Energy-efficient windows are an investment to consider when updating your home. Not only will this save you in utility costs, it will also add value to your home when it comes time to sell. There are a few things you should know about energy-efficient windows and why it makes sense to install them.
What Makes Energy-Efficient Windows Different?
Efficient windows are constructed of sashes and frames that are either solid wood, vinyl, fiberglass, or metal. The latter three types are available with insulated cores to improve their performance.
The glass is double or triple panes with a space between each rather than a single pane. The glass itself is low-emissivity (low-e) that has a thin coating to deflect the sun’s UV rays while still allowing for natural daylight to stream through. The panes of glass have solid spacers between them to seal to form a tight seal. The cavities between each pane of glass are filled with argon or krypton gas that slows the transfer of heat through the window.
When choosing the right windows, look for Energy Star and NFRC ratings stamped on the glass. These ratings refer to the quality and performance of the windows.
Benefits of Energy-Efficient Windows
Efficient windows will make the interior of your home more comfortable by keeping drafts out and not allowing for heated or cooled air to escape. This in turn can save an average of 12% on your monthly utility bills.
If you are surrounded by noisy neighbors, traffic sounds, or loud landscaping equipment, insulated glass windows can greatly reduce outside noise and improve the quality of your interior space.
In addition to saving on heating and cooling costs and reducing noise, newer widows will protect your fabrics and finishes, such as draperies, carpets, furnishings, and wood floors. The sun’s UV rays will cause premature fading and discoloration of these surfaces. Low-e glass will prevent that from happening.
Cost of Energy-Efficient Windows
The cost of windows is dependent on several factors:
Size of the window opening
Choice of sash and frame material
Selection of double or triple panes
Style: picture window, grille patterns, rectangular or curved
Type: double-hung, casement, stationary, or sliding
Brand of window
You can expect to pay on average anywhere from $200 to $1200 per replacement window. The labor to remove old windows and install new ones can range from $25 to $60 per hour. A qualified window installer can often replace a window in an hour or less.
It is important to note that single pane windows are generally custom these days and are often required for historic or landmark designated buildings. The cost of such windows is often higher than that of energy-efficient windows.
Best Time of Year to Replace Windows
The best time of year to replace windows depends on your climate and your budget. Late spring and summer are the most popular times of year to replace windows due to more favorable weather conditions. However, choose late fall or winter to replace windows if you are trying to save money. Some companies may offer off-season savings incentives.
