Waterproof HVAC Sealing Tape

Nashua FoilMastic Butyl Rubber Tape is a heavy-duty waterproofing repair tape built for indoor and outdoor sealing of low, medium and high-pressure HVAC duct systems. It adheres to metal duct, fiberglass duct and flexible duct systems to create a permanent, instant watertight bond. The 2 mil printed aluminium foil backing carries a 43 mil butyl rubber mastic adhesive that stays flexible in all weather. It also seals gutters, roof details, chimneys, vent stacks and mobile-home metal panels.

30-Foot Roll With 43-Mil Adhesive

Each roll supplies 30 feet of 96 mm wide tape on a 3-inch core, giving enough length for multiple duct joints, gutter seams or rooftop penetrations. The thick butyl mastic fills gaps and conforms to irregular surfaces where thinner tapes would bridge and leak. It runs out when the repair area exceeds the roll length or when a wider tape is required for large flashing overlaps. The paintable foil surface accepts coating for UV protection or colour matching.

LDPE Liner And Dual Branding

A low-density polyethylene release liner protects the adhesive until application and peels cleanly without tearing. Because Nashua 360-45 and Polyken 360-45 are the same Berry Plastics product, the core may carry either brand depending on inventory; the tape formulation remains identical. Buyers who need a linerless format or a different adhesive chemistry will not find it here.

Questions about this item

Will the 96 mm wide roll cover the seams on my existing metal ductwork?

The 96 mm wide roll is designed for sealing seams on metal duct, fiberglass duct and flexible duct systems, so it will cover standard duct seams and cracks.

How can I confirm the butyl rubber adhesive has formed a watertight bond after application?

Press the tape firmly into place; the heavy-duty mastic creates an instant water-tight seal that you can verify by running water over the repaired area and checking for leaks.

Does the roll include a release liner, or do I need to buy one separately?

Each roll comes with an LDPE release liner already applied to the adhesive side, so nothing extra is required before use.
