Top Benefits of Marvin Windows and Doors

Exceptional Strength and Durability

Marvin's proprietary fiberglass is 8x stronger than vinyl and 3x stronger than vinyl/wood composites, ensuring long-lasting performance and resistance to damage such as fading, chalking, peeling, and cracking.

Superior Performance in Extreme Conditions

Marvin windows remain stable in extreme temperatures, expanding at nearly the same rate as glass, making them ideal for harsh conditions with minimal maintenance required.

High-Quality, Customizable Design

Marvin offers narrow profiles and frames for a contemporary look, with both standard and special sizing options available. Their windows and doors feature pultruded fiberglass inside and out, applicable in new construction, replacement, remodel, and light commercial projects.

Client Testimonials

“As an active New Construction & Residential Remodel Project Manger, I am constantly ordering new doors & windows for all kinds of projects. No matter what size of project it is, (2 windows or 40), I always receive professional customer service and attention to detail from Dave and his team at Designer Window Supply.”
Kurtis Kaelin
“When I went to the showroom, I met with Krystal. They not only just supply the windows/doors but also make sure the installation material for their products is used so the product is installed properly... Their product, installation, and customer care is unparalleled. I would highly recommend them for any small or large scale project.”
