Benefits of Efficient Dual-Pane Windows
Comfort: Energy saving windows conduct less heat and reduce infiltration in the home. The comfort difference can be felt both during the summer and winter.
Energy Savings: Windows typically account for 10% to 25% of the exterior wall surface area. They usually contribute 25% to 50% of heating and cooling costs. Energy efficient windows help reduce this cost.
Moisture Control: Condensation often occurs on old windows because their surface temperature is so cold. Energy-efficient windows have a higher insulation rating (lower U-factor) and remain warmer, thereby eliminating condensation on the windows. This affects efficiency, indoor air quality and the structural integrity of your home
Reduced Fading: Ultraviolet (UV) radiation from sunlight can fade color from organic materials such as draperies, carpeting and wood furnishings. High efficiency windows with Low-E glazing can prevent 85% of the sun’s UV rays from entering the home.
Noise Reduction: Dual pane windows reduce transmission of outdoor noise, making your home quieter. The difference can be significant, in particular noise from vehicle traffic on streets is dramatically reduced.Convenience: modern windows have tilt-in features that allow both sides to be easily cleaned from inside.

Which Window is Right for Me?
If you have decided to install energy saving windows, then perhaps you have done some research and noticed that there are numerous types, brands, models and designs to choose from. Every manufacturer touts their special features and claims that they have the best performance window. How do you know if the replacment window you are buying really does have the best performance? Fortunately, the research has already been done for you:
NFRC Window Energy Performance Rating
The National Fenestration Rating Council (NFRC) is a non-profit organization that administers a uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Any mainstream window or door will have a NFRC energy performance label.
“The energy performance label can help you determine how well a product will perform the functions of helping to cool your building in the summer, warm your building in the winter, keep out wind, and resist condensation.NOTE: All energy performance values on the label represent the rating of windows/doors as whole systems (glazing and frame).”
Expert Guidance for Home Windows
When helping you decide on the right window for your home, AHE will go over the ratings of the windows we recommend and show you how they compare to other window options. This is the only way to compare the performance of windows and make an educated decision.
