Integrity Window and Doors' Wood-Ultrex line from Marvin Windows and Doors was named as Most Efficient in the fiberglass/composite window category by the Environmental Protection Agency for 2013. As part of the EPA’s Energy Star program, Most Efficient products are rigorously tested and achieve an independent certification above and beyond regular Energy Star certification. 

Integrity achieved the Most Efficient certification in Northern and North-central climate zones with its tripane Wood-Ultrex Series windows. Made with wood on the interior and Ultrex pultruded fiberglass on the exterior, Integrity windows are energy efficient, tough and durable. Integrity’s Ultrex material offers a mix of performance characteristics that can outperform roll-form aluminum, vinyl, and vinyl/wood composites, according to a Marvin Windows and Doors press release.

Integrity does not use any other filler gas besides argon, making it a cost-effective energy solution. Integrity’s argon-filled tripane glass has U-factors of .18 to .20, keeping heat inside the home to help lower heating bills. Available tripane window products from the Wood-Ultrex line include casement, awning, casement picture and casement direct glaze.
