Closed Cell Duct Liner

It is ideal for use in large ducts and plenums where air velocities do not exceed 6 000fpm 30 5 m s.

Closed cell duct liner.

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. We ve added an additional column of characteristics that speci fiers should consider before finalizing. 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. 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.

Ap armaflex ap armaflex fs duct duct liner and wrap insulation. For most applications k flex duct liner gray needs no additional protection. K flex duct liner gray is elastomeric closed cell insulation specially designed as a fiber free alternative to lining air handling units and ducts. It requires no additional vapor barrier and meets the stringent flame and smoke testing required for use in air plenums.

Fiber free duct liner and wrap enhances the life expectancy of the hvac system and the comfort of the building occupants. They are engineered to safeguard iaq attenuate hvac noise and reduce energy loss when used to line or wrap hvac ductwork. A uniquely tough skin surface is easy to clean and functional providing an ideal surface to resist moisture and dirt. 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.

The closed cell foam in this duct liner makes it especially effective at protecting pipes from condensation and moisture. Owens corning quietr duct liner hd roll is a high density roll designed to be installed inside sheet metal ductwork or plenums with metal fasteners and adhesives. Johns manville linacoustic r 300 is a rigid fiberglass board that is specifically designed for lining hvac plenums and air distribution ductwork and meets or exceeds all astm c 1071 type ii duct liner requirements. 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.

The expanded closed cell structure and unique formulation inherently resists moisture vapor intrusion.

The double sided skin can be used with either side facing away from the applied surface resulting in less waste if one side. It is manufactured without the use of cfcs hfcs or hcfcs.

Closed cell foams mostly considered thermal external wrap not internal acoustical liners. Its closed cell structure prevents condensation and moisture wicking and makes it an efficient insulation.
