Abstract: A single membrane insulation material including a nonwoven insulation mat, a fluoropolymer dispersion surface coated to one side of the mat and a fluoropolymer film component laminated to the thus coated side of the mat under conditions of elevated temperature and pressure. The coating has a depth of penetration which is less than the total thickness of said mat.

Abstract: A flexible composite expansion joint material comprises a fluoropolymer containing woven fabric substrate with mutually perpendicular warp and fill yarns. The substrate is subdivided into plural segments which are arranged successively in a longitudinally extending assembly with the warp and fill yarns of each segment extending obliquely with respect to the assembly length. At least one other component extends over the assembly length. The successively arranged substrate segments are spliced together and integrally joined to the other component by lamination under conditions of elevated temperature and pressure.
