Marvin Integrity Windows

The Integrity Series are premium quality windows designed to withstand the worst possible weather with the least possible maintenance. These hybrid windows use fiberglass exterior frames married to wooden interiors.Fiberglass is used on the exterior because it is highly resistent to decay, has about the same expansion rate as glass, does not allow moisture penetration and requires minimal maintenance.

To maximize energy efficiency, Integrity series windows come standard with Low E II insulating glass. Argon gas is added to the air space to further improve energy efficiency. This eye toward energy conservation has resulted in windows exceeding the standards required to qualify them for the U.S. Department of Energy and U.S. Environmental Protection Agency Energy Star program.

Because the exterior frames are finished with a special coating, they require no additional finish. Available in white and pebble gray, the factory finish won’t peel, crack, or chip. Unlike vinyl and aluminum, these exteriors readily accept paint, allowing you to coordinate the window color to your home. All standard and most custom Integrity Series windows can be optionally fitted with either internal or external grids. The external grids are made of wood and are held in place with spring loaded pins. This allows for easy removal for cleaning. While the external grids can be finished to whatever color you desire, the internal grids are available in white only.
