There are many ways to save money on your monthly energy bills, from adding insulation in your attic to installing a zoning system throughout your home. However, it's important not to look the most obvious and visible means for heat to transfer in and out of your home, which is your windows. If you prefer not to go to the expense at this time of replacing your current single-pane windows with energy-saving double-pane windows, there are things that you can do to insulate single pane glass windows. While this will not be as effective as installing double pane windows from a company like Gilkey Windows, you will at least get higher efficiency than you are now. The following steps will show you how to do this.
What You Will Need
- Insulating Window Film
- Weatherstripping Tape
- Protective Gloves
- Tube of Caulk
- Caulking Gun
- Can of Expanding Foam Insulation
- Reflective Blinds
Step 1. Following the manufacturer's instructions, place insulating window film on your windowpanes. This is a clear film that covers the panes and helps to reduce heat from the sun from getting into your home. However, it doesn't block sunlight from getting inside. Make sure that you thoroughly clean and dry your windows before applying this film, or the film may not stick properly to the windowpanes.
Step 2. You should now seal any drafts that are coming in around your windows. Window drafts can significantly contribute to energy loss by allowing the conditioned air inside your home to drift outside, while unconditioned air comes pouring in from the outside. You can often feel these drafts on your bare hand. Solve this problem by applying weatherstripping tape to any small cracks around the window frame and sill where you detect a draft. Alternatively, insert a tube of caulk into a caulking gun and use it to seal any cracks you find around your window. Try to apply the caulk to the crack in one smooth, long bead.
Step 3. If you have large cracks or gaps, use a can of expanding foam insulation to spray foam into these areas. Don't overdo it, since this foam expands to fill spaces. Allow it to cure according to the manufacturer's directions.
Step 4. Hang reflective blinds inside your home to help keep direct sunlight from entering your home through the window. Keep in mind that reflective blinds are specifically designed for this, and ordinary blinds will not be as effective.
