Integrity Windows and Doors

The Marvin brand of Integrity windows and doors are renowned for their durability, energy efficiency, superior finish and overall value.


Every Integrity product features the company’s patented Utlrex pultruded fiberglass. The material is eight times stronger than vinyl, and can outlast roll-form aluminum as well as other fiberglass composites. Integrity’s slogan, “Built to Perform,” speaks to their windows’ ability to remain stable in any weather condition.  On average, the Ultrex life expectancy is 38% longer than vinyl.

Energy Efficiency

In addition to being tough, Integrity windows and doors are energy efficient. Integrity products meet national Energy Star guidelines. In addition to reducing your environmental impact, you’ll also benefit from savings on your heating and cooling bills.

Superior Finish

Integrity windows and doors with Ultrex fiberglass feature a superior finish that lasts longer than conventional doors. Ultrex is the only fiberglass available today that has been verified to AAMA’s 624-10 finish specifications for reinforced fiberglass. Ultrex resists fading, cracking, peeling and chalking, and provides unparalleled protection from the elements. With Ultrex, your home will look great for years to come.

Overall Value

The focus of the Integrity line was to create windows and doors that would add value to your home’s integrity and style in addition to saving you money. The long-lasting Ultrex fiberglass can withstand rain, snow, wind and sleet without peeling or cracking. The glass is also a superior insulator and can help lessen heating and cooling bills by keeping your home at a consistent temperature. For a great value, shop Integrity windows and doors and Salem.
