Heat lost through windows and doors represents a significant chunk of most heating bills. Some sources estimate that loss through windows alone could account for up to 35 percent of heating bills. If you are tired of watching your hard earned money slip through the cracks, there are things that you can do:

Consider the two important factors – U value – measures the rate of heat loss and the Solar Heat Gain Coefficient, current requirement for tax credit is .30 or less.

Check around windows and doors with a candle or a light piece of thread on a windy day to determine where drafts are. This will reveal problem areas in need of immediate attention.

Remove and replace damaged caulk and weather-stripping.

Decorate your windows with efficiency — closed shutters, window shades, blinds, curtains and lined draperies.

For a long-range solution, consider installing replacement windows, or storm windows and doors.
