Whole House Fans: Shutter Seal

Reviewed by:
The Old House Web

When the weather outside's not delightful, the shutters on your whole house fan may be letting in a lot of unwanted air. The Whole House Fan Shutter Seal installs over the fan louvers from the house side, so no attic access is required.

Attached with velcro, the foam-filled cover is rated at R-8 and will fit fans up to 48" square. Larger sizes can be special ordered.

  • Whole House Fan Shutter Seal fits up to 48" square fans and costs $30 (July 2006).
