Marvin® Certified by Passive House Institute U.S.

With efficiency and beauty, trusted name leads industry in U.S.-made passive design solutions.

Marvin Windows and Doors is pleased to announce that it has received certification from the Passive House Institute U.S. (PHIUS) for its Ultimate Casement window.

Now architects, builders and homeowners seeking a passive solution can turn to a trusted name for an American-made product. Marvin’s innovative passive window option combines the beauty of warm wood interiors with exceptional performance, all backed by a century-old heritage of quality and service.

Windows are a key consideration in passive building design. Because our products are made in the USA, Marvin Windows and Doors can offer builders a shorter lead time than international manufacturers. And our extensive independent dealer network means we can support the project from the time it’s drawn up until after installation. This is another great example of Marvin working one-on-one with its customers to deliver the perfect windows for each project along with high-tech building solutions.

Marvin’s Ultimate Casement offers a 10-year warranty on parts and workmanship and 20 years on glass. Marvin also achieves lead times of less than 8 weeks — unlike European providers that often specify much longer lead times.

Marvin’s Clad Ultimate Casement meets PHIUS certification in two zones: Zone 3 and Marine South, per the International Energy Conservation Code (IECC) map. The Ultimate Casement is available with tripane glass in an 1 3/8” profile or quad glazing with Heat Mirror®* technology in a 1” profile.

With our long history of custom manufacturing and our skilled, experienced work force, we’re able to craft windows that will meet the highest standards of energy efficiency while allowing design freedom.

The Ultimate Casement comes in a virtually endless range of styles and sizes. With six wood species options and nine factory-applied interior stain and paint finishes, customers can create a window to fit any home. The Ultimate Casement offers 19 standard exterior clad colors with an industry leading AAMA 2605 finish as a standard and an extensive range of custom colors.

Marvin Windows and Doors also offers a wide range of additional windows made in the USA that will meet both the strict European and U.S. standards for passive building. Certifications on those products are pending.
