Marvin still makes their windows and doors with techniques that have been refined and perfected over decades to meet the project’s exact specifications. The high quality and long-term value of Marvin products are a direct result of their craftsmanship, innovation and ability to create windows and doors to match almost any design and specification.

Marvin Signature Collection (previously known as Marvin Ultimate Collection)
Redefining the Standard. Made for those who care about every detail. The Marvin Signature Ultimate product line offers beautiful design, craftsman-quality construction and a vast selection of shapes, sizes and options. With extensive customization opportunities and versatility across architectural styles, Signature Ultimate windows and doors can be used in a wide range of projects – including traditional, contemporary, transitional, historic, craftsman or whatever style fits your project.
Unmatched Craftsmanship
Signature Ultimate windows and doors are available in a range of wood species and a variety of stains and paint options. Marvin sands, conditions, stains and oven-cures each individual piece of wood, providing a rich interior finish.
Design Possibilities
The beauty of Signature Ultimate is found in every thoughtful detail that, when combined, can completely transform how a room feels. It’s extensive selection of shapes, styles, sizes and options means more flexibility to meet any design challenge. And if you can’t find what you’re looking for, Marvin can help you make nearly anything you can imagine.
Extraordinary Innovations
Innovation is found in simple smart breakthroughs like Marvin’s Lift Lock hardware, which allows for easy access to open and lock a window. It’s in Marvin’s Lock Status Sensor: a home automation solution that gives homeowners peace-of-mind because it indicates if a window or door is closed and locked, or if it’s unlocked.

Marvin Elevate Collection (previously known as Integrity Wood-Ultrex®)
An ideal blend of design and strength, patented fiberglass exteriors stand up to all elements, outperforming and outlasting vinyl, while warm wood interiors add timeless beauty.Proven Strength
Marvin’s proprietary fiberglass is 8x stronger than vinyl and 3x stronger than vinyl/wood composites. It resists fading, chalking, peeling and cracking.
Stylish Design
Warm wood interiors and on-trend styles; every feature and options has been carefully considered so the windows can either make a statement or blend into the existing décor.
Powerful durability
Marvin’s pultruded fiberglass remains stable in extreme temperatures and expands at nearly the same rate as glass, so Elevate windows stay square and strong even in harsh conditions.
AAMA Verified Fiberglass Finish Ultrex is the first fiberglass finish to be verified to any of AAMA’s 624-10 voluntary finish specifications for fiber reinforced thermoset profiles (fiberglass). The Ultrex patented acrylic cap finish is verified AAMA 623-10 and 624-10, and has passed the AAMA 625-10 lab-based performance test protocols; 625-10 outdoor weathering test protocols are in process. With the industry’s best fiberglass finish, Ultrex resists fading, chalking, scratching, and cracking to keep your project looking good for years to come.
