Marvin Essential™ Windows

Marvin Essential™ Windows

Previously known as Integrity All Ultrex®

The Marvin® Essential collection is a streamlined product line, with windows that suit a wide range of needs.

They’re strong. With a fiberglass frame that’s eight times stronger than vinyl and three times stronger than vinyl/wood composites, they’re built to last.

They’re durable. Marvin’s innovative fiberglass is stable in the face of extreme temperatures and it expands at the same rate as glass for superior performance.

They’re appealing. Not only do Marvin Essential windows look great, with narrow profiles and clean lines, but they also bring simplicity to the ordering process with a turnkey set of options to choose from.

Did we mention they’re virtually maintenance-free? That’s right, the strength and durability of fiberglass means more time to enjoy them and go about your daily business.
