How do I measure plexiglass to replace a garage window? I understand
plexiglass contracts & expands more than glass. Any advice on this
project appreciated.


When I replaced mine, the glass dealer suggested making the piece 1/16"
smaller than the opening on each side. I haven't had any problems with the
installation, and the temps here range from mid 90s down to zero.
