Installing new windows is a great way of improving indoor natural lighting, which brightens the mood inside your home and gives the illusion of a larger space. Of course, sunlight can be too much of a good thing. Too much heat gain can increase your utility bills, for instance.
To prevent too much heat from accumulating in your home, Renewal by Andersen® of Denver recommends choosing replacement windows with Low-E4 glass.
What Is Low-E4 Glass?
Low emissivity or low-E glass is coated with a thin, transparent coating that reflects heat from the sun. By preventing heat transfer, windows with low-E glass can reduce your heating and cooling costs (25% to 30% of which can be traced to heat gain or loss through windows) and improve indoor comfort.
How to Choose the Right Low-E Glass
In addition to checking if a low-E window is certified by ENERGY STAR®, you should check its energy ratings. The U-value gives you an idea of how well a low-E window can prevent heat transfer while the SHGC indicates the amount of sunlight that can pass through a window. The lower a window’s U-value, the better its insulative capabilities. And the lower the SHGC, the less heat that can pass through the glass panes of your window replacement.
