Benefits of using Energy Advantage Low E Glass
Reduction of Heat Loss in Winter. Energy Advantage™ Low-E Glass reduces heat loss to the cold outdoors by dramatically reducing radiant heat transfer and actually reflecting interior heat back into the room.
A Source of Free Energy. In addition to its low U-value, Energy Advantage Low-E Glass is optimized for winter performance and has a high shading coefficient. Compared to other low-E glass products with lower shading coefficients, Energy Advantage Low-E Glass allows more of the sun's rays to enter a home as solar energy to be converted into usable heat in winter.
Reduces Heat Gain in Summer. The same effect of keeping interior heat inside in the winter helps reduce the flow of hot outside air into the cooler interior in summer.
Lower Utility Bills. The bottom line is that Energy Advantage Low-E Glass helps reduce the number of heating and cooling Btus needed to keep a house at a comfortable temperature. That means furnace and air-conditioning systems work less, and that can add up to significant energy savings.
Reduction of UV Rays. Energy Advantage Low-E Glass significantly reduces transmission of the sun's damaging ultraviolet rays, one of the leading causes of premature fading and degradation of fabrics, upholstery and carpeting.
Comfort. Consumers want comfort and savings. No one enjoys sitting near a cold, drafty window in winter. Energy Advantage Low-E Glass works to raise the inside glass surface temperature in winter, to help minimize cold spots and keep homeowners more comfortable.
Minimized Condensation. Since Energy Advantage Low-E Glass helps keep the inside glass surface temperature warmer, homeowners can enjoy a more comfortable, higher humidity level with greatly reduced condensation and fogging.
Larger Window Areas. Because Energy Advantage Low-E Glass is an energy-efficient, high performance glass, architects, builders, and homeowners have the freedom to incorporate larger window and glass areas in their designs, without the resulting excessive energy costs.
Appearance. Energy Advantage Low-E Glass is one of the most color-neutral brands of low-E glass available. So, homeowners can enjoy the great looks as well as the great performance of windows made with Energy Advantage Low-E Glass.
If you're like most homeowners, you don't just want energy efficiency, you expect it. Almost any good-quality window you buy today incorporates insulating glass -- two pieces of glass with a sealed air space between them as a buffer between indoors and out. Combined with a wood or vinyl frame, insulating glass creates a window that outperforms most windows that were installed before the 1970s energy crisis.
To squash high heating and cooling bills, most window manufacturers offer such high performance options as low-emissivity (low-E) glass, which usually has a small additional cost. Low-E glass, which boasts the same visibility as plain glass, reflects heat and screens out the sun's rays, keeping your home cool and protecting curtains and carpets from fading. In fact, low-E glass is available today geared for both hot and cold climates, allowing you to customize your windows' efficiency depending on your climate.
Whichever type of low-E glass you choose, you often have the option of argon gas as part of the high-performance package. This heavy, inert gas is used in place of air between the two panes of glass to further enhance the window's insulating abilities.
Another feature manufacturers are highlighting these days is warm-edge technology. Instead of a traditional aluminum spacer between the panes of insulating glass, warm-edge windows use a spacer that doesn't transfer heat as readily. The overall improvement to a window's thermal performance is limited, but this feature reduces the condensation buildup on a window's perimeter, which can be a problem in some cold climates.
Looking for excellent efficiency and comfort? Ask these questions about the window you're considering:
·What type of energy options are available on this window? Some dealers forget to mention upgrades such as low-E glass, sun-control coatings for hot climates, or between-pane features such as pleated shades and mini-blinds.
·How does the window rate? Many windows carry energy-efficiency ratings standardized by the National Fenestration Rating Council. The National Wood Window Association and the American Architectural Manufacturers Association have window-rating programs that also factor in other performance measures.
·What warranty is offered, and who will back it?
·Will it be competently installed? Even the best-made window won't perform if the window opening is sloppily framed and poorly insulated.
If ease of cleaning is important, you'll want to make sure the windows you're purchasing tilt in or open so the exterior glass can be reached from the inside. This is particularly important for windows installed above the ground floor.
Also try the hardware. Does the window unlock, turn, and open easily? This is not only a good way to check the hardware, but you can get an overall feel of the window's quality by checking how it opens and closes. Even the appearance of the window gives you clues about quality. Examine the window perimeter to see if the seal of glass is neat. For windows with a welded frame, check the welds to see if they are tidy.
