Did some more work today, finished the floor Well, the unfinished floor, it'll have a solid peice of linoleum for the finished floor.
The floor is constructed with 3/8" ply on the bottom, 1/2" rigid foam insulation between that and the joists, R13 between the joists, and 3/4" plywood top, all screwed together with 1-5/8" gold screws, except the framing, with 3" screws.
One little injury, screwgun slipped and I punched a philips shaped hole in my left pointer finger. These kinds of things happen on a daily basis.
