Light weight fire-blocking insulation blanket with improved durability and handleability

摘要

A lightweight insulation blanket for aircraft insulation or the like includes a lofted fibrous batting laminated to a relatively tough or high-tensile sheet of thin material, which provides improved handleability and durability to the batting. The high-tensile sheet may be a flexible fire-blocking sheet or non-woven fabric of refractory materials, which may be reinforced by a scrim. The batting and laminated fire-blocking sheet may be encased in a protective covering.
