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 Outdated or failing windows are responsible for a large percentage of the wasted energy in homes and other buildings.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.
CONSIDERING YOUR CLIMATE
Where you live affects which type of window or door is best suited for your needs. Depending on the climate, you may want to give more attention to certain performance measures over others.
In regions with cold winters, windows should keep heat where it belongs: indoors. That means you should look for windows that slow the transfer of heat, a performance measured by the U-Factor. The lower the U-Factor, the lower the rate of heat loss through a window.
In cold regions, your windows also can help you take advantage of solar radiation, which is free heat that eases the workload of your furnace or other energy-powered heat source. A window's performance in this regard is measured by the solar heat gain coefficient (SHGC). A higher number means a window will allow more heat to pass through.
Southern Climates and Intense Sun
In warmer areas and sun-soaked regions with year-round mild temperatures, your windows should perform the opposite duty. Here you want to keep heat out by choosing windows that reflect solar radiation. Less heat coming into the home means lower air-conditioning costs and a reduced carbon footprint. In these regions, a lower solar heat gain coefficient is a crucial to the window's energy efficiency.
