What you are feeling here is "hot air escaping"--its _NOT _"cold air
getting
in".......

Try thinking outside of your own little box just for once, my
friend....perhaps even do a cursory study of thermodynamics if it's
something that interests you.....

Actually Mr. Precision, both are happening. In the case of a large air
gap,
the outside wind will easily infiltrate. This will, of course, force air
to
leave by another port.

You can have heat loss through radiation and have no air exchange. You
cannot have air infiltration and now have air escaping in equal volume.



Otherwise, pressure keeps building till finally the garage explodes....so
better fix that other port while he's at it then....

But I wasn't fishin for Ed's--catch and release is all.
