what is its minimum thickness when compressed? I want to use it as a seal around a rear vent between a microwave and the wall opening.
Asked by: jackofalltrades
The material is about a 1/16 " thick, hollow with a 1/8th " air space cut in a quarter circle with a bit of a lip. it will squeeze together so there are two thicknesses of material being about 1/8 inch as the minimum. The same is true for the medium gap stuff; it is cut in a half circle (I used it to seal between the range and the counter without taking the paper off the adhesive).

I'd give it an excellent rating but the self-stick backing needs to have better adhesion. I would recommend cleaning the surface of whatever you're applying the weatherstripping to with rubbing alcohol.

Also noticed it dampened the sound (not totally diminshed) coming from a busy street. Saved me alot of money otherwise I would have to replace the windows.

I had tried a few products to see if I could seal the gap to keep the outside air out, either heat or cold depending on the season. I found this product and decided to give it a shot. I ordered a couple of packages not knowing how many I would need. I prepared the wood around the frame with a cloth and some rubbing alcohol. I lined the frame with the weatherstrip and then I also added another strip on the inside edge of the door. I was so impressed that it sealed the door perfectly for the first time since we have owned this home. Love this stuff. My husband was impressed with the quality of the product and the job I did on the door.

Rated 5 out of 5 by from Seals perfectly One of the reviews here incorrectly states that there is only 7' in the package. The weather stripping needs to be torn down the middle and then you have two long lengths of weather stripping. Make sure you clean the door jam before applying or it wont stick. If you're sealing a leak (and that's why you're buying this, right?) then there's probably a lot of buildup of dust and grim right where the tape needs to stick. I cleaned my jam until the paper towel no longer was brown from dust.

Rated 5 out of 5 by from Excellent solution I have already recommended this product since buying it last week! We installed a high quality dog door in a sliding patio door frame. The narrow dog-door panel is the full height of the sliding door, with a long thermal pane window above the small dog door at the bottom of the panel. Regardless of the good quality, it needed much more weatherstripping around the panel than the manufacturer provided!! This white weatherstripping is wonderful -- matches the white vinyl on the slider and dog door panel perfectly. Easy install -- pushed right into the edges where there were slightly variable width gaps. Very soft, pliable, easy to cut. Did a top-to-bottom door section in 2-3 minutes. And the result is no leakage whatsoever. Looks like a permanent solution and like an original part of the door.

Rated 5 out of 5 by from Good Product Good product. Have used for a number of years, but unfortunately local HD doesn't stock any longer so had to order on ship-to-store. Fortunately they still have it available this way.
