Hot to mount a attic fan.

It helps to cool your home temperatures and the attic by approximately 30 degrees. 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. The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. To save time use an existing roof or gable vent to install your new attic fan.

Drill the screws that came with the fan through the screw holes on the fan s mounting bracket and into the plywood. Mount the attic fan onto the plywood so it s centered over the hole. 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. Much of that heat then conducts downward and finds its way into the house.

Good insulation reduces fan effectiveness. Place the fan mounting bracket on the plywood center the fan over the opening and screw the bracket to the plywood. Using a fan to blow hot air out of the attic doesn t address the radiant heat flow from the roof to the attic floor. Lay the plywood on a flat surface and line the fan up over the hole you cut out.

We backed our screws with washers to keep the heads from pulling through. Whole house fans work on the principle of removing the hot and humid air out of the house. 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.
