FARGO, ND--(Marketwire - Mar 20, 2013) - Integrity® from Marvin Windows and Doors continues to outperform any window in the fiberglass/composite category with products from their Wood-Ultrex line named as Most Efficient by the EPA. As part of the EPA's ENERGY STAR program, Most Efficient products have gone through rigorous testing and independent certification above and beyond regular ENERGY STAR certification. Homeowners buying Most Efficient products such as Integrity's certified offerings will be able to know that their purchases are among the most energy efficient on the market.
Integrity Windows and Doors achieved the Most Efficient certification in several climate zones with its tripane Wood-Ultrex Series windows. Made with wood on the interior and Ultrex® pultruded fiberglass on the exterior, these windows are energy efficient, tough and durable. Integrity's pioneering Ultrex material offers a unique mix of performance characteristics that vastly outperforms roll-form aluminum, vinyl, and vinyl/wood composites.
Unlike many other tripane windows on the market, Integrity can achieve its Most Efficient certification without the use of any other filler gas besides argon -- making it a cost-effective energy solution. Three panes of glass and argon gas combine to create the ultimate in performance, beauty and strength. Integrity's argon-filled tripane glass has U-factors of .18 to .20, which means that it has superior insulating properties, keeping heat inside the home to help lower heating bills.
Integrity is certified as Most Efficient in the Northern and North-Central Climate Zones. Available tripane window products from the Wood-Ultrex line include the Casement, Awning, Casement Picture and Casement Direct Glaze. These windows are available with all current product options such as grilles, hardware and exterior colors. As part of the Marvin family of companies, Integrity shares Most Efficient certification with its sister brand Marvin Windows and Doors.
"Today's homeowners want windows that perform efficiently to make their homes as comfortable as possible," said Becky Felling, Director of Marketing for Integrity Windows and Doors. "We are delighted that so many of Integrity's products are recognized by ENERGY STAR as Most Efficient. Our company has been committed to performance for decades. We pioneered the fiberglass window category and continue to lead with a dedication to making our windows as energy efficient as possible."
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy.
