Aluminum Foil Tape, 2 inch x 65 Feet (3.9 mil), Insulation Adhesive Metal High Temperature Heavy Duty HVAC Tape, Silver for Ductwork, Dryer Vent, HVAC

We got this to cover tiny holes and openings that our hvac installer left (sloppy job). we also covered a vent that was from something else and had to be diverted. This stuff worked great! completely covered anything you need it for,very sticky, easy to use,projects went quickly. It's been awhile since we used it and it is still sticking tightly likemthe day we put it on. I highly recommend and it can be used on things that get hot too. We used it on our furnace metal hood.

seal seams for cold and heat retention at windows .sticks well, works good.no fibers in this tape .

Has held good so far, used it to tape up fallen insulation inside a storage unit. It’s attached to a metal roof, which gets very hot in the summer, so we’ll see how it holds up over time. It’s been two months and so far so good

Used it to seal some gaps on my attic ac unit and it is easy to use and shaped really well around all the sharp corners.

I use it to seal my portable AC cover board, and it works great!

I use foil tape for anything and everything that requires a strong, durable, weatherproof tape, unless it's for something that is seen by others, since it is a silver foil like aluminum foil. Duct tape is a joke compared to this.

This tape is great for small projects around the house. I have used it a lot.

This is handy to keep nearby as a utility tape. Works on about everything and stays put too. No more clamping down the dryer vent pipes with this stuff. I keep another roll in the RV too.
