My house is about 40 years old and was build according to Canada Mortgage and Housing Corporation Guidelines. A recent water heater mishap caused me to have the carpet (ughh) ripped out of the basement (yay!!). The carpet had been laid (with cheap underlay) directly on the concrete. The walls have some kind of foil sheets, no batting, for insulation, finished with "panelling", not real wood but fibre board with a laminate or veneer that looks sort of like wood. I have two quesitons:
1) Is it really necessary to put in a subfloor? I want to put 5/8" plywood, nailed directly into the concrete, and paint it.
2) Should I take down the panels and put in pick insulation or is this foil stuff okay? I understand gyproc is not recommended for basements due to air quality issues.
The basement is not too damp - especially now that the capret is gone. There is an exhaust fan in a full bathroom there, and an automatic dehumidifier which does not go "all out" except in the summer.
It's not really warm, but I live on an island in the middle of the North Atlantic so I don't expect it to be.
I am on a strict budget with no wiggle room at all. My teenaged sons are keen to turn it into what we used to call a "pad". I want them to be comfortable, but no so comfortable they never move out..
