The Glass is More Efficient

If your windows are the same windows that were installed when your home was built, then they are likely builder-grade, single-pane windows. This single pane means that there is essentially no insulation from the air outside. Newer windows are double-pane, or even triple-pane, with gas between the panes. This means better insulation and improved energy efficiency.

In addition to more panes, windows now have coatings that help make them more eco-friendly. New coated glass offers exceptional efficiency, and is quite affordable. Note that not only do these advancements help keep your home insulated, but they can block UV rays that would otherwise cause your furniture to fade.

Low-E Glass Coatings Make a Big Difference

The type of window you have in your windows makes a huge difference as far as how energy efficient it is. When you choose new windows, they will have low-emissivity glass, which is better known as low-e glass. This helps to keep too much heat from the sun getting into your home on warm days. It is also what keeps the UV rays described above from getting into your home. The right low-e glass coating can help keep your home cooler in the summer, which reduces how hard your air conditioner needs to run – and can even mean you don’t need AC at all.

Low-E glass is coated with silver oxide, which is a very affordable option that reflects the rays of the sun and doesn’t allow them to come. Combined with argon gas that is between the panes, the total transfer of hit is minimal.

Window Spacers Play a Big Part Too

Window spacers are what actually separate the glass panes, which is essential to determine how much heat or cold air can get through the windowpanes. The right spacers can lower the heat loss from the window. The heat loss, also known as the U-value, is measured to give you the efficiency of any particular window. The lower the number is, the more energy-efficient it is.
