ABSTRACT:
A flexible composite multiple layer fire-resistant insulation structure has a primary facing surface and a secondary facing surface. There is at least one dimensionally stable membrane having a primary membrane surface and a secondary membrane surface. At least a portion of the secondary facing surface is attached to the primary membrane surface. There is also at least one lofted insulative layer having a primary insulative surface and a secondary insulative surface. The at least one woven fabric facing layer may be formed of various materials, including amorphous silica glass and S-glass fiberglass. Different weaving patterns may be used to weave the facing layer. The facing layer may include a fire resistive treatment, which may in turn include a phosphate containing compound, and more particularly, may include dicalcium phosphate. In certain embodiments, multiple layers of the above are provided, and the structure may be enclosed in an abrasion resisting sheath.
