We take great pride in installing replacement windows from Marvin®, an award-winning manufacturer with a long-established reputation for innovation and exquisite craftsmanship.

Why Our Fiberglass Windows Are a Cut Above the Rest

Fiberglass windows are a worthwhile investment for homeowners who want to replace their windows one time and feel confident that they’ve made a smart, low-maintenance choice. Fiberglass is the ideal window-frame material because it doesn’t expand and contract with temperature changes, and it doesn’t absorb moisture. This means it won’t swell and shrink as the years go by, which could put your all-important window seal at risk.

However, Marvin® replacement windows are even better suited to the climate in the Lenexa area because of their superior construction and use of the manufacturer’s proprietary Ultrex® fiberglass. This frame material is eight times stronger than vinyl and three times stronger than wood. Why is that significant? It allows Marvin to produce windows with remarkably slender frames that are strong enough to securely hold large expanses of energy-efficient glass, thus maximizing your view of the outdoors.

Marvin also understands the importance of providing plenty of customization options, so homeowners can enjoy long-lasting and energy-efficient fiberglass windows that suit their tastes to a T.
