Strong, durable fiberglass exteriors and interiors are both striking and virtually maintenance-free. Simplified options make the order process straightforward, while clean lines and versatile styles make it easy to meet project demands.


Proven Strength

Marvin’s proprietary fiberglass is eight-times stronger than vinyl and three-times stronger than vinyl/wood composites. It resists fading, chalking, peeling, and cracking.


Powerful Durability

Marvin is the leader in fiberglass, which outlasts vinyl windows by 38%.[1] Their protruded 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.
