What is a Knee Wall? A Knee Wall can be defined as a short wall usually less than three feet in height. They are often found in homes with finished attics and built to connect to the sloping roof. The Knee Wall serves as a short, solid wall in the finished attic. Installing an Attic Access Door into the Knee Wall allows access to the space behind the Knee Wall. The space behind the knee wall makes a great storage area.
Air leakage from an un-insulated Knee Wall Attic Access Door can cause heat to transfer from the attic into the living quarters in the summer, and from the living quarters to the attic in the winter. In order to avoid this heat transfer, consider installing an Energy Shield II Attic Access Door Cover. It will help to reduce your heating and cooling costs by sealing off the opening in your Attic Access Door.
The Energy Shield II attaches to attic side of the Knee Wall Framework. It has a zippered opening in which you un-zip to gain access to the attic. It installs easily in minutes.
Service Partners has standard sizes available: 24” X 48” for a Knee Wall Door, and 24”x 80” for a Full Size Door.
