DOE R-5: A Window of the Future

Reduce the Average Heat Loss Through Windows by as Much as 40 Percent!

The DOEís R-5 Windows Volume Purchase Program is about more than just saving money

Cold and Mixed Climates like the Northeast demand performance form their Windows! R 5 Windows the top tier of energy efficient windows and are highly insulating!
DOE R5

R5 WIndows have an R-value of 5 (or a U-factor of around 0.2)

The R Factor

indicates a windows resistance to Heat Flow (The higher the number  the more effective the insulting factor).

The U Value

measures the rate of heat transfer (The lower the U factor, the better a window insulates.)

The US Department of Energy’s Building Technologies Program (BTP) is coordinating a volume purchase of R5 windows and low-e storm windows, to expand the market of these high efficiency products.

Price has been the principal barrier to more widespread market commercialization. The aim of this volume purchase initiative is to work with industry and potential buyers to make highly insulated windows more affordable.

Kasson and Keller, Inc is proud to be selected as a participant in the BTP VPP. We provide a wide array of products accepted under the DOE – R5 criteria for windows.
