I knew this guy that put one of those whole house fan in the wall and just opened the windows and garage door just a little an it was like air condition in there.
Did you vent the roof ? Heat trapped at the top of the roof will make the whole garage hot. A power vent attic fan may be what you need.
2x4 construction or 2x6? That matters because of the amount of insulation you can put in the walls(more the better) Also is the ceiling insulated(double the walls). Garage door for the cars insulated and the seal around the garage door tight?? Also the color outside the garage. Dark colors? Roof dark color? No different than wearing dark clothing on a summer day. (only if you want to death by heat) Windows - Singlepane? doublepane? triplepane? Look at heat as you would look at cold freezing temperatures. Same protection is required to keep temperature moderate in garage instead of ';extreme';.


which side is garage on. South side(meaning in the sun all day?) It is gonna be a cooker. Plant trees that can keep the garage in the shade will help. Build a seperate second wall with a walkway inbetween will shade the garage walls. Move your house to Paulin country will help.
