Cold air through pine floors

15 years ago

Hi!

We purchased a 100 year old house last year. Our basement has one radiator in it. That means that our large back room doesn't have any heat. We aren't interested in heating it either.

The problem is that we have old pine floors and no sub-floor. Cold air comes up through the floor in the living room. We live in a cold climate too.

Should we insulate between the floor joists in the basement? If so, how? Create a sub-floor? Tack carpet up between the ceiling joists? :)

Fiberglass and insulation supports.

The supports are just pieces of slightly springy steel wire longer than the clearance between the joist.

They bend slightly as you push them into place and they dig into the joists at each end slightly.

After installing the insulation you will need to put up a barrier to prevent air movement (fiberglass insulation is not very effective at that).

Even a layer of drywall will help.

Avoid anything that can burn though.

A ceiling covered with flammable material is asking for trouble.

If anything ever happen the flame spread can be VERY FAST.
