How do I seal a drafty window?
Draft snake. If the bottom of your window leaks cold air, buy a foam-and-fabric draft snake kit. Cut the 36-inch foam tube provided to length and slip the washable cover over it. Then place the snake on the sill and shut the window on it to seal the deal.
Here are eight simple ways to draft-proof your windows and doors this fall:
- Use Weatherstripping.
- Install New Sweeps.
- Use Foam Tape.
- Apply Rigid Foam Insulation And Foil Stripping.
- Apply Window Film.
- Hang Insulated Curtains.
- Use A Door Snake.
- Re-Caulk Your Windows & Doors.
- Shrink Wrap. Enclose your windows with a layer of tight plastic to keep cold air out, and warm air in. Kits can be purchased at home repair stores for less than $7 at the time of publication. Wipe down the glass, frame and sill, as well as the wall around the window, to remove any dirt or dust.
- Here's how to insulate under a floor:
- Cut the insulation to length using a square and sharp utility knife.
- In older homes, where the spacing of the floor joists varies, you may need to cut the insulation to width as well.
- Install the insulation with the vapor barrier facing up toward the heated living area of the house.
- For a general sense of what spray foam insulation costs, if you choose an open cell product the cost can be roughly about $0.44 to $0.65 per board foot. A closed-cell insulation product can cost roughly $1.00 to $1.50 per board foot. These costs should be regarded as a guide only.
