During the winter months you may notice how well, or not so well, your windows work. If your home feels drafty or you continually see condensation build on your windows, you may own single-paned windows. Replacing single-paned windows with double-paned glass can do wonders for increasing energy efficiency in your home, not to mention moderating the indoor temperature better.
Look for double-paned windows with a low “U-value.” U-value measures the amount of heat lost through a material. Another factor to consider is “E-value” – the reflective value of a window to help prevent heat from escaping. Double-paned windows are rated for both U- and E-values. A low U-value (around 0.20) prevents loss through a window; and ideal low E- and U-value is rated around 0.35. Minding your Es and Us can help you moderate the temperature inside your home.
