Can I put foam board insulation on top of one floor and lay another floor on top of it?
I have a enclosed porch that I am trying not to crawl under to put insulation. I also want to make the floor level. So I want to know if I put foam board insulation on top of the old floor and level the new floor, will the new floor keep the cold out?
