Aluminum Foil Tape, Metal Duct Tape, 2 in x 99 FT (4 mil), Professional Grade for HVAC, Patching Hot, Cold Air Ducts, Metal Repair, Ductwork.

I bought this to tape up some foil faced foam board insulation and it worked AMAZING. Super sticky but be careful not the cut yourself on the edges like I did - after all, it is metal based. I ran out of this and had to run to a local big box store and they had it too but it was not as thick as this. The thinner stuff much more difficult to peel the backing off and work with - I highly recommend this (4mil) tape - you won't regret it!

Good for my art projects

During the summer, I would find that the cellar got so cold that it was uncomfortable to spend time down there. A little investigation showed that the ducts, especially those right around the heater area, were leaking profusely. I used most of the roll of tape and it took some time to isolate and tape up the leaks, but in the end, the cellar is now at a much warmer temperature during the summer. The tape was easy to apply and molded itself well onto tiny cracks and along seams in the ducts. The tape seems to be holding up well and I don't see the need to do it again in the near future.

This product is heavy aluminum foil with adhesive applied on one side. It worked great, but as I was removing it I noticed that it had cut my finger. It's sharp, so be careful, it's not just metallized duct tape.

Used this to adhere aluminum bubble wrap to my windows to keep hot temps down. Easy to use, Peels away from paper tape well and adheres nicely. Much better than Duct tape for this purpose.

Just the right price for this roll of tape. Good quality for household use.

It’s like thick aluminum foil. It has a peel off backing, worked great for sealing around vent ducts behind cover. It does help with adhesion if you wipe off the area first. It’s thin enough to manipulate it to form it to where you need it. I used it to seal around the space between duct and wall. Very happy with this purchase.

Doesn't stay stuck

Super product
