Trisiki Weather Stripping Door Seal Strip, Strong Adhesive, Lightproof, Noise-Reduction, Weatherproof Foam Tape Insulation for Sliding Door, Front Door Frame, Windows (1/2 in x 1/4 in x 26Ft)

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.

This item was very easy to install. It definitely cut off the draft. Perfect thickness, and stays where you place it.

It does the job. It is a very fast adhesive. Place it exactly where you want it or you are going to remove the weather stripping and your paint just trying to readjust. Also make sure you measure correctly. My door frame is crooked so the size I bought only fit part of it. It will keep out the cold, heat and the large bugs that want to become a part of your life.

Works great and sticks well

Easy to peel weather stripping-easy to install and very thick to keep the drafty doors sealed properly-I recommend’

It’s decent for the price /helps in some voice reduction/

Good adhesion, nice firm seal.

I don't know about long term. However, the adhesive is insanely sticky and the material is clearly water resistant. I used it as a triple seal with the center seal opposite of the outer seals in the middle. It held the water out from a serious rain storm. Then continued rain for days after. If it holds long term then it was definitely worth the purchase.
