What is the proper Attic Insulation vapor barrier orientation?
If you're installing insulation yourself, remember these guidelines when using a vapor barrier: * Always place the vapor barrier towards the warm side of the insulated area - facing downward on the attic floor or to the interior side of the wall. * When adding a second layer of insulation to an attic, do NOT add a second vapor barrier - this can trap moisture inside the first layer. Use loose-fill or unfaced batts or blankets; if only faced batts are available, cut facing every few inches to allow air to pass through. * If the vapor barrier tears during installation, tape it tightly. * If you have a crawlspace, add polyethylene vapor barrier on the floor of the area to reduce condensation from ground moisture.

What kind of insulation is best for basement walls?
The best insulation to use is spray foam, although it is an expensive option. Another option that is less expensive is 1" rigid foam board.

Avoid using batt insulation w/vapor barrier in basement applications as condensation may occur which will encourage mould growth.
