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.
Marvin is the leader in fiberglass, which outlasts vinyl windows by 38%1. Our pultruded fiberglass remains stable in extreme temperatures and expands at nearly the same rate as glass, so Essential windows stay strong and true, even in harsh conditions.
