Sub slab insulation with Superior Walls
Does anyone have a solution for how to insulate below a basement slab when using Superior Walls for a basement? The closest thing I could find was this link here:
I’m not exactly sure how they dealt with the edge near the walls. Is the gravel base graded at different levels to accommodate the different levels of foam?
Is the loss of R value in the floor near the wall a big enough deal to worry about?
