Volatile energy costs have families looking for a smart, cost-effective way to lower household energy consumption. Properly installed weather stripping promises a low-tech, do-it-yourself way to improve your home’s energy efficiency and lower your environmental impact.

But does weather stripping really work?

Weather Stripping Energy Savings By-the-Numbers 

Weather stripping seals off drafts and air leaks commonly found around doors, windows, and vents. While not as obvious as an open window, leaving these small gaps unaddressed in multiple areas of your home could have the same effect on your home’s energy use!

Get this: Studies show that closing off those various leaks can lower your energy bills by as much as 30%!

Installing Pressure-sensitive Foam 

One of the most versatile weather stripping products is pressure-sensitive foam. It’s inexpensive and easy to install, though you may need to replace it every few years. One of the benefits of foam weatherstripping is its adaptability; it’s used to seal windows, doors and exterior vents.

It’s effective at sealing almost any gap as long as it’s installed correctly:

1. The adhesive backing on pressure-sensitive foam works best on warm days. Starting your project on a day when it’s relatively warm (starting at 60 degrees Fahrenheit) is perfect!

2. Thoroughly clean the surface where you plan to install the foam. Use soapy water if needed and be sure to dry the area before turning to your foam.

3. Measure the length of the window or door and double-check your work by laying out the foam and marking it at the correct length. Keep the backing paper on; we’re not ready to cut yet!

4. Cut the strip to the correct length with scissors.

5. Leave the backing on and lay the strip on the installation surface. If you can recruit another pair of hands, have your helper keep the strip flush against the windowpane or door jamb so there are no gaps.

6. Slowly peel back the adhesive paper a few inches at a time. Press the foam into place to keep it flush with the door or window gap.

7. At the far end of the installation surface, remove the last of the adhesive backing and stick the final section into place. Press the foam down firmly along the length of the door or window.

8. Repeat the process along other windowpanes or doors. Make sure the foam doesn’t impede closure. Try closing the door or window a few times, just to be sure!

3 Weather Stripping Quick Tips 

Ready to be the proud owner of a weather-stripped house? Here are three tips:

1. Inspect your weather stripping at least once a year. Replace any foam or seals that look cracked, torn, or otherwise ineffective.

2. When replacing weather stripping, petroleum jelly removes any “sticky goo” left by the old material.

3. Measure twice and cut once!
