This video demonstrates a DIY, or Do it Yourself, way to seal or insulate a window against the winter cold, drafts or wind and save on energy costs.

Transcript: Insulate a Window Against Winter

Hi! I'm Ami Young for About.com Home.

Why Insulate a Window?


Drafty windows can really increase your heating bill in the winter time, so today I'm going to show you how to winterize those drafty windows to save on energy costs.

What You Need to Insulate a Window?


For this project, you're going to need:
  1. A roll of double-sided tape
  2. A pair of scissors
  3. A blow dryer
  4. A box of window insulation (which you can usually pick up at your local hardware store)
  5. A clean work towel

Insulate a Window
First, you want to make sure that the edges around the frame of your window are nice and clean and free of dirt or debris. Wipe down the edges around the window frame, and if you havent cleaned this area in a while, feel free to use an all-purpose cleaner just to make sure the surface is nice and clean.

Next, after the area is clean, I need to measure out how much window insulation I'm going to use. To do this, I'm going to hold my piece of window insulation up to the window frame. I want to leave a good two to three inches overhang on both sides and on the top and bottom of the frame. Once you've measured it out, cut off the excess that you don't need.

Now, put this piece to the side in an area where the insulation won't get dirty or punctured because we're going to use it a little bit later.

Next, with only one side of the double-sided tape uncovered - I'm going to outline the perimeter of the window frame where I'm going to place my window insulation. This should go on in a smooth, straight line from the very top corners to the very bottom corners on each side of the frame, and from the very far left corners to the very far right corners on the top and bottom of the frame. Make sure that the ends of the tape connect because the tape is going to act as the seal for our window insulation.

Now that we have the tape on, we're ready to start sealing our insulation to the window frame. Start at the top and work your way down. First, peel off the outer paper of the double sided tape on the top of the window to expose the sticky side. Next, apply the window insulation evenly to the sticky side of the double sided tape, leaving 2 to 3 inches of over-hang on the top, left, and right sides. Once the window insulation is secured to the top of the window frame, evenly work your way down the left and right sides of the window frame, alternating between the left and right as you go down so as to avoid pulling more to the right than the left side or vise versa. Now, it doesn't have to be super tight, but it shouldn't be too loose either.

Once you get to the bottom of the window frame, peel off the paper on the last strip of double-sided tape, seal window insulation to the bottom, and double check to make sure that there arent any gaps or holes in the seal around the window.

Now, its time to make sure that our insulation is nice and tight so it doesnt come loose by the draft through the window. For this step, were going to use a blow dryer on a low warm setting and just start slowly working from the center of the window insulation outward. As you slowly work your way out, if you notice the air becoming hot, try to reduce the setting and move the warm air to a different area of the window insulation, as using too warm of a setting will tighten the insulation too quickly and possibly create a hole. Once the insulation has shrunk to a nice fit, check the seal again.

So there we have it! No more drafts and I can't wait to see my next electric bill!
