ARE CASEMENT WINDOWS ENERGY EFFICIENT?
By increasing the energy efficiency of your home, you can reduce your energy bills while also saving money and doing good for the planet. There are many ways to increase the energy efficiency of your home and replacing old windows is a popular method. When it comes to selecting new windows, you might be wondering “are casement windows energy efficient?”
Are Casement Windows Energy Efficient?
Casement windows are the most energy efficient style of window that is meant to be opened (picture windows are more efficient, but are designed to not open).
Casement windows offer such energy efficiency because of the design: these windows have a strong seal on all four sides. When a casement window is closed, the sash presses tightly against the frame so air cannot pass through. A strong gust of wind can actually press the sash and frame closer together.
Other types of windows are not designed to seal so tightly because of the way they open by sliding along a track. While modern replacement windows from Window Nation are all designed to be energy efficient, older windows in need of replacement can be a source of unwanted energy leakage.
When a window does not seal securely, air can leak in between the sash and the frame. In the winter, cold air from outside can leak into your home while heated air can escape. To stay comfortable, you'll need to turn up the thermostat. In the summer, the reverse happens, and you might need more air conditioning to stay comfortable. The more heat or air conditioning you use, the larger your energy footprint and the higher your energy bills.
Choosing Energy Efficient Windows
While casement windows are already highly efficient due to their design, you can make them even more energy efficient by selecting windows that offer certain traits:
- Low-e glass: Low-e or low emissivity glass coating is designed to bounce the sun's rays away from the home in summer, to reduce solar heat gain. The same coating reflects the heat inside your home so that it doesn’t leak through the window.
- Argon gas infill: Argon gas infills insert argon gas between panes of the window. Argon is less conductive than normal air, so it actually reduces the amount of heat or cold that passes through the window.
- Double/triple pane casement windows: Adding additional panes of glass to a casement window increases its energy efficiency by sandwiching more layers of insulating air or gas between the inside and outside of your home.
- Energy Star label: Look for the Energy Star label to indicate casement windows that are constructed using best design practices and energy efficient materials.
