Closed Cell Duct Liner

Ap armaflex ap armaflex fs duct duct liner and wrap insulation.

Closed cell duct liner.

It is manufactured without the use of cfcs hfcs or hcfcs. The features benefits list below submitted by a manufactur er of closed cell foam entices design ers to specify closed cell foam as a duct liner. Ap armaflex sa duct liner wrap is a black flexible elastomeric thermal insulation. Closed cell foams mostly considered thermal external wrap not internal acoustical liners.

A uniquely tough skin surface is easy to clean and functional providing an ideal surface to resist moisture and dirt. Fiber free duct liner and wrap enhances the life expectancy of the hvac system and the comfort of the building occupants. We ve added an additional column of characteristics that speci fiers should consider before finalizing. The closed cell foam in this duct liner makes it especially effective at protecting pipes from condensation and moisture.

The double sided skin can be used with either side facing away from the applied surface resulting in less waste if one side. They are engineered to safeguard iaq attenuate hvac noise and reduce energy loss when used to line or wrap hvac ductwork. K flex duct liner gray is elastomeric closed cell insulation specially designed as a fiber free alternative to lining air handling units and ducts. The microban antimicrobial protection is registered by.

As the world s most recognized brand in flexible closed cell foam insulation ap armaflex and ap armaflex fs add long term value and long lasting performance to hvac projects. Its closed cell structure prevents condensation and moisture wicking and makes it an efficient insulation. 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. For most applications k flex duct liner gray needs no additional protection.

It requires no additional vapor barrier and meets the stringent flame and smoke testing required for use in air plenums. Linacoustic r 300 s airstream surface is coated with our proprietary permacote coating which provides a durable and smooth surface that is resistant to the accumulation of.

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.

It is ideal for use in large ducts and plenums where air velocities do not exceed 6 000fpm 30 5 m s. The expanded closed cell structure and unique formulation inherently resists moisture vapor intrusion.
