Insulating your windows can lower your home's energy use at any time of the year. Most people think about adding insulation during the winter, when they expect to use a lot of natural gas or electricity to battle cold weather. The right type of insulation can also help regulate your home's temperature during summer. Before you can get any benefits, though, you need to learn how to do the job properly. Start by trying these four ideas.

Keep Windows in Top Condition

Performing regular maintenance on your windows makes it harder for outdoor air to force its way inside. You should seal window leaks at least twice a year. Inspect areas around your windows for signs of cracks and damaged weatherstripping. If you find a crack, seal it with caulk. Replace damaged sections of weatherstripping to create an effective seal.

You can also keep your windows in good condition by doing the following:

  • Clean any mold or mildew you find growing near windows.
  • Use a dehumidifier to prevent condensation from warping the window frames.
  • .Install roller shutters to protect your windows from damage.

Add Layered Curtains

No matter what you do, some air may leak through your windows. Adding layered curtains creates a barrier that blocks outside air from entering your house. A thick curtain can offer similar benefits.

Installing layered curtains does more than just regulate your home's temperature. It can also make rooms more attractive. Choose designs and colors that complement your decorations, furniture, and walls.

Use a Draft Snake

An energy audit is the best way to find leaks in your home. If you don't want to spend money on an audit, however, you can take a cheaper route by slowly running your hand along each window's edges. A frigid or hot area, depending on the season, means that outside air is entering the house.

If you find a leak at the bottom of the window, you can use a draft snake to block incoming air. Most people use draft snakes along doors, but they work well with windows, too.

Draft snakes are perhaps the cheapest way to insulate your windows. You can save even more money by making them at home. It's unlikely that a single snake will solve the problem, but it will reduce the leak's size.

Install Window Insulation Film

Window insulation film is another inexpensive way to prevent drafts. Unlike thick curtains, they won't block the sunlight or your view, which is why some people prefer them. To install the film, do the following:

  • Clean your window and window frame.
  • Place double-sided tape along the frame (most kits come with tape).
  • Cut a piece of film large enough to cover the window, and attach it to the tape.
  • Use a blow dryer to shrink the film and create an insulating barrier.

You can find window insulation film kits at practically all home supply stores.

Properly insulating your windows can lower your heating and cooling bills significantly. By combining several of these options, you can minimize or eliminate drafts without spending a lot of money having new windows installed.
