I was about to install a solar fan, I nixed that idea.

the attic door should not have a grille or be left open, surprised a retired fireman hasn't jumped in on that issue, It would feed O2 into the flames.

Been thinking about taking an exhaust fan from the garage ceiling and ducting it thu the roof.

Much like your stove / microwave is done or bath fan.

they R under $100, safe and you would only be taking the air out of the garage space.

Tommy, insulating the ceiling and door must have a positive effect but how many years to recoup that investment?

I like this idea.
