Hi, I'm renovating my house and the basement floor had no insulation at all. I removed the old 2x3 and plywood floor and installed R5 blue rigid foam with tuck tape. Now, I'm wondering if I should install 2 layers of plywood or 1x3 accross the basement and then a plywood. What's your thoughts on this DIYers? via /r/DIY https://ift.tt/2Mc39gm
