1. Are your windows single-pane?

Even with a storm window on the outside single-pane windows do little to insulate against heat loss. U-value is the measurement used to determine the amount of heat loss through windows (a lower number is better). The U-value of a single pane window is generally between 0.70 and 1.5 or even higher! However, the U-value of a high-grade, well constructed, double or triple pane window will range between a 0.20 and a 0.33.  With heating prices at an all-time high, properly insulated windows will save you money today, tomorrow and for years to come.

2. On colder days does the room feel drafty near the windows?

You may have been in homes (or even own one) where the curtains will move on a windy day or there’s an unmistakable chill in the air. This is a sure sign of heat loss. What’s replacing the cold air seeping into your home through and around your windows? Your heat, or a better way to put it, your hard earned cash. Even in younger homes with double-pane windows, low-grade materials and poor workmanship by the original installer means heat loss for you. Having double pane windows in itself isn’t good enough anymore. Homeowners are replacing more double pane windows now than ever before.

3. In the winter does frost develop on inside of your windows?

This is a dramatic sign that you are losing significant energy through your windows. The cold air is passing through the windows to the extent of freezing the moist air on the inside of your rooms. A properly constructed double or triple pane window creates a dead air space, or a buffer zone of sorts, between the frigid outside air and the warm room. That space significantly reduces the amount of energy transferred through the window opening.
