How Do Energy Efficient Windows Work?

You hear it all the time: “Replacement windows will save you money on your energy bills!” “Replacement windows will make your home more energy efficient!” – but how exactly do they help? If you have old, outdated windows, you may not realize how much energy (and money) you’re wasting because of your windows. Most old windows lack the premium energy efficiency features modern replacement windows have, causing your energy bills to skyrocket. Replacement windows from Window Nation come standard with top-of-the-line features to boost your home’s energy efficiency.

Energy Efficient Glass

If your windows are original to your home, you most likely have builder-grade single pane windows. Single pane windows have just one pane of glass, offering little to no insulation from the air outside. Replacement windows from Window Nation are available in a variety of glass options, giving your home the energy efficiency boost it needs.

If you’re looking to boost your home’s energy efficiency on a budget, consider replacing your windows with double pane glass. These windows have two panes of Low-E coated glass, offering premium energy efficiency at a wallet-friendly price. Double pane windows will block up to 80% of UV rays from entering your home, keeping your home comfortable while protecting your furniture and flooring from fading.

For maximum energy efficiency, we recommend replacing your windows with triple pane glass. Triple pane windows have three panes of energy efficient glass, keeping your home comfortable and well-insulated. These windows block 90% of UV rays from entering your home, keeping your home protected from sun damage. Triple pane windows are available in two options – Ultra and Ultimate – so you can choose the best fit for your home. If you’re looking for maximum energy efficiency, we recommend choosing Ultimate triple pane glass, offering the same benefits as Ultra triple pane glass but with additional protection from the sun’s UV rays.

No matter the window glass you choose, you can feel comfortable knowing you’ll be saving money on your energy bills year-round.

Low-E Glass Coating

Window glass is one of the most important parts of your replacement windows. Replacement windows from Window Nation have low-emissivity glass, also called Low-E glass, to keep your home feeling comfortable no matter the season. Low-E glass prevents damaging UV rays from passing through your windowpanes by reflecting sunlight and heat off your windows. This glass works to keep your home cool in the summer, reducing the strain on your air conditioner.

Low-E glass is coated with silver oxide, a cost-effective option that offers superior reflection capabilities. Together with the gas between your windowpanes, Low-E glass and silver oxide keep your windows well-insulated. Replacement windows from Window Nation have Argon gas between the panes to improve your window’s insulation, minimizing the transfer of heat through your windows. This gas helps keep the temperature of your window closer to the temperature in your room.

Spacer Systems

Window spacers play a critical role in keeping your home comfortable. Spacers separate the glass panes, playing an important role in determining how much heat or cold can pass through the windowpanes. Replacement windows from Window Nation use top-of-the-line Super Spacer technology, reducing the rate of heat loss through your windows. A rule of thumb when you shop for replacement windows: the lower the rate of heat loss, also known as the U Value, the greater the energy efficiency of the window.
