The Marvin Essential collection brings together design, quality, and performance in one streamlined offering.

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

The facts speak for themselves.

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%.

Marvin’s 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 Details

With narrow profiles, clean lines and simpler features and options, Essential makes it easier to choose and order.
