Knee Wall Insulation in Baltimore, MD
Knee walls are common in most homes, yet you may not know what they are. A knee wall is a short wall that is approximately two to three feet high. Knee walls are often found in attics, but are not necessarily in all attics. They are used to block in the unusable space where the rafters meet the top plates/attic floor. This creates more usable attic space.
Go into the attic or simply imagine yourself in the attic. If your attic is unfinished, it has a triangular shape. At the bottom points of the triangles, the rafters meet the top plates of the exterior walls. This is where a knee wall is installed.
The space behind the knee wall is often not insulated or air sealed, and the wall itself does not provide enough thermal barrier to protect the temperature of the attic interior.
Insulating knee walls can help protect the temperature of your attic and the interior temperature of your home.
Benefits of Knee Wall Insulation
Fully insulating your attic is one of the best ways to improve your home’s energy efficiency and cut down on energy bills. More than 70% of energy lost in your home is due to upward airflow, so ensuring your attic is fully insulated and air sealed will help prevent climate controlled air from escaping. That means your home will stay warmer in the winter and cooler in the summer without overworking your heating and air conditioning systems.
Insulating knee walls is a piece of the insulation process that can be overlooked and lead to unnecessary heat loss. Our experienced professionals at DeVere Insulation Home Performance will identify whether you have a knee wall and ensure it is thoroughly insulated to keep your home protected from the elements.
