Armacell AP Coilflex CFR10057050 1"x47"x50'

AP Armaflex duct liner and wrap are the original fiber-free, closed-cell, thermal and acoustical insulation for ducts. They are engineered to safeguard IAQ, attenuate HVAC noise, and reduce energy loss when used to line or wrap HVAC ductwork. Lining or wrapping ducts will result in more comfortable occupant spaces, reduced energy costs and quieter indoor environments.
