Hi!
I am in Saskatchewan, Canada (the cold part of Canada). I am in the process of preparing for finishing the basement of our 9 year old house. I would like you pro's to review my design for construction of my exterior basement wall finish. Also the fire blocking....
There are no signs of water problems and there is a working system of exterior drain tile connected to a sump pump.
I want to insulate the exterior walls with R20 and put some insulation on the concrete floor to keep the feet warm. There is no existing exterior insulation, the basement is about 9ft high between concrete floor and bottom of the floor joists. Grade is about 6ft above the concrete basement floor.
I want to use rigid XPS foam for insulation. 2" straight on the wall and extended into rim joists. Then a 2x4 wall on top of 1" foam of the floor, spaced about 1/2" from the foam on the concrete wall (walls are not flat).
Another 2" foam in between the studs of the 2x4 wall, no vapour barrier. A suspended ceiling and mineral whool in between floor joists will be added.
Any comments, problems or ideas for improvement?
thanks a lot!
