|More or less 4" of rigid insulation!|
Anyway, Philip was instrumental in helping level the basement sand and installing the terrafoam rigid insulation that is 6" in places and 2" in others, where it covers some plumbing. I'm not sure I would recommend 4" shiplap Terrafoam, as the shiplap was barely a shiplap and it only did that on the long edges. I think we should have used 2 layers of 2" rigid that were properly shiplapped.
Now I have to go back for some night time poly laying and rebar-tying. Fun never stops! I hope my car headlights light up the basement!
