Careful what you wish for... LOL supposed to get to 25°f today, its only up to 5, the sun is setting and I'm still waiting...
We did foam insulation in our old leaky house. took all the walls out, had a company come in and foam it. because we were still living in the basement, we did half the upstairs at a time. First time they came in and sprayed this nasty smelling stuff.. but it went away after a day. The second time they sprayed corbond and it was odorless... compared to the other type. because the house is 70 years old, its far from air tight but sure doesn't feel drafty anymore.
We are building a 40x60 two story shop this summer, and are looking in to SIP pannels. It will be air tight on the second level so we will be putting in some ERV systems on both levels to keep any smells out of the second story.
