Hot to mount a attic fan.

Mount the attic fan onto the plywood so it s centered over the hole. Place the fan mounting bracket on the plywood center the fan over the opening and screw the bracket to the plywood. We backed our screws with washers to keep the heads from pulling through. To save time use an existing roof or gable vent to install your new attic fan.

This way you don t have to cut a brand new hole but simply make the hole for the vent larger so it can accommodate the fan. This will help to avoid premature damage to the shingles or mold building up in moist hot. Trying to solve the heat gain problem in your attic by using a fan is like lying out at the beach with a fan blowing over you and thinking you re not going to get a sunburn. An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents.

Good insulation reduces fan effectiveness. The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. However the utility of attic ventilation fans is actually quite a controversial topic. Much of that heat then conducts downward and finds its way into the house.

Drill the screws that came with the fan through the screw holes on the fan s mounting bracket and into the plywood. The whole house fan is installed inside the attic between the living space and ceiling. You also want a fan that s appropriate for the square footage of your attic space by checking the manufacturer s specifications. On one hand the national renewable energy laboratory said attic ventilation reduces attic temperature 10 to 25 degrees and slows the transfer of heat into the living space.
