OKNA Windows is proud to have been
selected to participate in the U.S. Department of Energy Building
Technologies Program for Highly Efficient R5 Windows. The
Department of Energy has initiated this program to promote windows
with U-Values lower than 0.22 (R5). ENERGY STAR windows only have
U-Value 0.30 (R-3). According to government research, lowering the
U-Value from 0.30 (R3 window) to U-Value 0.22 (R5 window) may
reduces the average heat loss through the windows by 40% and saves
money on energy bills.
Unfortunately, commercialization of
R-5 windows is hampered by cost. The Department of Energy is
working with leading manufacturers of high quality windows and
potential buyers to lower costs and make these energy-efficient
products more readily available.
“Last year I installed seven R5
windows in my house in OH. I also buttoned
up my insulation and stopped most air leaks as best as practical.
My gas
budget had been $220.00 per month for a couple of years. After 1
1/2
years it is now $77.00. We did not lower our thermostat. I am
upgrading
to more attic insulation and a newer high-efficiency furnace soon.
I am
interested in seeing what happens.”
