A gable mount fan can do a lot to reduce attic temps where sun exposure
is a big problem. That reduces the heat transmission into the interior.

While static venting is great, you probably don't have the luxury
right now to experiment with it.

Personally, I would mount it to exhaust the hot air.
Be sure that all inlets are screened as well as the gable outlet
to keep bugs out.

PSC fan is "permanent split capacitor". Refers to the
type of motor. They run more efficiently, esp when run at
reduced speeds.

You'll need to pick the time you work up in the attic
carefully; if hot up there you put yourself at risk working.

Hi Joe and Jim,

Thanks very much for the prompt reply. In the summer, the sun comes up
at 6 AM and sets at 8PM; that's 14 hours of no-shade exposure to the
concrete tile on the roof.

Yes! We are attempting to keep the attic as cool as we can, Joe.

Yes Jim, I think that we will just have to wait until November to
complete this project. Our local DYI store is offering some of these
attic fans now and from what you have said, the "PSC", 14" fan sounds
like the one we'll purchase.

Again, thanks for all of your help with this, guys!

Norman
