Many of you have an open window in your house and don't even know it, the shutters on your whole house attic fan. The louvers on the attic fan are not airtight or insulated. Heated room air escapes through them in the winter and heat radiates through them in the summer. The SHUTTERCOVER TRIM to FIT helps eliminate air infiltration. It attaches to attic fan shutters without going into the attic.

Louvers location: If your air conditioning system’s return air vent is near the attic fan, hot air is drawn from the attic instead of recirculating air from your home. This makes your furnace and air conditioner work harder, wasting energy. If your thermostat is near the attic fan, heat radiating from your attic tells the thermostat the house is hotter than it is really is, making your house colder than you want it and increasing your utility bills. If the louvers open when you close a door or when the wind blows, they don’t reseal properly.

Tests: The cover was independently tested by the Ozarks Area Community Action Corporation in Springfield, Missouri in May 2001. During a 20-mph wind test, in a moderate size home with the fan louvers in fair condition, a significant amount of air infiltrated the home through its attic fan opening. With the SHUTTERCOVER TRIM to FIT in place, air infiltration through the louvers and overall house air infiltration was reduced. The Low-E Class A White ™ radiant barrier insulation incorporated in the cover reduced heat loss, making the cover cost effective.

Installation: Three easy steps. Attach hook and loop, place cover on adhesive strips, remove cover and Trim to Fit
