The Science Behind Hunter Douglas Products
Without energy-efficient window treatments, as much as 50% of a home's heating and cooling energy can be lost through its windows. All Hunter Douglas window fashions provide window insulation, offering your home increased protection against heat loss during the winter, as well as minimizing the sun's heat or "solar heat" during the summer. More specifically, here's how Hunter Douglas products help conserve energy at the window:
Window treatments reduce heat flow (both heat loss and heat gain) through the windows. It's a scientific fact that heat is attracted to cold. In winter months, indoor heating moves toward and escapes through windows to the outdoors, while in summertime, the outside heat flows into your home through these same windows. Many Hunter Douglas window fashions help insulate homes; helping reduce energy consumption, save on heating and cooling costs, and creating a more comfortable room setting.
Solar Heat Control
Window treatments help to control solar heat (heat generated from the sun) by allowing it into your home in the winter and minimizing the amount that comes in during the summer. The warmth provided by the sun, its solar energy, may be desirable during the winter to help heat your home, yet it can make a room overly hot and uncomfortable while driving up air conditioning costs in the summer. Many Hunter Douglas products are designed to reduce the amount of solar heat that passes through the window, which is known as the Solar Heat Gain Coefficient (SHGC). The lower the SHGC, the more protected your home is from the sun's heat. To enjoy the sun's warmth when desired, simply raise or open the window fashion and invite it in.
Window treatments enhance daylighting (the use of natural light) by diffusing and dispersing sunlight deep into a room, reducing your need for electrical lighting. Daylighting is the practice of lighting rooms with natural light rather than generating illumination from electricity. With Hunter Douglas window fashions, you can control how much natural light comes into your room. Our sheers and other select styles actually diffuse light as it enters and help to draw it deeper into the room. You can also direct incoming light where it's needed most by titling the louvers, slats, vanes, blinds and panels. By drawing natural light into a room many of our window treatments reduce your energy needs for other types of lighting.
Just as sunscreen protects our skin from the sun's damaging ultraviolet (UV) rays, window treatments protect our room interiors and add to the lifespan of valuable possessions. Virtually every Hunter Douglas product filters out at least 75% of the sun's harmful UV rays when installed over double-glazed glass windows. Many products provide even greater protection, up to 99%, when fully lowered and with slats, vanes or louvers in the fully closed position. The rating of Good to Excellent to Superior for a product will partly depend on the fabrics and product features you choose and whether your window covering is opened, closed, raised or lowered.
A History of Energy Efficiency
Hunger Douglas is an industry leader in making a big energy savings difference at the window. In 1985, they invented the highly energy-efficient Duette® honeycomb shades in response to the energy crisis of the late 1970s. More recently, they introduced Duette Architella® honeycomb shades, which offer superior energy efficiency thanks to their patented honeycomb-within-a-honeycomb construction, and Vignette® Tiered Architella Shades, featuring rear fabric air pockets that trap air and create an extra layer of insulation.
