Insulating and Sealing a Leaky Attic House Fan in Wall, NJ

A homeowner in Wall Township, NJ had an uninsulated and leaky whole-house fan in their attic. Uninsulated and leaky fans allow conditioned air to escape into the attic or unconditioned spaces, leading to comfort issues, increased energy waste and higher energy bills. To address this issue, we installed our David Lewis Whole House Fan Cover on top of the fan. By pumpkin cutting the top and installing hinges, we created a functional door with a string for easy opening. This allows the homeowner to control airflow, opening the fan hatch to let air in when needed. When closed, the fan door seals the cover, providing insulation and preventing leaks. Now, this homeowner enjoys a properly insulated and sealed house fan, reducing attic leaks, improving home comfort, and saving energy.
