A. MAZ. ING. Our 50's wooden double hung bow window is SUPER drafty. We don't have the money to replace it right now, so we are weatherproofing to hold us over. Before using this product I put an indoor thermometer by the window. Then I checked it after, it went up 12 DEGREES!!!!!!!! That not only speaks to the horrible quality of our windows, but the amazingness of this product. Our living room already feels so much warmer.

I love this stuff! I live in an area with extreme temperatures through the year, as well as high winds. I love the house, but it was built in the fifties and is pretty drafty, which can up the heating and cooling bills quite a bit. I can just apply this stuff over the window seams and it's like a brand new window! I have it on every window and all along the door that leads to the garage (in the gaps where the door doesn't meet the frame well). In spring and fall, I just remove it if I want to open up the windows, and when summer's heat is on, I just reapply - I can reapply it a few times before it loses its tack. I've gone through almost three rolls in two years, but this stuff pays for itself and then some.

I am so sensitive to drafts that I can feel cold air in a room with my nose as soon as I enter it. This stuff works amazingly well!

Here is what I wish someone would have told me when I was looking to buy this. You do not need vision to apply this. I am totally blind, and I am able to do this without any site at all.

It feels like silly putty. All you need to do is press the stuff in the gaps, and the noise and the cold draught go away.

This is easier than using plastic on the windows because it does not require the use of tape, a hairdryer, a chair to stand on when you have to reach the high places, or anything else. It requires the ability to use fingertips to press it where you need it, and that's it.

If I notice a draught in my house, I am uncomfortable and cannot get anything done. I am extremely sensitive and aware of this. After someone pressure washed my house, I think it might have dislodged a little bit of this at the bottom of my door. There was literally a quarter of an inch that may have a come loose. I was distracted by the draft for days until I figured it out. All I had to do was use my finger to push it back in to the area and that was it.

It is easy to remove. So if you are renting a house, this is perfect. Just grab hold of it and begin dislodging it from wherever you have it and it will release itself.

This is my first review ever, but I actually thought it was important enough because I just used the stuff after owning it for four years, and I still love it today.

The coldest it gets is 28 degrees in the winter. But it is 70 degrees outside now, and I still can feel a draught when it comes through the door at the bottom. So it does not matter what temperature it is outside, it matters that I can seal the draught from coming in. I will shiver outside if it is 70 degrees with the slightest bit of wind.

This is what I would have wanted to read when I was doing my homework. I hope this helps you too.

We have a front porch with 10 ancient wood windows that rattle in the wind and leak lots of air in the winter. This stuff takes a little bit of time to install, but once stuffed around the edges of all the windows (and other places where air whistles through), it does a nice job of keeping in the warm air and keeping out the cold.

It is easy to apply -- kind of like soft clay -- and easy to remove come spring time. Choose one, two, or three "ropes" worth of thickness, depending on the size of the gap, and stuff into place. It is also a LOT cheaper than buying new windows.

Another huge plus: Does not degas awful fumes like the many removable silicone caulking products on the market.

Bottom-line: It's cheap, easy to apply (though it will take a long time if you have many windows!), and easy to remove in the spring. It stays pliable, so you could theoretically reuse it, but it's cheap enough that we just buy a fresh box each year rather than trying to painfully re-roll it and save it. Recommended for keeping out drafts without buying new windows.

This stuff doesn't look attractive at all and is slightly fragile or crumbly to handle. However, it definitely has insulated the window in my bedroom that was always freezing and made the room feel like an icebox.

When applying, i felt for where the draft was coming in and pressed it well into the cracks. The cold draft doesn't get in anywhere near as much as it used to. Also less noise gets in, and we live by a very noisy main street in Los Angeles.
Glad I bought this, it's a good value and saves on heating. Use this in conjuction with a good space heater for best results in winter. I can also easily remove this whenever we move out, so it's great for apartments . 4 stars because it looks so ugly and is a little crumbly.
