Designed for homeowners who value strength, simplicity, and low maintenance, the Marvin Essential™ Collection offers clean, contemporary lines with the unmatched durability of fiberglass—inside and out.

Strong, durable fiberglass exteriors and interiors are both striking and virtually maintenance-free.

With streamlined designs and proven performance, Essential windows and doors are a smart, stylish choice for any project.

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 and clean lines, the Essential Collection delivers modern appeal and maximized views. Available in a range of popular styles and configurations, these windows and doors suit a variety of home designs—from transitional to contemporary.
