THE
ENERGY STAR® DIFFERENCE
If you like the idea of saving money on your heating and
cooling bills—and having a more comfortable home—then you'll surely
be interested in windows and doors that are ENERGY STAR® qualified.
Gorell
vinyl windows and doors that incorporate any of Gorell's six low-emissivity (Low-E)
insulating glass systems pass ENERGY STAR® requirements and therefore carry
ENERGY STAR® labels.
The ENERGY
STAR label can be affixed only to products that meet specific U-value and shading
coefficient ratings for one or more regions of the U.S. These ratings are
achieved through independent testing done to NFRC* standards.
