There are two major parts to the changes in the ENERGY STAR Windows & Doors program that will occur on January 4, 2010.  The first change has to do with the four climate zones.  The borders of each zone have moved.  It’s important for you to know which zone you reside in. You can see the new map on the ENERGY STAR website (www.energystar.gov). It features a zip code lookup tool to help you find your area.

The other major change is an increase in thermal performance requirements—in the U-value and Solar Heat Gain values that products must achieve to qualify. 

So how will the new performance requirements affect you if you’re considering Gorell windows for your home?  If you purchase Eco Master or any of our triple-glass systems, there will be no change.  All of these high-performance glass systems will still qualify in all zones.

If you are considering AC Master, it will depend on which products you purchase and in which zone you live.  Some will qualify, but not all. Contact your Gorell dealer to determine which products still qualify with AC Master.

Starting on 1/1/10, Gorell’s laminated glass systems will incorporate our SolarControl Max Low-E—to ensure that every Gorell laminated glass system qualifies in all ENERGY STAR climate zones.
