"Super Knee Wall" Insulation- Malverne, NY

When our home comfort specialist arrived at a home in Malverne, NY it was easy to see a poorly insulated knee wall was causing comfort concerns. A knee wall space is created when a finished room is built within a sloped roof. When this area isn’t properly insulated it results in the upper level, the ceiling of the lower level, and the knee wall to be very cold in winter and hot in the summer. The knee wall is then not suitable for storage. Triple H added baffles in each rafter bay to ensure proper airflow before adding the insulation. Then they added fiberglass insulation before covering it with SilverGlo foam board insulation. SilverGlo is installed under the rafters up to the knee wall and sealed at the top with foam sealant. After the installation, inside air can’t get out of the house through the knee wall space and outside air can’t get in. Now with the knee wall properly insulated there should be significantly warmer upstairs in the winter and cooler in the summer, as well as less drafts throughout the home.
