Insulation: what type to use?

Post by Giz » Fri Nov 16, 2018 5:46 pm

My house will built in 1980. I have a basement that is kept warm from the boiler that provides baseboard heat for the first and second floors above the basement. This is not a crawl space. The floor joists between the basement and the first floor are exposed and not insulated. What type of insulation should I use? Rolled fiberglass or paper covered batts? If paper covered batts, how should they be installed (paper side up towards the flooring or paper side down towards the basement floor) Thanks!

So why are you insulating the floor ( ceiling joists)

I am considering installing insulation between the floor joists in the basement so as to prevent cold air from the basement from leaking into the first floor. Yes, I realize cold air sinks and hot air rises. However, there are differences in pressure levels between the floors, correct? I live in New Hampshire.

You could be getting a little cold from down there if it is considerably cooler then the main floor. I would use the rolled fibreglass IMO.
