I’ve received several quotes for spray foam insulation and they vary quite a bit. Are there different types?
Yes. There are different densities available. There are even “do-it-yourself” kits with a very basic foam. Lower density foams have less insulating value and more open cell content. Continental Insulation recommends 2 lb closed cell foam. It is more expensive at the time of construction but the payback far outweighs the additional investment. I am interested in having spray foam insulation installed in my cold room. I’ve been told that if I put a special paint on it that it doesn’t need any other covering to meet building code. Is that true? No. In order to meet building code, spray foam insulation must be covered with a thermal barrier. There is no paint or coating currently suitable for that requirement. A thermal barrier is a material which slows the transfer of heat. The test for any thermal barrier is to put a heat source on one side and measure the temperature rise on the other side. Any material like paint will transfer the heat almost immediately. Using any type of paint will n
