Extruded Aluminum Cladding

Marvin WindowsAll aluminum cladding is not created equal. Marvin’s extremely durable extruded aluminum substrate is significantly stronger than roll-form aluminum. With such a high-performing finish, Marvin offers a 20-year warranty* against loss of adhesion, chalking or fading.

Color Options

Deep, rich and lasting. These are just a few words that describe the difference of Marvin color. From subtle earth tones to bold, attention-grabbing hues, Marvin’s cladding stands out as much for its beauty as it does for its legendary durability.

Wood Options

Marvin makes it easy to complement any project or design with an array of high-quality standard wood options, including Pine, Cherry, Douglas Fir, Mahogany, Vertical Grain Douglas Fir and White Oak.

Marvin Windows

Marvin Elevate Collection (Formerly Integrity Wood-Ultrex)

Marvin WindowsThe Marvin Elevate Collection is an ideal blend of design and strength. Patented fiberglass exteriors stand up to all elements, outperforming and outlasting vinyl, roll-form aluminum and other fiberglass composites. Warm wood interiors add timeless beauty while resilient, long-lasting fiberglass exteriors stay strong even in nature’s toughest conditions.

Marvin Essential Collection (Formerly Integrity All-Ultrex)

Marvin WindowsThe Marvin Essential Collection offers clean lines and versatile style. Strong, durable fiberglass interiors and exteriors are both visually appealing and virtually maintenance-free. Marvin’s Essential Collection is great for homeowners wanting narrow frames and more glass, perfect for a contemporary look.

The Strength of Ultrex Fiberglass

Marvin WindowsThe strongest window wins. These are the facts: Ultrex is eight times stronger than vinyl and three times stronger than wood/vinyl composites. Ultrex is as strong as steel. So, when a house settles in and time marches on, Elevate and Essential windows stay true and resist sagging for years to come.
