Abstract
A single membrane insulation material comprising a flexible fluoropolymer coated substrate, an insulating material laminated to one side of said substrate, and an anti-porosity fluid barrier associated with said substrate and shielded by said insulating material from elevated temperatures at said one side. Also disclosed is the inclusion of a a melt bondable fluoropolymer adhesive layer between the flexible fluoropolymer coated substrate and the insulating material.
Claims4
An integrally formed insulating composite comprising:
- a flexible fabric substrate coated on opposite surfaces with polytetrafluoroethylene;
