Choosing windows based on their potential for energy-efficiency can help a family feel cooler in summer, warmer in winter, and greatly affect energy bill costs throughout the year. A window’s frame materials and glass coatings can work in your favor if you are interested in keeping your home comfortable while also conserving energy. By understanding some of the window styles and features available on the market, you can make informed decisions when selecting models that work with the outside elements and assist you in controlling your indoor temperatures.
Windows Featuring Low-Emissivity Coatings
To keep your Delaware home warm in winter and cool in summer, consider selecting windows that feature low-emissivity, or low-E, glass. This coating is so thin that it may be difficult to detect with the eye, and it typically contains a layer of metallic oxide on at least one surface of the glass of the window pane. These windows are capable of blocking up to 90% of the sun’s rays and function by controlling the manner in which sunlight transfers heat energy through the low-E coating. One of the many benefits of low-E glass in summer is that the coating reduces sunbeams while still providing daylight to come through the windows, and residents can enjoy clear views of the outdoors through the glass. Several insulating glazing choices are available, including gas fills, tints, reflective coatings, and other styles.
Ratings for Energy Performance
When selecting windows with superior insulation in mind, remember that a window’s U-value should be an important consideration. A window with a high U-value provides less resistance to heat flow and does not insulate as well as a product with a low U-value. Since a window’s U-factor range is usually between 0.20-1.20, you may opt for a window on the lower end of the scale if optimum insulation is important for your residence.
Window Designs
The style of your Delaware home’s windows can greatly affect energy-efficiency. Casement windows featuring a crank that allows windows to swing outward are excellent for keeping out the cold winds in winter. Although picture windows don’t open, a resident can improve their ability to be energy-efficient by choosing models outfitted with a glass type that promotes improved insulation.
Frame Materials
A window’s frame materials can determine their energy-efficiency a great deal. Because an aluminum frame acts as a rapid conductor of heat, it may not be a good choice for a homeowner looking for an energy-efficient alternative for cooling. Vinyl window frames act as excellent insulators, but the material’s tendency to expand and contract due to changes in temperature can leave gaps for hot or cold air from outside to enter a residence. Fiberglass window frames don’t have some of these issues, however their higher cost can put off some individuals looking for energy-efficient windows.
