Chilly days are ahead, and it might be time to get ahead by replacing your old windows! Energy efficient windows ensure that your heating and cooling systems do not have to work harder than necessary and that you have lower electric bills and more consistent temperatures in your home. 

So what qualities matter in a window? Low-E (low-emissivity) regulates the amount of UV rays that filter into your home, keeping the heat gain low in warm seasons and allowing more heat in cooler seasons. U-factor is a measurement of the rate of heat transfer that windows allow. The lower the rating (on a scale from .20 to 1.20) the more effective the window is at insulating. Finally, Energy Star Rating is an indicator of how efficient your windows will be. All of these are qualities to ask about when you’re window shopping!
