This tape is a must for ducts and works much better than the putty. Really sticky and seals well. Does not wear over time like duct tape (which you arent supposed to use on HVAC ducts anyway). It is also great for niche projects, even outside. I used this tape to patch rusty holes on the bottom of outdoor light poles before painting them. Its lasted 5 years and counting already.

This tape is excellent for sealing my HVAC ducting and air handler. very strong adhesive and the rubber helps it form to the surfaces and over screws. Only caveat is that removing the plastic film is a bit of a challenge to start. I had to use tweezers to catch an edge.

Easy to use. It's no so sticky that if you accidentally touch something it adheres permanently, but once pressed into place the bond is strong. We sealed a number of leaky high-pressure air ducts and it seems to work great.

The Nashua Foilmastic Sealant Tape, although expensive, is a great product. I am currently working on sealing the HVAC ducting that runs throughout the crawlspace, branching out from the distribution plenum. None of the ductwork was ever sealed and I am guessing that I was possibly losing 30-50% of the heater output (judging by how warm the crawlspace was during the middle of the winter). I plan to brush or wipe mastic sealant on the joints of the adjustable elbows, but am using the Nashua FoilMastic Sealant Tape on the straight runs and especially where the ducting attaches at the distribution plenum. I will also be sealing the cold air return runs to see if we can cut down on the dust, vapors and whatever else is blown back up into the living spaces when the heater is operating. The Sealant Tape is fairly easy to use and, because it is somewhat flexible, lays down along curved surfaces fairly well. Be sure to clean the ducting before applying the tape and then smooth and secure the tape fully with a small artist's squeegee. If used correctly the squeegee will easily press out most wrinkles. About the only difficulty for me was separating the backing from the tape, but that probably has more to do with bad eyesight and limited space to work in than anything. Using a sharp knife instead of a fingernail helped a lot. Other than that, I am very impressed with the Nashua Foilmastic Sealant Tape. By the way, Home Depot had the best price of any online reseller or local hardware store. So far, with only the distribution connections fully sealed, I can feel--and hear--a huge difference in the output. The furnace is cycling less often and it runs for a shorter period of time to heat up the living spaces. It is much quieter, especially in the living space near the furnace. I can't wait to see the results after all the ducting runs are fully sealed and insulated.

I have a shallow Delta Rib roof that will leak under ice dam conditions. After a huge rainstorm I had backup water leaking into the bedroom. The tape stickum is Butyl mastic. I cleared the tin of water and snow then used a weed burner to dry it out. Then, while the roof portion was still warm, applied the tape. Then I torched it with the burner to even more stitch it down. No new leaks.

Excellent tape with really strong adhesive and sealant. Far exceeds the thin tape used by contractors. Worth the extra cost.

I've been sealing all the HVAC ductwork in my basement prior to putting in a drop ceiling. FoilMastic is great for tricky to reach areas and it bonds extremely well. Wish it cost less though. I use mastic and/or regular foil tape in easier to reach areas.

I have done a bunch of things around my home to make it more energy efficient. To date, I've installed all new windows and sealed all of the doors, I've even placed child proof plastic prongs in each of the outlets along the outside walls of my home to stop air leaks. So, when I saw the 1.89 in. x 33.9 yd. Foil Mastic Sealant Tape available, I grabbed it immediately. I had installed a new more energy efficient central A/C system several years back, and I did seal the ducts in my basement with both foil tape and mastic, however, there are still obvious air leaks. This 1.89 in. x 33.9 yd. Foil Mastic Sealant Tape will take care of that.

Really nice adhesive on the back of this stuff. Won't tear like most foil tape. Made in the USA! I used foil tape all the time, I love the stuff. I use it for its actual purpose and so many other things. none of them I have used have adhesive like this tape though, this stuff is strong. Its very similar to the VHB tape but without the foam. The separator is is a thin layer of plastic rather than paper and is easy to remove. The plastic is also blue so you can clearly see the difference in the adhesive and the removable piece. Also makes it easier to clean up your mess when you are finished, you can see all your trash!
