I am getting ready to install my floor and have some questions for the group:
- What do people typically use to fill the valleys of the corrugated metal floor? Looks like a rib height of approx 5/16" (does anyone know if this is accurate?) but I couldn't find any plywood to match that profile so I currently don't have anything to put there. Which leads to my next question....
- What would be the result if I just left the valleys empty, and adhered 1" XPS directly to the metal ribs, followed by 1/2" (stained) birch plywood, with a vinyl floor on top? Would the XPS support that? What would be the impact to thermal insulation?
