Manufacturer: ITW Insulation Systems
Product Description

SARAN™ 540-CX Vapor Retarder Film is composed of a film of the barrier polymer polyvinylidene chloride (PVDC). To provide strength and support, other specialty polymers were coextreded together. The portions of the coextruded film create a vapor retarder and jacket material for mechanical insulation systems, that we know to be flexible and durable. The design of SARAN™ 540-CX Vapor Retarder Film is to help prevent water absorption, powerfully resist moisture vapor drive into the insulation, and is not a known nutrient source for mold or mildew.

A permeance rating of 0.02 perms meets or exceeds standard industry requirements for vapor retarders in cold service.


SARAN540-CX Vapor Retarder Film is supplied either factory applied on straight lengths of TRYMER*or XPS PIB insulation or in easy-to-use rolls for field application. Width: 35.5" (90 cm) Length: 375' (114 m)
