While there are ENERGY STAR® rated windows out there, you may not be ready to have yours replaced. (And that’s totally fine.) When it comes to insulating your home in extreme temperatures, it doesn’t have to cost an arm and leg. In reality, there are tons of ways to block out drafts — while saving a pretty penny on your electric bill.

From weather stripping to window treatments, today we’ll be sharing six low-cost ways to insulate windows and doors.

1. Weatherstripping and Caulking

One of the most prominent reasons for high utility bills is air escaping from your home. The first order of business will be caulking the inside and outside of your window casings and using weather stripping in the sash. Weatherstripping can also be used for doors. It’s fairly inexpensive and is easy to install, all you need is to peel off the old weatherstripping and replace it with the new one every few years.

2. Window Treatments

Next, is the fun part. Not only does a good pair of curtains make your space look great, they’ll help insulate your home as well. Opt for blackout or heavier fabric curtains, they come in a variety of colors and can be paired with just about any type of decor.

3. Cellular Shades

Another option you can pair with your window treatments is cellular shades. Also called honeycomb shades, this window covering is composed of fabric folds which create multiple layers of air pockets. This, in turn, is similar to a down quilt for your windows.

4. Energy Film

Energy film, also known as insulation film is fantastic. It easily adheres to your windows, creating an extra layer of protection. A word of caution: your window may not be 100% transparent, but the film is clear for the most part.

5. Door Snakes

You may remember them from elementary school or even from your grandparent’s home. They may be a little traditional, but they certainly get the job done by trapping drafts under doors. A door snake is a small, stuffed fabric piece that lays along the base. Not only are they affordable, but they’re easy to make as well.

6. Storm Doors and Windows

This option is a little more expensive than the others on the list, but it really packs a punch. The Environmental Protection Agency has stated that adding a storm window to an older window that has been weather stripped provides the same or better energy savings as a new dual-pane window. So, if you’re looking for something heftier to get you through hurricane season, this would be a better bet.
