Seal, seam, and jacket HVAC duct and pipe insulation with FSK and ASJ tape. These aluminum foil, fiberglass scrim, and kraft paper laminates create a tough vapor barrier that holds strong across hot and cold service temperatures alike.
FSK (Aluminum/Scrim/Kraft) and ASJ (All Service Jacket) tape are the go-to closure system for HVAC insulation pros who need a seal that holds up job after job. Built from a tough laminate of aluminum foil, fiberglass scrim, and kraft paper, these tapes match the facing on foil-faced duct board and pipe insulation for a clean, professional finish every time.
Use FSK tape to seam and seal joints on foil-faced fiberglass duct board, close up rigid duct systems, and keep vapor barriers intact on insulation runs. ASJ tape is the perfect partner for white kraft, All Service Jacket faced duct and pipe systems, giving cold and dual temperature insulation a permanent, moisture resistant closure.
Both tape types feature a fiberglass reinforced scrim for excellent tear resistance and a malleable foil layer that conforms easily to curves, corners, and irregular surfaces. Acrylic adhesive delivers a fast, positive grab with long term holding power across a wide service temperature range, from well below freezing to well above 200 degrees Fahrenheit.
