Questions homeowners ask

Why is fiberglass considered superior to vinyl?

Fiberglass expands and contracts at virtually the exact same rate as glass. This eliminates stress on insulated glass sealants, resulting in the lowest seal-failure rate in the window industry.

Can fiberglass windows be painted in the future?

Yes! Unlike vinyl, pultruded fiberglass accepts exterior paint finishes if you ever want to change your home exterior color scheme.
