Hot Garage Ventilation

By Tim Carter
©1993-2008 Tim Carter
Summary: Does your garage heat up like an oven? Once the heat builds up in the objects in the garage, they can radiate heat for hours after the direct sun is gone. Insulation and ventilation fans will help reduce the temperature inside your hot garage.

Dear Tim,
I have a detached 2 car garage (garage doors facing south) with a fenced in brick layered back yard that gets sun (end unit townhouse) from the east and south. My back yard gets extremely hot and I'm sure a lot of the heat is keeping me from being able to cool off my garage. What type of ventilation fans might be best for my situation? The garage area is 20x20x9ft and the attic is about 1400 cubic feet. This was the only article I found about garage ventilation and their scenario seems much different than mine.

Thanks for any help.

Regards,
Ted

Dear Tim,

Would a roof turbine vent be effective for cooling my garage? The garage is open up to the roof, so there's no insulation in what would normally be attic space. I have a highly insulated garage door newly installed that has turned the garage into an oven, and am looking for ventilation options. Is a roof turbine sufficient, or would sidewall ventilation fans be better?

Thanks,

Matt

I live in St. Louis and many of the neighbors on our street keep their garage doors open partially in the summer. Is this a benefit of some sort? Nobody really has a good reason for doing it and it doesn't look good.
