Highly Insulating R-5 Windows

The US Department of Energy (US DOE) is recommending that homeowners purchase highly insulating R-5 windows for their homes. According to the US Department of Energy's web site highly-insulating windows with a whole-window R-value of 5 (a U-factor of around 0.2)1 are the top tier of energy-efficient windows for cold and mixed climates available today. This compares to ENERGY STAR windows with an R-value of 3. Increasing the R-value from 3 to 5 reduces average heat loss through the window by 30% to 40%.

The US DOE is working with window manufacturers, such as National Vinyl, to offer competitive pricing on R-5 windows.
