THE ENERGY EFFICIENCY STORY
Windows and doors are key to your home’s comfort and energy efficiency. Outdated or failing windows are responsible for a large percentage of the wasted energy in homes and other buildings.
In the winter, windows can leak heat or block too many of the sun's warming rays -- meaning you burn more fuel and pay higher utility bills. In summer, poorly performing windows let cool air escape and fail to reflect outdoor heat.
Today’s windows and doors are far more energy-efficient than those of even 10 years ago. Modern, energy-efficient windows and doors can save you 15 to 25 percent on your monthly heating and cooling bills, according to the U.S. Department of Energy.
Where single sheets of clear glass once ruled the day, there are now windows with multiple glass layers. Special coatings on the glass reflect sunlight and ultraviolet rays without dimming the view. Gases injected between panes create extra insulation. Advanced framing materials and innovative design provide further efficiency gains.
Marvin operates at the leading edge of window and door technology. With Marvin, you can have it all -- products that look great and function flawlessly.
RATINGS: UNDERSTANDING ENERGY STAR AND NFRC
Until a few decades ago, measuring the efficiency of windows and doors was a patchwork of standards and manufacturers' claims. Doing an apples-to-apples comparison of different brands and models was next to impossible.
Today there are established standards that make it much easier to see how various windows and doors stack up against each other.
ENERGY STAR is a federal program that determines whether certain products -- including windows and doors -- meet energy-efficiency standards. Those that meet the performance benchmarks earn the ENERGY STAR label. Products must pass a rigorous, third-party review before they can earn the ENERGY STAR badge. Virtually all Marvin products have options that meet or exceed ENERGY STAR set guidelines.
The Environmental Protection Agency (EPA) has established a program to set guidelines for energy efficiency ratings. ENERGY STAR Most Efficient 2013 has set the criteria for Most Efficient, <=0.20 u-factor and Solar Heat Gain Coefficient (SHGC) criteria dependent upon region ranging from <0.25-0.40. Many of Marvin’s products meet the strict ENERGY STAR Most Efficient 2013 criteria. Contact your Marvin Dealer for more information on how to tailor your residential windows to meet criteria for your region.
The National Fenestration Ratings Council (NFRC) is a nonprofit, independent organization that rates and certifies the performance of windows and doors. This group ensures that makers of windows and doors use the same standards and testing methods when measuring the efficiency of their products. An NFRC label lists how a product performs in several efficiency categories. Marvin certifies its products through the NFRC.
