If you're looking to keep your home warm -- a good thing to do is to add insulation. A great place to add it is your basement. If you have a heated basement, only the walls need to be insulated, but the ceiling may also be insulated for noise control between floors. When floor space or wall depth is an issue, rigid foam insulation can be installed over furring strips. Their notched-design system makes installation easy?panels butt together to form a tight barrier against air infiltration and energy loss. Owens Corning has a great product called INSULPINK foam insulation board for this purpose. You can learn more at www.insulateandsave.com .
