Save Labor & Material Costs. Install it Faster with an Itch-Free, Low-e Duct Solution.

FI-FOIL® high thermal performance reflective HVAC duct Insulation is a smart alternative to fiberglass, foam board and spray foam insulation.

FI-FOIL® HVAC Duct Insulation meets the highest industry standards. With Class A and Class 1 flammability ratings and as a Class 1 vapor retarder, our duct insulation provides superior protection from fire and moisture accumulation.

Low-e surfaces of FI-FOIL® HVAC Insulation wrap reflect heat rather than absorb it, providing superior thermal resistance to keep buildings cooler in the Summer and warmer in the Winter. The result is greater efficiency and performance year-round.

FI-FOIL® HVAC insulation is a clean, sustainable solution to improve energy efficiency, comfort and building resilience.
