Why have an attic.
Powered attic ventilator fans designed to cool your attic by drawing the hot and humid air out of the attic and bring in a flow of chilly air from outside.
Interior ceilings are generally flat and roofs are pitched to shed rain and snow so the dead space in between becomes the attic.
You place the fans on the gable walls of your attic.
Once inside the air heats up and rises higher ultimately exiting through venting at the roof s gables through ridge vents cut into the roof s apex or other vent holes in the roof.
Most homes already have some passive attic venting built in.
Cool air enters the attic through soffit vents in the eaves.
It s not all wasted space though since it can be used for access storage or simply as an insulation thermal buffer.
