    I am talking about the pink fiberglass insulation. My crawlspace has a concrete wall, and on top of that is the framing of the house. This framing is about 12 inches high till I get to the floor joice's. I want to insulate this section (the wood part). My question is this: if I was to buy a package of insulation, and lay the pieces end to end, how long would one package last, in feet? My crawlspace perimeter is 140 feet, and I want to know how many packages of insulation I need. I will fit the insulation between the studs, and staple plastic over it.

    Thanks.

    The bundles will tell you how much linear feet you get with each one. So if you need insulation to fit a 16" inch wide bay that is 12 inches tall in a 2x4 wall thickness....that is what you need to measure for.

    So if your wall is 1 foot tall....how many pieces will you need at 16 inches wide? Count the bays.
    That will be your linear feet.:banana:

    Hope this makes sense, if not, feel free to ask again.:)

    Many of the insulation packages are sold in different lengths
    Some are in 4' lenghts - 10-11 per pkg
    Some in 40' rolls
    So it depends upon the Rvalue you want

    Do you have a dirt floor or concrte in the crawl space?
    If dirt it should be covered w/plastic to prevent keep moisture out
