Introducing the High Performance R-5 Window Program
What is the R-5 Window Program?
The United States Department of Energy (US DOE) has launched the “R5” Program to promote high-performance windows with exceptional insulation properties.
Top Benefits of R-5 Windows
- R-5 windows offer a whole-window R-value of 5 (U-factor around 0.2), making them the top choice for energy-efficient windows in cold and mixed climates.
- Compared to standard ENERGY STAR windows, which have an R-value of 3, R-5 windows reduce heat loss by 40%, significantly lowering energy bills.
Overcoming the Barrier: Cost
While R-5 windows offer superior energy savings, the primary challenge has been cost. The Department of Energy is working with the industry to reduce costs and make these high-efficiency windows more accessible to consumers.
