Fibrous Insulations<\/span><\/b><\/p>\n

Fibrous insulations are
\ncomposed of small-diameter fibers that finely divide the air space. The fibers
\nmay be organic or inorganic and they are normally (but not always) held
\ntogether by a binder. Typical inorganic fibers include glass, rock wool, slag
\nwool, and alumina silica.<\/span><\/p>\n

Mineral Fiber (Fiberglass
\nand Mineral Wool)<\/span><\/b><\/p>\n

Mineral fiber insulations
\nare defined by ASTM as insulations composed principally of fibers manufactured
\nfrom rock, slag, or glass, with or without binders. <\/span><\/p>\n

Fiberglass and
\nmineral wool products fall in this category. There is some confusion concerning
\nthe nomenclature used for these materials. Fiberglass products (sometimes
\ncalled “fibrous glass” or “glass wool”) and mineral wool products (sometimes
\ncalled “rock wool” or “slag wool”) are covered by the same ASTM “mineral fiber”
\nspecifications, and sometimes by the same type and grade. Specifiers are
\ncautioned to call out both the specific material and the ASTM type and grade
\nwhen specifying these products. For example “Fiberglass pipe insulation meeting
\nthe requirements of ASTM C547 Type I, Grade A” or “Mineral Wool pipe insulation
\nmeeting the requirements of ASTM C547 Type II, Grade A.” A number of ASTM
\nmaterial standards cover mineral fiber products.<\/span><\/p>\n

Mineral Fiber Pipe<\/span><\/b><\/p>\n

Mineral fiber pipe
\ninsulation is covered in ASTM C547. The standard contains five types classified
\nprimarily by maximum use temperature.<\/span><\/p>\n

The standard further
\nclassifies products by grade. Grade A products may be “slapped on” at the
\nmaximum use temperature indicated, while Grade B products are designed to be
\nused with a heat-up schedule.<\/span><\/p>\n

The specified
\nmaximum thermal conductivity for all types is 0.25 Btu
\nin\/(hr ft\u00b2 \u00b0F) at a mean temperature of 100\u00b0F.<\/span><\/p>\n

The standard also
\ncontains requirements for sag resistance, linear shrinkage, water-vapor
\nsorption, surface-burning characteristics, hot surface performance, and
\nnon-fibrous (shot) content. Further, there is an optional requirement in ASTM
\nC547 for stress corrosion performance if the product is to be used in contact
\nwith austenitic stainless steel piping.<\/span><\/p>\n

Fiberglass pipe
\ninsulation products will generally fall into either Type I or Type IV. Mineral
\nwool products will
\ncomply with the higher temperature requirements for Types II, III, and V.<\/span><\/p>\n

These pipe
\ninsulation products may be specified with various factory-applied facings, or
\nthey may be jacketed in the field. Mineral fiber pipe insulations systems are
\nalso available with self-drying wicking material that wraps continuously around
\npipes, valves, and fittings. These products are intended to keep the insulation
\nmaterial dry for chilled water piping in high-humidity locations. Mineral fiber
\npipe insulation sections are typically supplied in lengths of 36 inches, and
\nare available for most standard pipe and tubing sizes. Available thicknesses
\nrange from \u00bd” to 6″.<\/span><\/p>\n

<\/p>\n

Mineral Fiber Blanket<\/span><\/b><\/p>\n

Mineral fiber blanket
\ninsulation for commercial and industrial applications is covered in ASTM C553.
\nThe standard contains seven types classified by maximum use temperature and thermal
\nconductivity.<\/span><\/p>\n

The standard also
\ncontains requirements for flexibility, water-vapor sorption, odor emission, surface-burning
\ncharacteristics, corrosiveness, and shot content.<\/span><\/p>\n

These insulations
\nare flexible and are normally supplied as batts or rolled blankets. Dimensions
\nvary, but thicknesses from 1″ to 6″ are typically available. The products may
\nbe specified with various factory-applied facings, or may be ordered unfaced.<\/span><\/p>\n

<\/p>\n

Mineral Fiber Block and
\nBoard<\/span><\/b><\/p>\n

Mineral fiber block and
\nboard insulation is covered in ASTM C612. This standard contains five types classified
\nby maximum use temperature and thermal conductivity.<\/span><\/p>\n

Each of these types
\nis further classified by compressive resistance. Category 1 materials have no requirement
\nfor compressive resistance, while Category 2 materials require a minimum
\ncompressive resistance value. Density is not a performance measure and has been
\nremoved as a requirement in ASTM C612.<\/span><\/p>\n

The standard also
\ncontains requirements for linear shrinkage, water-vapor sorption,
\nsurface-burning characteristics, odor emission, corrosiveness to steel,
\nrigidity, and shot (non-fibrous) content. Further, there is an optional
\nrequirement in ASTM C612 for stress corrosion performance if the product is to
\nbe used in contact with austenitic stainless steel. Fibrous glass boards will
\ngenerally meet Types I, II, or III. Mineral wool products will generally comply
\nwith the higher temperature requirements for Types IVA, IVB.<\/span><\/p>\n

These
\nproducts are supplied in rigid and semi-rigid board form. Dimensions will vary,
\nbut typical available thicknesses range from 1″ to 4″. The products may be
\nspecified with various factory-applied facings, or may be ordered unfaced.<\/span><\/p>\n
