Rated 3 out of 5Â by TomTheToolman Worse than opening a can of worms!
I replaced 7 windows and the door wall, all needing to be reinsulated. This stuff is the best product for the job but having not used it previously, I was on the 3rd can before I learned how to control the monster. I recommend you begin by applying much less than you think you'll need. You can always add more after the initial expansion stops, but if you put too much into the gap it will continue to ooze out for 30 minutes or more and cause a god-awful mess on all adjacent surfaces. I also recommend you mask where possible and buy a quart of Acetone for cleanup, it's the only thing that is a solvent, and then only before setting up! Be careful what you apply acetone to, it's nail polish remover! Oh, and wear disposable gloves. I had some of this set up on my hands and like the directions on the can say, cured material on the skin will have to wear off. I had a yellow fungus-like blob on my hands for over a week. Beware.

Rated 5 out of 5Â by JayM Read and follow directions for great results
I'm going to guess those writing negative reviews either just got a bad can - it happens - or didnt follow directions or expected something from this that it was never meant for.
I used this product on every window in my house - 20 in total - and it worked wonderfully everywhere. It can get a little messy but keep a rag with acetone handy and it cleans up great. Also, if you get overage on windowframes resist the urge to wipe it immediately. Better to let it cure fully, then it will seperate easier from the frame and you can trim it cleaner. If you wipe it immediately you'll create a smearing mess.
Also make sure the outside temperature is above 40*. If it's less than that the side exposed to the exterior may not expand fully and you wont get the full benefit of it's insulating properties.
Read and follow directions and you'll be just fine.
One suggestion - a flexible extension hose would be great for areas that are tight to a ceiling, since the can typically has to be used upside down. Otherwise love the product, and my energy bills do even more. Otherwise, you can take any small hose, heat up the end slightly to fit it over the nozzle, and you're good to go.

Can only use one time. Due to the delivery system design it clogs no matter what you try to do.
- Leave product in tube and cut for next use = does not work next time
- Take off clear handle/hose and spray clean with brake cleaner and shoot compressed air to really clean out = does not work next time
Ends up being a huge waste of money unless you intend to utilize the entire product right when it is first used.
The company needs to talk with the can vendor or if Dow is also making the can they need to re-design!
Will find alternative products to use.

Rated 4 out of 5Â by Wjs58 Insulating Foam
Does exactly what it should by filling gaps around doors and windows without expanding too much. I wish there was an easy way to regulate how much you squirt in the gap so as to not overfill and have to waste half. By the time I got to the forth can I was getting better.

It was time to replace the caulk around the windows. When I took the old caulk off, I found that the contractor had not filled in the voids under the siding and last winter we felt cold air coming in. So I bought this foam sealant to fill in the voids. It has easy to use.
