Homeowners were insulating their attic to lower their cooling and heating bills. Since the spray foam is being left exposed here, a fire retardant is sprayed on top of the foam.
This homeowner has an older farmhouse, which had a very small crawl space and a laid stone basement. The walls were sprayed with closed cell spray foam to grade (2 feet) with 2 inches of closed cell spray foam as well as sealing the rim joists to make this home much more comfortable for the homeowners.
