Weatherstrip, 45 ft, Gray

For three years the windows in my apartment have bled cold air. I turned to the Internet and discovered a This Old House and a video about this product. It has worked wonders by stopping all the leaking air. Follow the directions on the packaging and you'll have no issues. This is simple to use and stays in place without issue.

I used this to reduce road noise coming through my front door. The insulation is just thick enough to give a really good seal if the door gap is around 3/16 to 1/16 of an inch. The stripping is fabric covered and the adhesive is very grippy. My door now closes snugly and cars are a a dull roar. Great stuff.

Used as a crack filler. Worked excellent and blended right in

I’m renting for the first time in years, and the place is... drafty, to say the least. The windows have gaps between them and their casement, and I was debating this versus ugly sheets of plastic over them so that my heating bills aren’t worse than they’d be already in a New England winter. Since I can’t fix the real problem, and it would be unreasonable to expect my landlord to, I found this and the plastic sheeting, and decided to test this out first. It’s a dry putty caulk, basically. Easy-ish to put on, supposedly easy to remove (I’ll update in spring if needed). It is like a dry version of silly putty, extruded into joined ropes. At first I thought, “why???”, but it makes sense, really; most of my gaps just need one strand, but the sizable gap between the window and sill at the bottom (I don’t remember what that part is really called) required three to fill it to my satisfaction, in a sort of triangular configuration that was surprisingly easy to achieve. Yes, it’s a pain to tear them apart; be patient and go slow, and it works fine. Mine wasn’t melted or dried out—and the box says it WON’T dry out—so I was able to cover all the gaps on the window next to my small kitchen table. I sit here for work and for food, and believe me, it was a lot chillier before I did this. I’m going to have to move all the plants from the other window to do it next, but it’s worth it. Then the upstairs; the living room has plastic from prior tenants (a big clue that there is a problem), but I hate both it and not being able to use the blinds, so I am considering replacing with this instead. Could do both, if it’s really bad, but my heat doesn’t run constantly anymore, between this and some weatherstripping on the drafty doors, so I’m going to wait and see about that for now. I feel fine sitting next to the window right now, though it’s rather cold outside, so I suspect this will be enough. The mixed reviews made me wonder whether to go for it or not; I say, if you get a good batch like I did, a nice, normal roll, it’s totally worth it. I can do all eight double windows, I think, with this one roll... and if not, it’s pretty inexpensive to reorder. I was dreading fussing with the plastic, and now it looks like I don’t have to!!!

I like that it was easy to use and removed without damaging the wood frame.

Such a useful product. I used it to plug up air gaps in tight spaces. No mess like ordinary caulking to wipe up.

If you are feeling a draft from the cracks of your window frames you block the crack with this product. It is easy to put on and take off when springs finally comes. My parents bought a beautiful old home and we used this my whole childhood. I had to use it in my current home until I replaced all the windows. This roll I bought for a friend in assisted living. They get cold from the drafty windows.. $5 stopped that and there is some left for another,her time. It is so easy to use. I was doing ,y own bedroom window at age 7. What you save in heat loss more than pays the cost of the product!

This string caulk is great. I first used it around the base of the toilet in our guest bath. So easy and less messy than a caulk gun.
