How Do Dual Pane Insulated Windows Save Energy in NJ, NY?

One of the most popular and common replacement window products available to consumers is dual pane, also known as insulated, windows. Although dual pane windows are no longer considered new technology – they’ve been around for many decades – they’re still one of the best products for helping consumers save money and conserve energy in the home.

Dual pane windows have a simple but brilliant design that helps insulate the home from extreme temperatures outside. If you’re considering having dual pane windows installed in your home, this is what you need to know.

Single Pane Windows Vs. Dual Pane Windows

Single pane windows are windows that have been made with one pane of glass. Until dual pane windows became commonly available, single pane windows were the norm in homes around the country. The problem with single pane products is that one thin piece of glass provides very little insulation against temperature extreme. When the air outside is very hot or very cold, that single piece of glass transfers the temperature from the outside to the inside and the inside of window itself can get very hot or cold. This causes energy loss in the home and can make your heating and cooling system work harder and harder to keep inside temperatures comfortable for you. An over-worked HVAC system costs you energy dollars every day and can lead to premature breakdown of the systems.

Dual pane windows have two panes of glass and a pocket of gas or air in the middle. The space between the two glasses acts as an insulator that reduces the loss of energy between the home and outside. This can reduce the burden on your heating and air conditioning systems and lower your energy bills.

How Dual Pane Windows Work

Dual pane windows are typically made from energy efficient glass. Windows from Renewal by Andersen of New Jersey and New York Metro are made from high performance low-E4 glass that prevents heat from passing through the window.

In winter, this helps keep warm air in the home. In summer, this keeps warm air outside the home. The space between the two panes of glass serves as additional insulation from heat loss and can also help reduce sound from traveling from outside the home to inside the home.

Why It’s Important to Buy Quality Dual Pane Windows

While dual pane insulated windows almost always perform better than single pane windows, it’s important to ensure that the windows you buy are high quality. The better the construction and more durable the materials, the longer your windows will last and the more energy efficient they’ll be. High quality dual-pane windows are a better investment.
