There are often gaps between your shutter and the whole house fan. In the winter, heated air can escape your home through these gaps, while the cold outside air flows right in. Then in the summer, hot air will seep into your house, costing you more to keep your home at a comfortable temperature. Allowing constant air transfer can also contribute to ice dams and attic mold, costing you even more money in repairs.
The Battic Door Whole House Fan Shutter Seal installs in minutes to cover and seal the shutter, blocking the transfer of air and moisture. It also prevents the entry of noise, attic dust, pollutants, insects, and rodents into the living area and attic. Attached to the fan shutter with Velcro, this seal can easily be taken off at any time.
The seal's insulation is made of a durable, non-toxic, space-age foam, only 3/16" thick, yet has an R-value of R-8. The foam air seals and insulates the attic fan, stopping heating and cooling loss and air leaks. The insulation is a Class A/Class 1 fire rated foam with superior thermal performance. No fiberglass - no itching.
These seals are also available in small
sizes, each sold separately. Each seal can also be cut for an exact fit for your shutter size.
