Marvin Windows and Doors now offers a wide range of wood windows made in the USA that will meet both the strict European and U.S. standards for Passive Building certification. And for homeowners and building professionals looking for highly efficient windows, Marvin offers more products that have earned ENERGY STAR’s “Most Efficient” designation than any other wood-window manufacturer.

No longer will builders and owners have to wait for more than two months for passive windows to ship from Europe. Marvin’s R&D and manufacturing teams have achieved what had been considered impossible by many in the industry: delivering American-made windows that meet Passive Building standards while maintaining the highest levels of beauty, style and customization. Passive Building certification from both U.S. and European bodies is pending.
