Textile Glass

Textile Glass (e-glass) fibrous thermal insulation is
produced from textile glass fibers (e-glass) and is needled into insulation
felts without the use of binders. The material is used as a thermal insulation
component in the fabrication of insulation systems for use on machinery and
equipment at temperatures up to 1,200°F. These products are covered in ASTM
C1086 and in MIL-I-16411F.

The Standard contains requirements
for thickness, mass per unit area, apparent thermal conductivity, hot surface
performance, tensile strength, and combustibility. For comparison purposes, the
thermal conductivity of the material is a maximum of 0.29 Btu?in/(hr?ft²?°F) at
75°F.
