Simonton Windows® is proud to participate as a qualified vendor in the U.S. Department of Energy’s R-5 Volume Purchase Program. Homeowners can realize substantial energy savings by purchasing these highly energy-efficient windows and doors. Research indicates that R-5 windows can reduce the average heat loss through windows by as much as 40 percent.
What is an R-5 Window? R-5 windows are highly insulating windows with a whole-window R-value of 5 (or a U-factor of around 0.2) and are the top tier of energy-efficient windows for cold and mixed climates available today.
What is an R-value and U-factor? An R-value indicates an insulation's resistance to heat flow. So, the higher the R-value, the greater the insulating effectiveness. U-factor is the inverse of R-value. So, the lower the U-factor, the better the thermal performance of the insulation..
