Hi All,
I Am renovating my basement. It is pretty dry to begin with. I live in Nova Scotia, Canada. Fairly cold winters, hot summers. My outside walls are studded. I want to insulate these walls. but the insulation touches the bare concrete foundation. I vapour barried the foundation walls and will then insulate and VB again before I put the gyproc up. So this will be
2 layers of VB or in order gyproc, VB insulation and VB againnext to the foundation.Now I am confused. I read in a forum that the first layer of VB (on the concrete foundation) can sweat, but my insulation would be dry. Should I seal the walls to prevent this. This would mean taking the VB down and sealing. Is this true? Will the VB sweat? The basement is pretty dry, but a little damp at times. Right now there is no heat at all. I will be hooking up 2 cast iron rads to heat the living area of the basement. Am I on the right track?
Another issue.
I have a sub floor, but it is water damaged in one small spot from years ago I would assume. I bought the house 15 months ago and is 65 years old. There has not been any water leakage and we have had plenty of rain storms so i think I am ok. I will repair /patch the water damaged floor. I plan on putting carpet down and I am for certain that there is no insulation under the subfloor. Can I buy an insulated type of underlay for the carpet to make up for no insulation under the subfloor.
Am I being paranoid about all of this? Am I on the right track with my walls. Will this be enough to keep my family warm in winter? I know I may need a dehumidifier, but am not sure. The foundation is in pretty good shape, but like I said it's a little moist at times, but there is no heat at all. I am hoping the cast iron rads will help with the small amounts of moisture.
Please advise
