Fiberglass Duct Wrap

Fiberglass Duct Wrap is used as a thermal insulation on interior heating and air-conditioning ductwork.  Our Fiberglass Duct Wrap is 1-1/2" thick with a 3/4# density and FRK Facing (Foil Reinforced Kraft).  Ductwrap is wrapped around the circumference of the duct and wired or pinned onto the duct, all seams are sealed with FRK tape.
