You’d be surprised how much more energy efficient your home can become if you replace your current windows with more energy efficient windows, or make energy efficiency improvements to your existing windows.
When you choose the right windows and install them correctly, it can go a long way toward minimizing your lighting, heating and cooling costs. There are three main things you should keep in mind when choosing windows with better energy efficiency:
You need to determine what specific kind(s) of replacement windows will work best in each room of your home for the highest levels of energy efficiency. Make sure you understand energy performance ratings for different kinds of windows (see this site
for more info).
You’ll also want to take into account the actual design of your home, including required window size and orientation, and the climate in which you live.
The energy efficiency level of a window is dependent on many factors, including the frame, the glass or glazing, and its operation (Is it an awning window? Hinged on the sides? A fixed pane of glass that doesn’t open?).
It is always best to have a professional install your replacement windows. There are many factors that contribute to a successful installation, including the window itself, the construction of your house, exterior cladding, and weather-resistive barriers. The windows must also be properly air-sealed with caulking to reach their maximum energy efficiency levels. Only a professional can ensure the job is done correctly.
If you don’t want to replace all your windows, you can also make some adjustments to your current windows
to make them more energy efficient, including adding storm windows to reduce leaking air and heat transfer, adding caulking and/or weather stripping, and using window coverings to reduce heat loss and/or heat gain.
