Insulation Services: What Is Knee Wall Insulation?
Insulation services with Star Companies, Inc. answers the question: what is a knee wall? A knee wall is an interior wall that has living space on one side of the wall and attic space on the other side. Historically, knee walls were short walls around knee level but in modern construction, knee walls can be as tall as the interior space up to 12-15 feet tall in larger homes.
This presents a problem for conditioning the living space because not only is there attic space above the ceiling, now there is attic space behind the walls. If you have a walk-in attic, a split-level home, cape cod style home, or a small door in the wall to access your attic, you have knee walls in your home.
Insulation services for knee walls requires experience and quality workmanship to properly insulate these walls. Foam board insulation is the most common use to properly insulate and air seal knee walls. At minimum, battling insulation in between each stud cavity is required. However, only installing fiberglass insulation in the knee wall does not stop the unconditioned air in the attic from heating or cooling the wall, which in turn permeates in to the living space.
Our insulation services makes sure there is a permanent solution to your energy needs. Installing rigid foam board to the face of the stud, then using spray foam to air seal the wall effectively creates a closed system that directly impacts your energy usage and your wallet. Our expert insulation services can help determine if your knee walls have enough intact and sufficient insulation, or if your home requires more.
