Extraordinary Innovations
Marvin Elevate Collection (formerly Integrity Wood-Ultrex®)
An ideal blend of design and strength, patented fiberglass exteriors stand up to all elements, outperforming and outlasting vinyl, while warm wood interiors add timeless beauty.
Proven Strength
Marvin’s proprietary fiberglass is 8x stronger than vinyl and 3x stronger than vinyl/wood composites. It resists fading, chalking, peeling and cracking.
Stylish Design
Warm wood interiors and on-trend styles; every feature and options has been carefully considered so the windows can either make a statement or blend into the existing décor.
Powerful durability
Marvin’s pultruded fiberglass remains stable in extreme temperatures and expands at nearly the same rate as glass, so Elevate windows stay square and strong even in harsh conditions.
