Insulating A Basement
Proper basement insulation is very important because an uninsulated basement can account for as much as 25 percent of a home's total heat loss.
Unframed exterior basement walls should be insulated with blanket insulation, which can be installed horizontally or vertically. Typically, the blanket is held against the sill plate at the top of the basement wall with furring strips. In addition to the furring strips, you will need patch tape. Depending on the installation method you choose, possibly a nail gun and special fasteners for driving into concrete or cinder blocks. If you need a nail gun, be sure you become completely familiar with its operation before using it.
It's a good idea to wear a work helmet when installing basement insulation. Be careful around exposed nails and exposed framing such as ceiling and floor joists.
