Energy-efficient windows just as the name suggests are designed to keep heated or cooled air inside of the home. Additionally, the insulation properties of these windows reduce the energy bills of the home.
An energy saving window will generally have high-quality window frames preferably composite, fiberglass or vinyl frames, two or more glass panes, argon/krypton gas to fill the space between panes, windowpane spacers, and low-emissivity (low-e) glass coatings. The gases between the panes will seal off air from entering or escaping from the home. The low emissivity glass coating controls the heat energy from the sun depending on how it is used. Low-e glass coating will allow/stop infrared and UV light without affecting sunlight.
It is time to replace old windows if they are leaky and your energy bills are rising. Single pane windows can be replaced with more energy-efficient windows to increase energy performance and comfort in the home. Installing Energy Star rated windows has been found to save between $125 and $450 in energy bills per year.
Difference between using energy saving windows and doors and not
The investment in new energy-efficient windows will account for a big difference in your heating and cooling bills in the long term. Check with your home window manufacturers if they offer energy-efficient upgrades which will be easier and slightly inexpensive. New energy-efficient windows will also increase the value of your property.
Energy Efficient Windows: Energy Star Rating
Any energy saving window should have the Energy Star logo which acts as a mark of quality. To earn the Energy Star logo, windows must meet several standards including:
- The windows must be double-paned or triple-paned and have a very low U-factor indicating their insulating properties.
- Energy saving windows for northern climates must allow in infrared light for heat generation in the home and trap in warm air in the home. This creates a greenhouse effect effectively keeping the home warm and comfortable in the cold climate.
- Energy saving windows for southern climates are designed to keep heat out of the home.
Always work with professional and reputable window installers since you will be making a big investment. An energy-saving window will only work effectively if it is installed properly. Work with Ottawa Valley Glass who provides warranties on their work, including energy saving windows.
