Great adhesion!! Perfect for my needs.
I needed to replace some foam tape on the inside of my window a.c. and this worked perfectly. Sticks beautifully.

Worked great
I have ill-fitting window screens with fairly large gaps. This did the trick. I closed the gap and finally shut out the bugs.

It is what it is
What can you say about this. I could tell you this though! The manufacturers do need to add a little more sticky to their product. It does not hold very long, or for that manner very well. You asked, I told you.

Great for a sliding door creation!
Great deal for our sliding door ! We installed a cat/ pet door with a flow on it so our cat could go out 24/7, and air and water would always just make its way in the kitchen . By putting this on the side of the sliding door, and then rubbing white caulk on it - it created a waterproof seal on the foam . Which doesn’t come with. But just an idea for creators out there. Works great and looks nice!

USED AROUND DOOR
The insulation was placed on door frame to seal it from cold and heat. Glue was not as much as expected but is still there in most places a year later.

Worked out Perfect!
This worked out perfect for my window application. The adhesive is considerably sticky so it adhered to the surface very well.

Disappointed ☹️
The foam is too light weight and fragile and the adhesive is not strong enough. I was expecting more of a memory foam density with adhesive strong enough to stick to an interior door frame.

Exactement ce que je voulais pour moins cher qu’en magasin sur rue.

Parfait pour mon projet

Used it for my backdoor that you could see light through the gaps in the sides. The back room holds heat way better now

Works good, the only issue is that one part of my door fits a bit more snuggly and has caused part of the tape to peel back. Could use a bit stronger adhesive perhaps? Or perhaps it was just too thick for my door in the area. Otherwise works great and has made a huge difference in the wind draft
