How to Improve the Energy Efficiency of Existing Windows

Your home’s windows provide some great opportunities to save energy. They can also be the cause of significant wasted energy. You could install more energy efficient windows in your home, but in the meantime,  improve the energy efficiency of existing windows with some tried-and-true tips.

Improving Existing Windows for Max Efficiency

1. Weatherization – Windows can be a major source of air leaks. When air from outside comes in through cracks, gaps and other leaks around windows, it wreaks havoc on energy efficiency. Weatherstripping seals up those leaks, keeping outdoor air out and the air from your HVAC system inside. You can also seal windows using rope caulk or a draft snake.
2. Window film –  Rather than install new windows that slow the transfer of heat, you can improve the energy efficiency of existing windows by applying a window film. Not only does it keep the heat out in summer and make things warmer in winter, film also filters out UV rays to help prevent sun damage.
3. Nail polish – If a window is cracked, you can give it a temporary fix with a careful application of clear nail polish. It’s nearly invisible, and once it dries, the crack is sealed up until you’re able to replace the glass.
4. Insulated curtains –  Insulated drapes are designed to keep warm air in during the winter and out during the summer. Using a high density foam, they prevent heat exchange with the outside while simultaneously blocking out sound. A vapor barrier helps drapes keep moisture out as well, which is a helpful feature in the humid Florida summers.
5. Storm windows – Orlando doesn’t get as many storms as cities nearer the coast, so if you have storm windows, it’s likely they don’t see a lot of use. However, if you repaint, reglaze and wash them thoroughly, they can cut drafts to your home and provide great insulation.
