Basement walls, XPS plus rockwool
I live in Zone 5 on the Maine coast. The top 2 feet of my basement is above grade. Are there any issues with placing R15 Rockwool over 2″ of XPS?
I currently have 2″ XPS affixed to my basement walls, seams all taped. I built a 2×4 stud wall against the XPS. I plan to fill the stud cavity with R15 mineral wool, either the Rockwool product or the Owens Corning product. Are there any problems with this? No leaks in the basement, I run a dehumidifier in the summer and I will have heat in the basement (although it may be infrequently ran).
