I want to insulate the cinder block walls in my crawl spaces, I have three separate 10x10 cubes of crawl spaces.
I was told by basement Systems that i can just use spray foam as the 'glue' on the cinder block and then use the foam board for insulation. The spray foam with make it stick, but that does not sound right to me.
I found concrete screws that I could screw i the foam board with, and then i could seal the gaps with spray foam, that is what I planned on doing.
What is the recommend way to insulate the crawl space walls? Thanks
