Can I spray closed-cell insulation on inside of brick wall ?
I live in South Louisiana and am remodeling a Ranch Style Brick Home. I have removed the drywall and have 2 x 4 studs, 1/2 ” impregnated sheathing, 2 1/4 ” dead space then brick and mortar.
If I remove the 1/2″ sheathing from the inside (easy to cut out) , this would give me 6 1/4 ” space to insulate. Could I spray the closed cell spray foam directly aganist the inside brick wall filling the wall cavity up to edge of 2 x 4 , then finish with new drywall? Would this create any future problems for walls?
