Ways to Insulate Large Windows

Weather Stripping

• Weather stripping is foam on a roll. It comes in different widths to fit all types of windows. This weather stripping is easy to apply, as it has an adhesive back. Measure a section of the window, such as the length of the side, and cut a strip to that length; peel off the backing and apply. Since the weather stripping has an adhesive back, clean the window casing where you will apply the stripping for best results. Debris or dust left on the window casings will impede adherence of the weather stripping.

Sheet Insulation

• Sheet insulation is added to windows to completely cover the glass. Since this product prevents looking in or out of the windows, use it on windows in rooms you don't use all the time, or cover the sheet insulation with decorative fabric to help it fit into the décor of the room. Measure the inside of the window frame and cut the sheet insulation using a utility knife. Press the sheet insulation into the window frame to block the cold air. Sheet insulation comes in 4-foot by 8-foot sheets, which fit just about any large window. Save these once you cut them to use year after year.

Plastic

• Plastic is another alternative for insulating large windows. Do this on either the inside or the outside of your home, just ensure you buy the proper type of window-plastic kit. The installation of plastic takes a little more time and is generally not reusable from year to year. The window kit comes with plastic sheets; check for your size windows before buying, along with double-sided tape. Place the tape along the outside edges of the window frame. Lay the plastic on the tape to hold it in place. Use a hair dryer to shrink the plastic and create a barrier from drafts.

Quilts

• For a quick and decorative way to insulate your windows, hang quilts in front of the glass. Double up the quilts and hang them over the curtain rods. It is necessary to have heavy-duty curtain rods, especially if your quilts are extra heavy. For best results, install the curtain rods to hang over the ends of the window casing. This allows the quilts to completely cover the windows, even where the casing meets the wall, which is where drafts are most likely to occur.
