Impresa Aluminum Foil Tape 2-Pack - 1.9 in x 150 ft, 3.4 mil - Contractor-Grade Foil Duct Tape - Heat & Moisture Resistant for HVAC, Metal Repair & Insulation

Used them today. They have a plastic film on the back that you have to peel off. It can be a bit of a pain starting to pull the film off at first , put once started it peels off easily. The tape works and stick so well that that is a minor issue but I thought it maybe good to mention. I fully recommend these.

Excellent. Sticks well :-)

Perfectly work !!

a little thin but I knew that but It is a good value

Covers well, sealed ven holes as expected. I got no questions on quality, thickness was well, ease of use as expected.

Using this on foil-coated foam insulation in cold and wet weather. It sticks easily and well even at temps below 40 degrees. Was a bit difficult to get the paper backing separated at the beginning of the roll, but it peels very easily after that. I just made sure to fold over a small bit each time I end a length of taping. It is foil, so note that the edges are plenty sharp enough to cut fingers if you are not careful or not wearing gloves. Excellent product!

I did hvac for 10 years, and don't get me wrong, this is decent quality (average that is) foil tape. So, I've used plenty of brands, probably a couple miles worth of foil tape over the years. This does suffice. However the Nashua is nearly twice as thick, and nearly double the adhesive properties. Currently putting up foil backed radiant barrier (insulation) in my garage and taping all seams together, and against the studs etc. I first purchased a roll of the 322 just to see how it performed. Loved it so ordered a 2nd roll. Then realized I needed at least 1 final roll to complete the project...not in stock, so I had to go with this brand. Again, it works. But nowhere near the Nashua. Also, yard for yard, price is just about the same. A 50 yard roll of Nashua is a little over $6. These, $20ish for 150 yards. Imo, a no brainer to get the better version unless you're in a hurry and shipping time affects your decision. Think of standard aluminum foil, vs heavy duty Reynolds wrap. Then think of cheap dollar store duct tape vs name brand far as adhesive properties. Best way I can put it. Happy taping! 😃

We used this for a heat barrier in the attic. It adheres very well. Worked out great for us.
