Subfloor insulation at 8,500 feet in Colorado?
I’m building a studio/shed on our property. Using local rock under the beam supports, basic plywood construction. Wondered what the most efficient and simple insulation should be between the joists and under the subfloor?
My research has yielded A LOT of varying opinions and recommendations. Spray on… Polyiso boards… etc.
Love to get some suggestions from folks at GBA.
