Crawlspace Insulation: Floor and/or Walls
Looking to have spray foam applied in crawlspace. 1950s home with dirt floor crawl space.
Main concern with insulating walls is that poly vapor barrier provides little insulating value, and a lot of heat will be lost through the vapor barrier into the ground. How much of an issue is this? Will the floors in the house be noticeably warmer in the winter if we insulate the walls but not the floors?
Other suggestions? Thanks for any help!
