Strike the perfect balance of beauty and strength

The Marvin Elevate™ collection is an ideal blend of remarkable design and superior strength, bringing balance to your style and performance needs. Proprietary 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 stays strong in even the toughest conditions.
