Integrity Windows

Integrity Windows: The perfect way to enhance your view, both indoors and out. 

Durability and style - that's Integrity from Marvin, a company with a rich history of craftsmanship, knowledge and dedication dating back to 1912.  Featuring the strength and beauty of Ultrex® pultruded fiberglass construction, Integrity fiberglass windows come in full line of popular styles, like casement, awning and double hung.  All Ultrex windows look incredible and their 100% fiberglass construction outperforms and outlasts vinyl, aluminum and composite materials. Wood-Ultrex windows combine an authentic wood interior with a virtually indestructible fiberglass exterior. Factor in our IMPACT Products for coastal applications and there is no doubt Integrity windows are Built to Perform®.

Strong, stable, durable and virtually indestructible, Ultrex® is possibly the perfect building material, creating windows that leave other materials in the dust.  No other material can match it - it's eight times stronger than vinyl and three times stronger than wood/vinyl composites. While other windows might bow or chalk over time, Integrity windows undergo a patented, high-performance coating process, resulting in windows that perform under great stress without showing age or wear.

When it comes to energy efficiency, Integrity is an industry leader in mastering heat, sun exposure and air flow. Our unique combination of customized glass coatings, gas insulating, energy panels and air-tight framing work together to deliver energy savings on heating and cooling costs.  All Integrity products meet or exceed federal Energy Star guidelines.
