If your home has old and/or inefficient windows, it might be more cost-effective to replace them than to try to improve their energy efficiency. New, energy-efficient windows eventually pay for themselves through lower heating and cooling costs, and sometimes even lighting costs.
When selecting windows for energy efficiency, it's important to first consider their energy performance ratings in relation to your climate and your home's design. A window's energy efficiency is dependent upon all of its components. Window framesconduct heat, contributing to a window's overall energy efficiency, particularly its U-factor. Glazing or glass technologies have become very sophisticated. Low-E glass ideally works to reflect the ultraviolet rays, reject infrared and keep your home cooler in a warmer climate. The Low-E coating reflects heat back to its source so it helps your home stay cooler in the summer and warmer in the winter. The coating won't scratch off because it is applied to the inside of the glass. It also helps protects against UV fading of any nearby furniture.
Argon gas is injected between the panes of glass to help prevent warm air from penetrating in the summer. Argon, a viscous, slow-moving gas, allows for less convection than would ordinary air, minimizing convective currents within the window and reducing the transfer of heat across the window.
Even the most energy-efficient window must be properly installed to ensure energy efficiency. Therefore, it's best to have a professional install your windows.
