ASTM-C1136 › Historical Revision Information
Standard Specification for Flexible, Low Permeance Vapor Retarders for Thermal Insulation
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers vapor retarders for thermal insulation, specifically, flexible materials with permeance of 0.10 perm or lower and surface burning characteristics of 25 flame spread/50 smoke or lower. These materials are intended for use at surface temperatures of 20 to 150°F (29 to 66°C). It does not cover mastics or barrier coatings applied in liquid form, nor materials intended for use as weather barriers.
1.2 This specification provides physical requirements for vapor retarders. Practice C 755 provides assistance in solving problems related to moisture vapor transmission through thermal insulation materials.
1.3 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.
