Product Data Sheet Fiberglas Thermal Insulating Wool (TIW) Types 1-HP & II-HP Insulations Type I-HP Type II-HP Description Fiberglas Thermal Insulating Wool (TIW) Types I-HP and II-HP Insulations are off-white, noncombustible wool with resilient, inorganic glass fibers bonded with a thermosetting resin. TIW Type I-HP Insulation is available in rolls; TIW Type II-HP Insulation comes in batts. Key Features Excellent thermal performance contributes to lower fuel costs due to reduced heat loss. Easy to handle and install. The insulation is easily impaled over welded studs or pins, or may be held in place with wire ties, metal lath or lagging. There is no tendency for pin- hole elongation under vibration situations, a frequent source of heat leaks in heavier products. Large batts or blankets cover greater areas quickly, eliminating tedious block-by-block hand layup and drilling for studs in hard insulations. Can be used in direct contact with steel, copper and aluminum without corrosive effects. Product Applications Fiberglas TIW Type I-HP Insulation is used in applications up to 1,000F (538C) at maximum recommended thickness requiring a lightweight insulation, such as that used in panel systems, flexible wrap, industrial ovens or surfaces having irregularities. Its low compressive strength does not make it suitable for use as a base wool for metal mesh blankets. Installation Fiberglas TIW Type II-HP Insulation is especially suitable for use in metal mesh blankets and for use on boilers, vessels and many other types of industrial equipment operating at temperatures up to 1,000F (538C) at maximum recommended thickness. It may also be used in panel systems for precipitators, ducts and breechings where more compressive resistance than Fiberglas TIW Type I-HP Insulation is needed. Fiberglas TIW Types I-HP and II-HP Insulations can be installed directly on heated flat and curved Physical Property Data Property Test Method Type I-HP Value Type II-HP Value Equipment Operating Temperature Range 1 ASTM C411 Up to 1,000F (538C) Nominal Density ASTM C167 1.0 pcf (16 kg/m 3 ) 2.5 pcf (40 kg/m 3 ) Shot Content ASTM C1335 Negligible Water Vapor Sorption ASTM C1104 < 2.0% by weight at 120F (49C), 95% R.H.

Maximum allowable thickness at 1,000F (538C): Type I-HP - 8.5" (216mm); Type II-HP - 6" (152mm). 2. The surface burning characteristics of these products have been determined in accordance with UL 723, ASTM E84 or CAN/ULC-S102. 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 and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating. Availability Sizes TIW, Type I-HP (Rolls Widths, in. (m) Thickness, in. (mm) Length, ft.
