This is a great product for filling smaller gaps. For really large ones I would use fiberglass insulation. We used several cans of this foam sealant when installing new windows and doors. The big caution is this: it can drip on surfaces where you don’t want it, so if you are using it indoors it’s smart to cover the floor with cardboard. At one point we forgot to cover the floor and some foam hit the tile. Trying to remove it when wet is a big mistake. It smears and makes the situation worse. It is better to wait until the foam is hard and dry, and then carefully scrape it up. When using it outside (as shown in the photo) we were less concerned with covering surfaces. Some foam dripped in three places on the pavement and we scraped it up, but if the concrete had been rather rough we would have covered it because the foam leaves traces behind due to the uneven texture. Once the foam is dry it is easy to trim away excess. Before you start your project, take a look around your house to see if you have any holes that need filling, because once you open the can either use it all or toss it. We had some left over and used it to fill some annoying small gaps and holes. Overall this is a great product and I would recommend it.

Rated 5.0 out of 5.0 by john Good Product, medium expansion
Worked well, I used it to fill a door I made for a strange size opening. It expands less then the Red Can of expanding foam

The product is good, but the can/applicator kept leaking from the nozzle and towards the end of the bottle the nozzle broke off the bottle. I have used this product before and have not had a problem. I think this one was defective. I does seal very well!

Works far better than fiberglass at stopping all air from coming in. Just be careful of not overfilling cavities so you don't make a huge mess.

Rated 4.0 out of 5.0 by BitNybbler Well worth the extra price
We normally use the much less expensive red can version.
When doing doors, windows, or anywhere excessive expansion will cause a bad fit, the blue can version is far better.

Rated 3.0 out of 5.0 by GABBB Good product for around windows and doors, but has its issues
I love expanding foam insulation, but my main issue with this incarnation is that while it is slow expanding, it seems to expand overly too much. Alternately, I am not good at judging how much I need to spray under a window sill or next to a window. It's not that the foam distorts the frame when it expands, but it just seems to keep coming out of the opening.
My caveat would be to use it carefully. The bummer is that once you start spraying, you can't stop and come back later with the same can. That means you can't spray a little...wait 10 minutes to see how it expands, and then spray again. So be careful with this. It won't distort windows, but if you put too much in, it will be like the expanding foam monster just paid you a visit.
