Can New Windows REALLY Reduce Heating & Cooling Costs?

New windows and doors are great to look at, easier to operate, and can give your home a whole new look. But did you know they can also help reduce your monthly energy bills by 30% or more?

Studies by the U.S. Department of Energy (DOE) found that up to one-third of the energy generated in a typical home – heated air in the winter and cooled air in the summer – can be “lost” through inefficient windows and doors. Few of us can afford to sacrifice that much energy or waste that much money.

What is an “inefficient” window or door? A window or door that allows radiant energy to “pass through” from the inside of your home to the outside acts like a sieve, through which passes your hard earned money! Most windows and doors manufactured more than 10 years ago were not made to meet modern efficiency standards. The materials used in the frame, sash, and glass area simply are not sufficient to create an energy barrier.

Other culprits are windows and doors that are improperly installed, creating gaps that allow the free exchange of air. You might as well just leave a window open all day and night! Poorly fitted doors and windows are especially prevalent among “off-the-shelf” models you’ll find at local hardware centers.

The solution is to install custom-fit windows and doors that are properly sized for your home, and installed with proper sealing to prevent leaks. Today’s windows and doors are also made with amazingly efficient materials that work to create an effective barrier to prevent the exchange of radiant energy.

For example, the glass in the Renewal by Andersen® windows our company installs is a multiple-pane “sandwich” made up of two separate panes of glass, separated by a gap that is filled with inert gas. Sound technical! What the combination does is prevent almost all radiant energy from entering or leaving your home.

Of course, the glass alone won’t do the job. That’s why Renewal by Andersen® makes its windows out of advanced Fibrex® material to further enhance insulation properties. The overall window package is among the most energy efficient available today.
