Humidity and Moisture Resistance - The high level of humidity and moisture resistance of Aerocel ULP® enhances system life, enhancing insulation investment
ASTM E96 testing, both wet and dry cup, demonstrates that Aerocel® ULP™ is a vapor retarder by itself – no added barriers are required. Permeance rating of max .01 perm-inch.
Aerocel® ULP™ is the most resistant insulation material to water absorption – .1% by volume.
