When shopping for windows, it’s important to focus on the four main categories: materials, efficiency, design, and value.

At GIANT Siding and Windows our preferred window brand, Marvin offers homeowners a durable window, with superior finishes, with industry-leading energy efficiency available in a wide array of window treatments.

The Marvin company approaches material selection differently then many other window manufacturers and holds themselves to a higher-strander. We get this, just like Marvin we are a family-owned company.

Marvin’s window and door materials—wood, extruded aluminum, High-Density Fiberglass and Ultrex® fiberglass each offer unique benefits. If you’re not sure what’s best for your project or your climate, a Marvin window and door dealer can help recommend the material with the right attributes.

Ultrex fiberglass is eight times stronger than vinyl and three times stronger than vinyl/wood composites. It resists fading, chalking, peeling and cracking, giving you unparalleled strength and durability.
