Now that winter is here, the temperatures have begun to drop. Even if you don’t live in a snow-prone area, you’re likely cranking up the heat to ensure your home stays comfortable. Unfortunately, that can have major effects on your monthly energy bills — especially if you live in an older home. Because windows and doors account for nearly one-third of your home’s total thermal loss, these spots are the first ones you should evaluate. You could replace your windows, of course, or invest in better interior insulation. But there are also some quick fixes that can be highly effective. If you aren’t up for a major home renovation but want to minimize the draftiness throughout your house (and your high energy bills), here are some easy ways to amp up your insulation.

1. Apply Window Film: Apartment dwellers and homeowners alike may be familiar with this simple project. Insulating window film sticks directly to the window pane to act as an extra barrier. It’s important to note that after you apply the film, the pane won’t be as transparent. It may not be an option in certain spaces, particularly if the look of the film bothers you. Used in conjunction with other methods on this list, it can make a rather significant difference.
2. Add Weather Stripping: You can buy weatherstripping at virtually any home improvement store and easily install it to block out any drafts and leaks you’ll find. You should use weatherstrips in the sash of your window (the middle frame component with the locks). You can also use rope caulk around the edges to plug larger gaps.
3. Use Thermal Curtains: Window treatments can be a great way to quickly add some extra insulation. Insulated thermal curtains will keep the heat inside and the cold outside. Even opting for curtains in a darker, heavier fabric will help. Just make sure to let as much light in as possible during the daytime and close them when the sun starts to go down to maximize this natural heat source.
4. Opt For Cellular Shades: When you choose blinds for windows in your home, you won’t want to go with a basic model. Cellular shades, with their signature honeycomb shape, are designed to use air to your advantage. They actually act like a down comforter or warm quilt, insulating your windows and keeping the cold air away from your family.
5. Install Motorized Blinds: Whether or not you like cellular shades, you can make a difference by utilizing motorization. Motorized blinds for windows will automatically adjust the amount of light that comes in or out at a certain time or day without you ever having to lift a finger. This will make energy efficiency a breeze and will instantly optimize the amount of natural heat in your home. As a plus, motorized blinds for windows are also safer and convenient — and who doesn’t want that?

You might assume that adding insulation will require a huge renovation, but it’s actually much easier than you think to add an extra barrier or two. By following these tips, you can make your home more comfortable within a day (or a few hours!) and keep it that way all winter long.
