How to Make Windows More Energy Efficient

Making a few upgrades can help you save on monthly energy costs.

Windows provide a view to the outside world from our homes, but they also play a key role in our household energy costs. Poorly fitted or insulated windows allow too much air to come in or out, raising your overall energy costs. Learn ways to make your windows more efficient and save on your heating and cooling costs.

Things You'll Need

• Window frames
• Caulk
• Weatherstripping
• Window coverings

Instructions

1. Replace your window frames with fiberglass or vinyl frames. Older window frames made from wood are much less energy efficient than newer frames. Fiberglass is the best option, but may be difficult to find.

2. Apply caulk around the edges of your windows to help insulate your windows. Older windows tend to be fitted more poorly than newer, energy-efficient windows. Applying caulk can help you overcome the poor fitting and reduce lost heat and air.

3. Replace old weatherstripping. After years of use, weatherstripping wears down. Deteriorated weatherstripping can reduce insulation and allow more airflow, raising your energy costs.

4. Install window covers or drapes on the inside of your window to help slow down heat loss or heat gain. Look for window coverings with high insulation ratings for best results.

5. Consider shutters or a window awning on the exterior portion of your door to reduce the amount of heat coming in.

Tips & Warnings

• It may be better to replace older windows with modern, energy-efficient ones. Newer, more energy efficient windows have special coatings applied to them to help insulate better, along with double and triple-pane designs.
