Aluminum Foil Tapes

Dead-soft aluminum foil tapes for aerospace masking, military sealing, and HVAC duct work — from Boeing- and MIL-spec aircraft grades to UL 181 listed and cold-temperature insulation tapes

Every tape here uses a dead-soft aluminum foil backing that conforms to seams and contours without cracking — but they split into two families. The aerospace and military grades carry Boeing, SAE-AMS, and MIL specifications for aircraft masking, stripping, and high-spec sealing. The HVAC and insulation grades are UL-listed or cold-temperature tapes built for duct sealing, vapor barriers, and jacketed insulation — most sold by the case. Use the comparison table to match foil thickness, adhesion, and approvals to your job.
