Aluminum 2'' X 13'' Foil Tape

Stuck a strip over a small tear in my ductwork and it’s still holding strong after a week of heat cycling. The adhesive grabs immediately and the foil backing cuts clean with scissors, which saved me a trip to the hardware store.

The roll is lighter than I expected for aluminum, and it sticks firmly to my duct work without peeling back at the edges. I've already patched two small gaps in my garage and it's holding up great so far.

This foil tape is perfect for sealing my HVAC duct connections, and the 2-inch width fits standard seams without any extra trimming. The adhesive grabs fast and stays put even in my hot attic, so I’m finally done patching leaks.
