insulating a half finished basement

Post by Gris » Mon Jan 13, 2020 5:16 pm

Hey there. Have an interesting question. The house was built in 1960 with block foundation, the basement is half in ground and half above. The original owners had painted the block or glued paneling on.

All interior walls and floor are finished.

I am wanting to insulate the exterior walls, as the area is used is living space.

Do I need to remove the sub floor (currently on 2x4 joists/sleepers) to attach my 2” rigid foam? Can I cut a 2” portion back from the exterior walls allowing the insulation to fit from the ground to the upper floor joists. Then add 2x4 wall attached to current sub floor?

cheers

You could really just run the foam to the sub floor and then frame the walls on top of it as well IMO.
