Armaflex Foam Duct Liner

Armaflex Foam Duct Liner

Armaflex foam duct liner by Armacell is a flexible thermal insulation with a self-adhering backing. It is a closed-cell elastomeric foam that can reduce or eliminate conditions amplifying biological contamination and bioaerosols in commercial air conveyance systems.

Engineered to control condensation, Armaflex foam duct liner has an inherent vapor retarder and requires no additional mastic or coatings. It is non-wicking and has a very low rate of water absorption. It continues to prevent water infiltration even after incidental mechanical abuse. It is non-dusting, contains no formaldehyde, and withstands temperatures of 250 F (121C) when tested according to ASTM C 411.
