Fiberglass Windows for San Juan Capistrano Homes
Fiberglass expands and contracts at nearly the same rate as glass, so seals stay tight through hot days and cool nights. The strength of the material allows narrower frames and larger glass areas, and factory finishes — including dark colors — resist fading in strong sun.
The marine layer keeps San Juan Capistrano mild most of the year, but afternoon sun on west- and south-facing walls still drives heat gain, so Low-E glass with a low solar heat gain rating keeps those rooms comfortable.
