Heavy Duty Weather Stripping Door Seal 52 FT Bulk Pack, 1/2" Wide x 1/4" Thick Foam Tape for Whole House Front Door, Window Frame, Self Adhesive Closed Cell, Black (2 Rolls x 26 Ft Each)

This weatherstripping is extremely solid and well made. I used it to seal a DIY air purifier, and the adhesive strength is excellent. Before applying it, I wiped the surface down with isopropyl alcohol to ensure good adhesion, and once it was on, it stayed firmly in place. The material itself is flexible and compresses well. The adhesive is very strong, almost too strong. When I installed it on a door, I made a mistake in how I oriented it. Because of the direction of force, it ended up pulling against the surface instead of being compressed, and it actually ripped some paint off the door. That was user error, not a defect in the product, but it is something to be very careful about. Make sure you install it so the door compresses the weatherstripping rather than pulling on it, otherwise you risk damaging paint or finishes. Another thing to be aware of is the smell. When I first installed it, there was a strong chemical odor that lasted close to a week. You will want good ventilation during that initial period. I cannot really comment on the exact thermal insulation performance, since I did not measure temperature changes. My goals were to block light from the hallway, since I am a light-sensitive sleeper, and to reduce airflow so I could test my air purifier in a more sealed room. For both of those use cases, it worked very well. Overall, this is a very high-quality, aggressive weatherstripping with excellent adhesion. Just be mindful during installation and ventilate well at first.

I bought this to seal up a few spots on a drafty door. Seems really durable and so far is working great.

Sticks well

This is as described. It ended up being slightly to thick for our door. It is flexible & easy to install. It did help with noise & draft protection. We just could not get the door to close all the way because of the thickness. We ended up having to pull it all off. I did not see a thinner version so we are still ISO something similar but thinner.

Works as intended. Definitely helped with the cold draft coming through the sides of the front door.

For me the stripping could have been stickier other wise it was a great value for the price

Easy to apply and works great

Adhesive is strong and the insulation protects against drafts and noise. easy to cut.

el empaque contiene un adhesivo de pésima calidad solo se viente como si el empaque estuviera totalmente chicloso pero sin capacidad de adherencia y no se puede poner una cinta doble cara ya que no el adhesivo en el empaque es una calidad no mala mas que mala

Its great, a little bit thicker than I wanted, the paper backing sometimes tears while its being removed which is a bit annoying

The door strip good quality specially the adhesive is a strong

Good product

These guys used poor quality materials, which resulted in a poor seal. Highly not recommended.
