Actually I do want to insulate my house too. It's been really drafty this year. We freeze our butts off even when the thermostat says 71. Maybe I should get another thermostat to check its accuracy.../shrug.
I tore my carpet and pad out a couple years ago and refinished the original wood floors. They look great but feel like ice, and air comes in here and there at cracks.
Anyone ever insulated your floor above your crawlspace? I think it would help a ton. We blew in a foot of insulation into our cieling / roof a year ago, but its still cold. I just worry about moisture and if our crawlspace will get too cold and freeze pipes more readily.
If we save energy, we can lessen our carbon footprints!
I just don't want to freeze my butt off every night.
Careful with that... the previous owner did that to the house I bought, insulation and vapor-barrier under the floor in my partial dug-out crawlspace/basement. It was separating two "conditioned spaces", which is bad, and it became a moisture trap. The insulation was wet, puddles in the plastic. It was gross. I ripped it all out.
I believe the proper way if your crawlspace/basement is "conditioned space" - i.e. heated in the winter (you have pipes that could freeze etc), then you want to insulate around the perimeter of your foundation to keep the crawlspace warmer.
If the crawlspace is not "conditioned", you want to insulate the floor/plumbing, and then ventilate the crawlspace so moisture can escape and it stays the same temperature as outside.
Sealing up any drafty spots can help a lot too. We have an addition which is one room downstairs and one room up, and is exposed on 3 sides. It's fine most of the time but if it's cold and windy, the temps start dropping. It has a bay window that is junk, I've sealed it up the best I can but it really needs to be replaced.
