Hot To Mount A Attic Fan

However the utility of attic ventilation fans is actually quite a controversial topic.

Hot to mount a attic fan.

The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. Good insulation reduces fan effectiveness. The whole house fan is installed inside the attic between the living space and ceiling. 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.

We backed our screws with washers to keep the heads from pulling through. Drill the screws that came with the fan through the screw holes on the fan s mounting bracket and into the plywood. 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. To save time use an existing roof or gable vent to install your new attic fan.

Lay the plywood on a flat surface and line the fan up over the hole you cut out. Whole house fans work on the principle of removing the hot and humid air out of the house. It helps to cool your home temperatures and the attic by approximately 30 degrees. This will help to avoid premature damage to the shingles or mold building up in moist hot.

You also want a fan that s appropriate for the square footage of your attic space by checking the manufacturer s specifications. 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. 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. Mount the attic fan onto the plywood so it s centered over the hole.
