Fiberglass Windows by Integrity from Marvin installed by George J Keller & Sons

Integrity Replacement Windows in Northern New Jersey

Integrity Windows and Doors were born from The Marvin Companies’ century-long heritage of service, craftsmanship,and quality with a focus on all-out performance. Integrity windows and doors are built with Ultrex® pultruded fiberglass exteriors paired with either rich wood or Ultrex fiberglass interiors for a long-lasting, virtually maintenance-free window and door solution.

Here are some Integrity Replacement Window benefits for you:

Ultrex Tough, Ultrex Durability
Tough is what we test. Performance is what we prove. Through a variety of punishing tests in harsh conditions, Integrity windows made with Ultrex come out on top again and again. Ultrex expands at nearly the same rate as glass, resulting in windows that keep their seal and don’t leak. Watch this video and see just how tough Ultrex really is!

Ultrex Strength

The strongest window wins. These are the facts: Ultrex is eight times stronger than vinyl and three times stronger than wood/vinyl composites. That’s as tough as steel. So when a house settles and time marches on, Integrity windows stay true and resist sagging—proving that they’re truly built to last.

Energy Star Qualified Solutions
Integrity from Marvin Windows and Doors combines the low conductivity and superior performance attributes of Ultrex with a selection of energy-efficient glazing options to deliver ENERGY STAR qualified solutions.
