Essential: Straightforward and Tough
-
Proven strengthThe 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.
-
Powerful durabilityMarvin is the leader in fiberglass, which outlasts vinyl windows by 38%. 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.
-
Streamlined detailsWith narrow profiles, clean lines and simpler features and options, Essential makes it easier to choose and order.
