Hi, I was wondering if that spray foam insulation that comes in cans is
considered safe. When that kind of insulation first came out I think about
20 years ago, a friend of mine had his whole house done, only to learn that
the product outgassed formaldehyde, and had to take the house down to the
studs. Do the new products now still have that problem? I just want to fill
some holes and cracks to keep out cold air.
Thanks,
Chas
