SR Insulated Ducting
ThermoFlo Technologies 'SRB' series is an industrial quality insulated duct, manufactured 'tough' for consumers' and installers' peace of mind.
SR Insulated Ducting consists of a three ply polyester laminate, fiberglass reinforced scrim & galvanized spring steel wire, all wrapped with fiberglass insulation which provides an outstanding combination of strength and tear resistance. A heavy duty fire retardant black polyethylene vapor barrier adds extra durability. The insulation reduces noise, heat loss and condensation.
