Marvin Elevate
Ultrex Fiberglass
The facts speak for themselves. Our proprietary fiberglass is eight times stronger than vinyl and three times stronger than vinyl/wood composites. It resists fading, chalking, peeling, and cracking.
Fiberglass has an amazing strength-to-weight ratio, which is one of the reasons it’s the material of choice for boats, bridges, guardrails, ladders, and hard hats. It’s also highly durable, doesn’t leak, corrode, or rot, and unlike vinyl and non-fiberglass vinyl/wood composites, Ultrex is extremely stable.
