Integrity from Marvin Windows

Integrity windows and doors are top of the line fiberglass products that offer the look of real wood with all the performance features of fiberglass. Low-maintenance and modern, Infinity windows are made of Ultrex®, a pultruded fiberglass patented by Marvin. With Ultrex and their proprietary pultrusion process, these windows are able to withstand almost any climate and endure. Proven tough, Ultrex is 8X stronger than vinyl and 3X stronger than vinyl/wood composites.

Infinity windows even incorporate the details of traditional wood, but you’ll never have to worry about maintenance associated with wood windows. They are easy to operate and clean as well. Plus, you can add a factory finish stain that can complement your existing woodwork.

The combination of Ultrex fiberglass and performance glass options on Infinity products exceed ENERGYSTAR® requirements. The result is a stunning, energy efficient window or door that keeps homes comfortable in all seasons.
