–2020 NIA President-Elect, Chief Operating Officer, Irex Contracting Group, Class Participant

"I am very excited about the initiative for NIA to become the education and training leader in our industry. Using the knowledge of our membership to create curriculum is an example of how we can lead the industry to future success. We have online training as well as classroom instruction, and continue to add content to address the needs of the industry. Having tools available to train our employees is a huge benefit, but I am also excited that we have programs available to people outside of our association. Launching the Thermal Insulation Inspector Certification is the impressive result of our members working together to create a certification program that will elevate the awareness of the importance of mechanical insulation."
— Dana Vlk, 2019–2020 NIA President, and Senior Adviser, Distribution International, Inc.

"The Thermal Insulation Inspector Certification that NIA is developing has the potential to be a game changer in how systems are installed, the quality of the system, and it’s just going to raise the bar for the industry at all levels—manufacturing, contracting, distribution—everyone is going to have to be on their game because there will be oversight to ensure things are getting done per the specification."
— Dan Bofinger, NIA Immediate Past President and Regional Vice President, East, Specialty Products & Insulation
