As I’ve mentioned a few times, we are insulating our house with spray foam. We decided on a closed cell spray foam, because it provides more insulating value per inch than an open cell.
The insulation was installed about a month ago, and we could immediately feel that our house was warmer. In fact, it’s been cold for about a month (in the 20s at night) and until our heat was turned on a few days ago, we were able to completely heat our basement with this tiny space heater. That shows how effective the spray foam is at keeping us warm!
I was also impressed by how strong it is – if you punch it, it hurts your hand. Also, within 24 hours of it curing, you could not smell it. A lot of people are concerned of off-gasing of chemicals of spray foam, but with our closed-cell product, it really is not off-gasing hardly anything that we can tell. Conversely, a friend recently insulated with an open cell spray foam product, and even two weeks later the rooms still had an overwhelming smell.
