Aluminum Foil Tape - Waterproof Insulation for HVAC Ducts - Heat Resistant Tape for Metal Repair - Duct Seal for Indoor & Outdoor Use - Pack of 2, 2 in x 210 ft, Silver

There is a lot of tape on this roll and it is durable and has super adhesion. DO NOT pull the backing off all at once as the tape will curl and when it sticks to itself, it is next to impossible to separate. Instead, peel off about 3-4" of the backing and then start wrapping, peeling off more of the backing as you proceed.I used this to seal off joints in my heating runs in my basement and it does a super job sticking to the aluminum plenums.Durable. I am very satisfied with the results.

I had quite a few places on my ductwork as well as on my furnaces (2). I made the classic mistake of using duct tape - which is NOT really for ducts the first 2 times I tried to remedy the leaks. Duct tape doesn't hold at all. This stuff was fantastic! Easy to use (once you get it started - you have to be able to remove the backing on the tape itself), sticks well, conforms to shapes rather easily... etc. If I could give it 10 stars I would!!!!!

Have used various brands of the aluminum tape. This product is the best ever. Adhesion to every surface I tried. I used it to reinforce the insulation under my 5th wheel RV. I exclaimed many times while working with the tape how much better it was over prior products. Obviously, I highly recommend this and would buy more as needed. Fast delivery also.

I don't use this tape for it's intended purpose, but it works great as a super strong masking tape.I am building live edge slab furniture and I have to fill cracks and voids that go clear through the slab with epoxy. This tape has great adhesion to the wood and to itself and with this type of tape I don't have to worry about leaks and a mess to clean up later.This aluminum tape removes very well also.

I ordered this tape to use with aluminum pipe bubble wrap in insulating my portable A/C exhaust hose in order to prevent heat from escaping. Since I had never used this kind of tape before, I was expecting a difficult time. However, I found it quite easy to use. Once you first separate the tape from the paper backing, the key is to cut your segments of the aluminum tape only, while leaving the end of the paper backing long enough to peel off without having to start all over again. The tape is very flexible and holds securely once applied. I recommend it for pipe and hose insulation jobs.

I am an HVAC contractor and use alot of different tapes to seal ductwork. This tape works great for a great price!

Poor adhesion on foil facing of polyisocyanurate rigid insulation to tape joints. Even when wiping joints with denatured alcohol and applying tape the next day, still a problem with foil tape separating within 24 hours inside a dwelling at 70 degrees.I purchased this to replace older foil tape which was doing the same thing.

Sticks well, pretty thick and heavy duty, especially for the price. Tears easily off the rolls but doesn't tear when it's not supposed to. Great for ductwork, and taping seams. I've used on ductwork, aluminum sheeting in attic, and on a Solatube. This tape is far more substantial than the cheap stuff they give you with the solatube. Doesn't get pinholes if it wrinkles.

Good I would buy again, better than the crap i had on thats for sure
