About Fiberglass Windows
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.
Best for
Homes with lots of sun exposure, dark exterior colors, and homeowners who want a longer-lasting premium frame.
