[Shop-talk] Garage ventilation?

[Doug Braun]

We have a nice big whole-house fan for the actual
house.  I love it. It's running right now.  One thing
I would like to do is figure out a good way to seal it
off during the winter, to reduce heat loss through the
closed metal lovers.  Maybe I make a box-like thing
out of styrofoam panels that I can place over the fan.

But the garage situation is different.  Building codes
mandate a continuous barrier of fire-resistant drywall
between the garage and living spaces, and if I
penetrated the garage ceiling, I would probably have
to add some more drywall in the garage attic where
part of it abuts the master bedroom.
