My shop is a 12x16 shed. The floor is 3/4" tongue and groove sheets over 2x6 joists at 16" on centers. In the winter the floor gets very very cold even when I leave my heater on 24/7. So today I was at Lowe's and ordered some Dow XPS 1" UtilityFit insulation boards with an R value of 5. I plan to put that on top of my current floor and then another layer of 3/4" tongue and groove over that. Basically the 1" XPS insulation boards will be sandwiched between 3/4" flooring.
The XPS boards have a compression rating of 15 psi. Is that sufficient for my cabinet table saw, bandsaw, drill press and more importantly, my Robust American Beauty lathe (approx. 800 pounds)?
The flooring I ordered is 23/32 CAT PS2-10 Tongue and Groove OSB. Was this a good choice for a floor, or is plywood a better choice?
Any suggestions on what to cover it with? I was thinking outdoor deck paint.
Delivery is scheduled for Thursday so I have a couple days to make changes if needed.
Thanks.
