1926 Tudor basement finishing project
Our house is a 1926 Tudor located in Minneapolis. I am in the process of finishing the basement. Planned insulation is 2″ rigid (polyiso or XPS) with 2×4 stud wall. I am only air sealing the rim joist due to the fact my floor joist are half buried in concrete.
My question: there is not much clearance behind our boiler, so I was planning on leaving a void of insulation and stud wall behind it. There would have to be a void on the wall above the boiler as well, as the flue attaches to the chimney in that area. The boiler and water heater will be in an isolated mechanical room. Will this plan lead to any potential problems?
Thanks in advance.
