Ap armaflex and armaflex fs fire and smoke duct liner and wrap are the original fiber free closed cell thermal and acoustical insulation for ducts. Closed cell foams mostly considered thermal external wrap not internal acoustical liners. Flame and smoke rating k flex duct liner gray in thicknesses of 2 50 mm and below has a flame spread rating of 25 or less and a smoke development rating. K flex duct liner gray is elastomeric closed cell insulation specially designed as a fiber free alternative to lining air handling units and ducts.

They are engineered to safeguard iaq attenuate hvac noise and reduce energy loss when used to line or wrap hvac ductwork. For most applications k flex duct liner gray needs no additional protection. It is manufactured without the use of cfcs hfcs or hcfcs. Its closed cell structure prevents condensation and moisture wicking and makes it an efficient insulation.
