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

Strong, stuck on pretty well, paper doesn't rip wrong actually peels real nice.

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.

This tape is so useful in so many applications, I feel a little guilty for using it to patch up literally everything and anything. I fixed the broken mailbox flap. I taped the frames back to my glasses with small silver pieces. It even looks stylish! I "decorated" some deteriorated kitchen cabinet doors.The tape is easy to separate from its backing if you pull on the silver part instead of the backing part.

used it in my driver vent worked like a charm

At first I wasn't too sure about this tape - and then I actually used it. Sticks very well and I think it will hold up well. Great value for the roll, I'm glad I picked this one.

Bought to cover seams for rv insulation. The tape works, it holds, has stickiness, very durable. Don’t purchase thinner tape. This seals very well.

Strong and easy to use.

-Edit- It's been 5 months and the tape is still going strong on my liquid cooling CPU cooler. For maybe 3 months I had been mining Bitcoin with this PC so it's had prolonged elevated temps and the tape glue seems to be holding wonderfully. I would recommend this tape to anyone.This is NOT that bogus "Aluminized Mylar" (thermal blanket) tape where they take plastic and spray like a single micron worth of Aluminum over it, call it "Aluminum Tape", and it's barely sticky. This is thick-ish Aluminum foil with seemingly good quality glue, or whatever you call it. I folded it in half and was trying to feed it through a small slit between computer case and liquid cooling fan (wanted to close the venting around the fan to keep airflow moving from intake to exhaust) and it kept getting stuck to the fan where I had to pull a bit to get it off and then re-fidget the tape so it was straight and then try again, so this stuff is fairly sticky. I used a smaller piece on the corner and it wasn't sticking the best, but after cutting a bigger chunk and touching up the corner that stuff seems ON THERE, I disagree with reviews that say this stuff doesn't stick to itself, seems pretty good to me. The liquid cooling fan/coil gets pretty warm (not heating duct hot, but still fairly warm to point it might dry out the glue or something) so I will try to update as the tape ages to see if it keeps its strength and stays on there (if this listing is still around/active by then >_>).I recommend this tape to a friend having used it just the one time, and now I've got lots for later jobs down the road and it wasn't much more expensive than the tiny 5 yard rolls or whatever.
