I needed to match present aluminum tape to seal some exterior windows here n the desert to keep out sand and prevent the whistling of strong winds. It was the perfect color match and strength to do the job and it arrived on time!!!!

Great tape. Use this stuff to seal up some A/C ducting that a previous installer used a cloth-based duct tape. It fixed to air leak and the A/C is cooling the house down faster and will probably outlast the house.

Great price for a quality product.

The tape is very easy to apply and when installed is extreemly long lasting. It is a must to stop air leaks around the cooling unit, and the tape must be able to withstand years of use without deterioration. The old, failed cooling unit had also been installed in the factory in 2005 with this exact type of tape (now 2023) and it was still in excellent condition when I removed the original cooling unit. Obvoiusly this tape lasts.

This was so easy to use for a minor furnace repair. Fixed the problem completely. Recommend highly.

I didnt take out the A/C unit from the window and there was a draft coming in. I used the tape to seal the sides of theA/C and it did a good job.

I didn’t fine any flaws

I used this for connecting new ductwork joints for a dryer exhaust line. Not sure Id call it heavy duty, as the aluminum is thinner than regular heavy duty duct tape, but it adheres well and easily shaped into the nooks and crannies of the connections.
