Aluminium foil tape for HVAC sealing

This 3.9 mil thick aluminium foil tape uses a pressure-sensitive adhesive that bonds to ductwork, dryer vents and pipe insulation. The roll measures 2 inches wide by 65 feet long and is rated waterproof for indoor projects. It withstands long-term temperatures up to 120 and short-term peaks of 130.

Suited for ductwork and pipe repairs

The tape handles smooth, flat or irregular metal surfaces and resists UV, moisture, flame and chemicals without leaving residue on removal. It is not intended for outdoor structural bonding or applications that require a certified fire-barrier rating.

Thickness of 3.9 mil balances strength

At 0.1 mm the foil resists tearing during application yet conforms to curved pipe surfaces. This single dimension determines whether the tape will survive handling and fit the contours of your specific duct or pipe job.

Questions about this item

How do I install this 2 inch x 65 feet aluminum foil tape so it adheres properly to ductwork?

Clean the surface, peel the paper liner, press the 3.9 mil foil firmly with a squeegee to remove air pockets; the thicker foil resists wrinkling so you can reposition once if needed.

Will the pressure-sensitive adhesive on this HVAC tape need replacement after seasonal temperature swings?

The adhesive is rated for long-term exposure at 120°C and short-term at 130°C, so it maintains bond through normal heating and cooling cycles without drying out.

At what temperature does this 3.9 mil foil tape reach its limit during continuous use?

Continuous service limit is 120°C; brief peaks up to 130°C for about half an hour are tolerated before the adhesive begins to degrade.
