CANTILEVERED FLOOR INSULATION

A cantilevered floor is anywhere on the exterior of your home where you see a “bump out”. It’s a floor that extends beyond the foundation or supporting wall below it. Cantilevers can be used to create bump-outs, bay windows, rooms over porches, or to make upper floors larger than lower floors. Unfortunately, cantilevers can be a common source of heat loss in a home because there is commonly air leakage through cantilevered floors due to gaps or insufficient insulation around the floor assembly, leading to unwanted airflow between the interior and exterior of the home. In order to alleviate the air leakage, installing dense packed insulation is a great solution to this problem.
