I just moved into a 3 level home with a crawl space under the entry,kitchen and dinning rooms. Living in Minnesota the floor gets cold being there is no heat getting to the crawl space. Would it help to insulate the floor from the crawl space? If so what would I use.

Thanks Cory

I'm working on a similar situation. Have you checked the US Dept of Energy and manufacturers' websites for ideas?

Do you have a slab or gravel in crawlspace?

I'm on gravel and don't intend to use the space for anything, not even storage.

In my situation I'm insulating the exterior walls. Insulating the floor overhead would require more square feet of insulation. Also my ducts and plumbing hang under the joists. I plan to line the crawlspace walls with heavy 6 mil plastic to keep out moisture (the floor is already lined). I'm thinking of pushing flashing under the sill plate and bending down over plastic liner to keep out termites. I need to talk to an inspector to see if that's a good idea. I plan to use 8 ft faced fiberglass batts 23 inch wide, with the face to the open space to limit moisture (exposed fiberglass against plastic). I plan to tuck one end up in the joists and let the other lay on the crawlspace floor. I'll use the wider batts so I can slit them and use friction against the joists to hold them up. I may need to figure a better way to hold them up.

This is one solution - I'm not saying its the best.

r 20 insulation batts inbetween the joists.this will help to keep the floor a lttle warmer. also you can put styrofoam insulation of 1 and a half inch (r7.5)down from the top of the concrete about 2 to 4 feet down to block the colder surface ground temperatures, as the lower ground temperatures are about 50 to 57 degrees.

the crawl space should not freeze without heat unless you leave the crawlspace vents open all winter.(the ground will actually heat your crawlspace to the 40 to 50 degrees.)
