When insulating a heated basement, only the walls need to be insulated, but the ceiling may also be insulated for noise control between floors. Either Kraft paper-faced or unfaced exterior wall insulation can be used to insulate basement walls with existing or added 2x4 wall studs. Here are some tips for the project:
- Prior to insulating a basement, all foundation walls should be checked for water leakage and corrective action taken.
- The band joist should be caulked and sealed to prevent air infiltration at the construction joints and around all penetrations such as plumbing, electrical lines, and heat/AC and dryer vents.
- Faced insulation should be placed between the studs with the vapor retarder facing the interior of the room.
- For the band joist, use unfaced cut-to-fit pieces of insulation and place them snugly into the space.
- Kraft paper facing is flammable and cannot be left exposed. An interior finish material, such as drywall, should be installed as soon as the insulation is in place.
