Changing the Market for Highly-Insulating Windows and Low-e Storm Windows

I'm sure you've heard about the DOE-led Windows Volume Purchase Program   a market transformation effort poised to overcome the barriers of cost and awareness that many new energy efficient technologies face. In fact, due to the limited awareness of highly-efficient window products, it had remained difficult for an individual window manufacturer to invest in the production capacity necessary to produce cost effective products...until now.

The program kicked off on May 27th, 2010 (an effort over two years in the making), after working with both window suppliers and buyers to ensure the program's effectiveness. Volume Purchase Team Members from DOE, Pacific Northwest National Laboratory (PNNL), Lawrence Berkeley National Laboratory (LBNL), the Alliance to Save Energy (ASE) and Energetics Incorporated educated end-users and bulk purchasers on the cost and energy savings these windows produce, while at the same time coordinating with suppliers to develop final window specifications for program participation and on marketing efforts. In the end, everyone benefits – manufacturers have a market for their products, and customers benefit from competitive prices and energy efficient products.

Today, qualified R-5 and low-e storm windows and R-5 patio doors are listed on the program's Web site. The DOE is committed to making this program a collaborative and transparent process with window manufacturers and looks to continue the early success of the program throughout the year and into a phase II effort. Visit DOE's Web site to learn more about the Windows Volume Purchase Program.

    I have been living on the North Slope in Alaska, specifically, Barrow, Alaska, for over 50 years, the northern most point on the North American Continent and have never been able to locate windows that meet our cold weather climate.
    We commence freeze up around Labor Day in September and thaw commences around the middle of May.  That is about 8-1/2 months of below freezing temperatures.  
    The North Slope is the ONLY Arctic Region in the United State of America.  Other states in the lower 48 do experience below freezing periods in the Winter months, such as Montana, Wyoming, North Dakota, Wisconsin, Minnesota, and possibly others states, but not for the duration of time that we do in Barrow, Alaska.
    I would like to know where the our nearest supplier of qualified R-5 and low-e storm windows and R-5 patio doors is located and their address for purchasing purposes.

    Good evening Irving -

    Have you had a chance to visit There you'll find many qualified manufacturers participating in the Volume Purchase Program with windows available. I would recommend using the Open Big Request Form on the site in order to quickly hear back from window vendors about delivery and pricing. Thanks,

    Low E glass is excellent for thermal efficiency in windows, in the UK argon gas now is becoming standard thus increasing energy saving
