When it comes to improving the efficiency of your windows, replacement is helpful but is not always the most cost effective solution. Replacement windows can cost between $500 per window for cheap (and worthless) vinyl to $1,000 per window for high end (and far more efficient) Pella or Anderson brands.
Several simple remedies can help improve the efficiency and comfort level in your home. Windows were originally designed to look good while letting in the light and the view. But old windows are lousy at keeping your home cozy. Please don’t fret . . . there are easy ways to improve the efficiency of your existing windows.
If you’ve got really old windows with sash weights, watch this video from This Old House to learn how to use a “spring balance” to replace that sash weight and leave room to add insulation in your window cavity.
In the meantime, check out these ridiculously easy and cheap solutions to make your windows a little more friendly this winter.
Solution #1: Window Treatments: Cost $0 (if you use your existing shades)
Window treatments are one of the cheapest ways to modestly improve efficiency. Keeping shades open can reduce the need for artificial lighting. But window dressings can also be used to reduce heat loss in the winter (at night), and heat gain in the summer (during the day).
Common energy-saving window treatments include interior blinds, draperies and shades. Interior blinds, either either horizontal or vertical, are a good choice because the slats can be used to control light and ventilation. However, this option is most effective in the summer months for reducing heat gain.
Draperies are effective during heating and cooling seasons, though their effectiveness is dependent on color and fabric. During the summer months, drapes should remain closed during the day to prevent heat gain. In the winter months, close all of your drapes at night. During the day, close any drapes that don’t receive any daylight to reduce heat loss. According to the U.S. Department of Energy, closing drapes during cold months can reduce heat loss in a room by up to 10%.
Shades are another valuable tool to combat both heat loss and heat gain. In the summer, lower shades on sunlit windows to reduce heat gain, and in the winter raise shades on the south side of the house during the day and lower them all at night. Dual shades which have one highly reflective side and one absorbing side, are extremely effective, because they can be reversed with the seasons. The reflective side should always face the warmest side, out during the summer and in during the winter. Utilizing window treatments is a good first step toward maximizing the efficiency of your windows.

Solution #2: Caulk: Cost $5
Products such as caulk, rope caulk and window insulation kits may also improve efficiency. Use caulk and rope caulk to seal air leaks in and around windows. Caulk is a lasting solution for sealing cracks and gaps that are about one-quarter-inch wide.
For a more flexible remedy, rope caulk can be applied in the winter and easily removed in the summer. Rope caulk can be used to seal airflow in window tracks, seals and any other drafty spots.
You can easily add some insulation to old windows that have sash weights. Check out this video from This Old House to find out how.
Solution #3: Insulation Kits: Cost $11.99
Finally, you can add a second layer of glazing to the inside of your windows with a plastic window insulation kit. By adding a buffer against drafts and extra sill air space you can cut down on heat loss and boost your home’s ability to hold heat. If installed and removed carefully, window insulation kits can be reused for several years.
Windows add to the character and appeal of a space. Replacing them can be costly and unnecessary. Before deciding to invest in replacement windows, try these tips to improve efficiency. Consider what the payback might be for replacing windows, and make an informed decision.

I tried out the window insulation on some old doors with single pane windows in them that let in so much cold air. The plastic was barely visible and I no longer felt the frigid cold draft every time I walked past one of these door. Good deal!

Window kits usually come with double-sided tape that leaves a residue that is very difficult to remove. Use something like this instead: http://www.amazon.com/18324-Seal-Removable-Caulk-10-1-Ounce/dp/B0002YVNOQ/ref=sr_1_1?ie=UTF8&s=hi&qid=1257633366&sr=8-1

What is the brand of rope caulk that is both removable and comes in white and brown? And where can I purchase it?

Lisa: Thanks for mentioning that rope caulk comes in white or brown to match your windows. Both Ace Hardware and Frost King sell rope caulk in brown to help blend with your windows.

Another benefit of the window kits is eliminating condensation that rots window frames and sills. Rope caulk can also be reused, though it may increase the likelihood that pieces of it will fall out behind the plastic insulating layer before spring arrives. Now, if only the plastic were tougher so that cat claws won’t immediately shred it.
