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,” said Christine Marvin, director of marketing for Marvin Windows and Doors. “Because our products are made in the USA, Marvin 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.”
