WINDOW BASICS
A good place to start winterizing your windows is to investigate whether they need basic repairs or air sealing measures. If you've noticed a draft coming from one or more of your windows, you'll probably want to start by sealing the leaks with caulk, foam, or heat-shrinking plastic ? all available at most hardware stores.
Also remember that some styles of windows are more energy efficient than others. If your home has single-pane windows, you might consider investing in new high performance windows. Although new windows are an expensive purchase, they pay for themselves over time in lower energy bills. If you're ready to buy new windows, try these tips to find the best type for your needs.
WINDOW DRESSING
No matter what style of windows you have, they're often the weak spot in your home's envelope, because the glass doesn't slow the transfer of heat. To provide more insulating power, turn to insulated window coverings.
Commercial products. You can find many brands of shades and drapes that are designed to provide extra insulation for your windows. To compare products, look for window treatments that advertise their R-value? the higher the number the better the insulation they provide. (For context, check out this list of R-values for common building materials.)
Thermal drapes are easy to find online, but their performance can be hard to predict because it depends on how far away the fabric is from the window. In many cases you may want to choose insulated shades, which hang directly over the glass. Online sources for insulated shades include Window Quilts, Symphony Shades and EcoSmart Insulating Shades.
