and climate zones
A simple way for consumers, designers or architects to find premium energy efficiency fenestration products, is to identify products displaying the ENERGY STAR® symbol. Determine the zone where you home is located or a colder region to save even more on your energy costs.
and ecological footprint
Energy efficiency standards and programs will continue to impose products with high energy performance upgrades and will also consider the carbon footprints.
Our energy saving calculator has been developed from a heating and cooling calculator software created for residential buildings. It also relies on U.S. and Canadian certified energy efficiency data.
Common ENERGY STAR® windows only have a R-Value of 3. Increasing the R-value from 3 to 5 reduces average heat loss through the windows by 40% and saves consumer money on energy bills.
The Eco-Window product line will let you achieve these high levels of energy efficiency (from R3 to R5).
