Basement wall insulation and wall build
I’m insulating and framing a basement wall that is 24 feet long. A 4in PVC sewer pipe runs horizontally about 15 feet down the top of the wall and then drops vertically down to sewage line and my water meter. The vertical pipe is not near the corner it’s about 3-4 feet from corner. I want to insulate with 1 inch rigid foam and then build 2×4 wall. Most recommend building a wall in front of pipe but the room is very small, my wall would be coming out 8 1/2in. Is there a way to notch the wall and save room. How much can I notch the wood studs? I could use blocking to build under the pipe but then finishing with drywall would become complicated.
