Investing in energy-efficient replacement windows and doors is one of the best things you can do for your home. Aside from added appeal, they can save you on energy bills. These windows can help reduce your dependence on your heating and cooling systems. They help keep your home cool in summer and warm in winter. Modern improvements in window technologies also have paved the way for the development of units that can insulate four times better than standard windows.
Read on to learn more about features that make windows energy-efficient.
Low-emissivity (Low-E) glass features a transparent coating that helps in reducing the amount of heat passing through the glass while still allowing natural light. This coating lowers the U-value of the glass, which defines how well a window resists non-solar heat gain or loss. Windows with lower U-value offers better resistance against heat flow and insulating value. Low-E coating on a conventional single-pane window can reduce solar heat gain but it can’t reduce conductive and convective heat flow.
No matter the climate, double glazing is an essential feature in high-performance windows. Together with low-E glass, double glazing provides the best thermal performance. The U-factor of double-glazed windows can go as low as 1.8, compared with around 5 in single-glazed clear windows.
Double-pane windows can block a significant amount of harmful ultraviolet rays, protecting your furnishings, flooring, and other valuables from fading. Multi-pane windows can also help you stay comfortable indoors all-year-round. These windows usually have gas fillings in the space between the insulated glass, such as krypton and argon.
Durable Window Frames
A window frame with a low U-value helps in reducing the overall U-value of the unit. Frames with timber, uPVC, or a composite aluminum or timber design perform better than standard aluminum windows by giving an advanced thermal performance.
Superior Weather Seals
Conditioned air can escape and leave your home through cracks and gaps around the frames and sashes of your windows. You can stop or avoid this problem by replacing your old bay windows with energy-efficient ones. Advances oxford window seals allowed for better performing units.
What to Look for When Purchasing Energy-Efficient Windows
When purchasing windows, always look for the ENERGY STAR® and NFRC labels. If you live in a cold climate, go for units with gas fills and Low-E coatings to reduce heat loss. On the other hand, those in warmer climates should choose windows with coatings to reduce heat gain. To get significant energy savings, choose widows with low U-factor and SHGC. Keep in mind that you should look for whole-unit U-factors and SHGCs instead of center-of-glass U-factors and SHGCs.
At Renewal by Andersen®, our windows are made for every climate. Our windows feature Fibrex® material frames and High Performance™ Low-E4® glass, making them more energy-efficient than conventional windows. Fibrex offers more insulation than other materials like wood and vinyl. This material is so strong that it can be made into thinner frames and any window style. It’s also guaranteed not to crack, warp, and rot.
Moreover, our High Performance Low E4 glass windows are 45 percent more energy-efficient in summer and 56 percent more energy-efficient in summer. We also offer SmartSun™ glass, which is 70 percent more energy-efficient in summer and 45 percent more in winter. This glass option can also block 95 percent of UV rays.
