Knee Wall Insulation in Sacramento

As one of the biggest sources of energy loss in homes, the attic needs to be properly insulated. Do you need more attic insulation for your home in the Sacramento, California area? Never ask “Where can I find attic knee wall insulation installers near me?” again! Contact Gold Star Insulation or keep reading to learn more about attic and knee wall insulation.

Insulating Knee Walls & Other Spaces in the Attic

If you’re insulating an attic, the knee walls are important. They are short walls (usually no more than 3 feet high), used to support the rafters in roof construction, with attic space behind them. Attic knee walls are found in many older houses, where the ceiling on the top floor is an attic or there is a dormer window.

According to the Oak Ridge National Laboratory, the open joist ends below the knee wall should be sealed with rigid foam, high-density cellulose or batt insulation. The knee wall (and attic floor) in the attic space behind should be insulated to the recommended levels. You can also insulate and air seal the rafter space along the sloped ceiling of the knee wall space.

Insulation should also be installed in between the studs of knee walls. In addition to knee walls, you should also insulate:

Finished attics

Unfinished attic spaces

  • Between and over floor joists (to seal off living spaces below)
  • Attic access door
