During the winter:
- Reduce drafts by installing a heavy-duty clear plastic sheet or film to the inside of the window frame.
- Install tight-fitting insulating window shades on drafty windows
- Open your curtains and shades during the day to allow the sunlight to come in and close them at night to protect against cold drafts coming in.
During the summer:
- Window shades, drapes and blinds should be white and installed to reflect heat away from the house.
- South facing windows should have reflective film or sun-protective treatments to reduce solar heat.
- Awnings can be added on the south and west facing windows.
- Close the curtains/blinds on the south and west of the house during the day.
It may, however, be more cost effective to do a total window replacement and upgrade your home with all new, energy-efficient models. Of course, this is dependent on the age of your home and the inefficiency of your existing windows. When properly selected and installed, energy-efficient windows practically pay for themselves with the savings in heating, cooling, and lighting costs.
