Integrity Named Best Quality Fiberglass Window Brand”


Integrity Windows Named Best Quality Fiberglass Window Brand by BUILDER Magazine

FARGO, N.D.—Integrity® from Marvin Windows and Doors has been named the “Best Quality Fiberglass Window Brand” in a recent Brand Use Studyconducted by BUILDER Magazine. 

The study, sponsored by publisher Hanley Wood and conducted by an independent third-party research company, surveyed more than 10,000 builders, developers and general contractors on their awareness and use of various brands in 69 different categories. Respondents were asked their overall familiarly with brand, usage and opinion of the manufacturer’s quality.

“This third-party validation backs up what we’ve known about the Integrity brand for years—that we lead the fiberglass category based on our product innovation and quality,” said Becky Felling, Integrity Director of Marketing. “Our Ultrex® fiberglass windows are a superior product that trade professionals and homeowners have really responded to. It’s tough, virtually maintenance-free and it looks great in any home, making it an ideal fit for a wide variety of projects.”

Integrity’s fiberglass windows are made with Ultrex—a state-of-the-art pultruded fiberglass that is eight times stronger than vinyl, three times stronger than wood/vinyl composites and as strong as steel. Integrity offers an All Ultrex fiberglass line of products, as well as a Wood-Ultrex line that combines an authentic wood interior with a virtually indestructible fiberglass exterior. Both lines are available with numerous design and glazing options for both new construction and the remodel and replace market, and are available in six exterior finish colors (including darker colors such as Ebony, which most vinyl manufacturers cannot offer due to durability and fading concerns).

The toughness of Integrity’s Ultrex is legendary, making it quite possibly the perfect building material. It beautifully resists rotting, warping, fading and chipping. Additionally, Integrity’s Ultrex is currently the first and only finish to have achieved 624-10 verification from the American Architectural Manufacturers Association (AAMA), and to have completed lab requirements for 625-10. These certifications mean that the industry’s best fiberglass finish has undergone rigorous testing and is proven to resist fading, chalking, scratching and cracking to keep your project looking good for years to come.

“We’ve always known how durable our finish is, but it’s great for our customers to have independent corroboration,” Felling said. “It truly shows that when you buy an Integrity window or door, you’re getting the whole package: beauty, durability, performance, outstanding service and support, backed by Integrity’s unmatched 10-day delivery to the distributor.”

Our Work
What Our Customers Are Saying
"We chose Lakeshore Windows and Doors after sourcing out many competitors to make sure we got the right company for the job."

We are very pleased with the work Lakeshore did on replacement windows for our home! They also enlarged some of our windows and the cutting of the brick was precise and professionally completed.

Lakeshore Windows worked diligently, efficiently and most of all neatly respecting our home and the standards of our family lifestyle.

It was our pleasure to do business with Dave Huiting of Lakeshore Windows.
