I have a pretty standard steel double garage door. My garage gets up
to about 145 degrees during the summer mostly because my house faces
the sun pretty much all day. Is there any value to me adding
insulation to the garage door panels? It seems to me that some kind
of styrofoam insulation would fit perfectly in the panels. I've seen
the kind with the metallic coating on it before. Would this help or
am I wasting my time?

Thanks, Chris

I had a similar problem mhere in Canada - very hot in the summer and
very cold in the winter. Compoundng the fact, my family room directly
adjoins the garage so it was influenced as well.

I insulated and it made a huge difference. FWIW, I also addressed the
air infiltration problem around the doors which made a larger impact
in the winter.

Also, I originally used a mastic type of tube compound to tag the
insultaion on, but eventually it popped off because of the temperature
shifts. I ended using straps and also the aluminum heating duct tape
which worked well. I simply used the syrofoam sheets cut and notched
on my tablesaw to fit in the door panels.
