[Shop-talk] Garage ventilation?

[Gerald Brazil]

One of the best things I ever did in the home improvement mode was to
install a "whole house attic fan". It took quite a bit of work, because you
have to have a large louvered (spring loaded) exit in a gable to exhaust the
large volume of air it can move. On high, ours will nearly suck the
wallpaper off of the walls.

If you come home to a hot house, just open a window in each room and turn
the thing on high (don't leave any papers around) and run it for 5 or 10
minutes. Turn it off, shut the windows and turn the AC on....it gets rid of
the hot air in both house and attic.

With something like this in your shop you could even do a little touch up
painting and get rid of the fumes....however, don't do any big painting
projects without installing some sort of filter to protect the motor because
this type of motor isn't intended for that.

I don't see why not ... but why not put the exhaust fan between the attic
and outdoors ?
My garage 'attic' is open to the garage (I store car parts up there), so
that's what I do.  For the moment, I have the exhaust fan's thermostat set
fairly low, but powered from the light switch for the garage so it only runs
when I'm out there (and the weather is warm).  Ideally (someday), I'd like
to add a second thermostat that would run it any time the attic got over
100F or so, to reduce heat gain to the house through the (mostly
uninsulated) wall between them.

Insulating the west wall (which in my case is mostly the door) made a big
difference too.
