What is Energy Efficiency?

Benefits of Energy Efficiency

Energy efficiency allows you to decrease the amount of energy you use—without sacrificing comfort. In warm months, energy-efficient products trap undesirable warm air outside. Alternatively, in cold months they wrap your home in a blanket of insulation, keeping your heat inside and protecting your interior from cold drafts. Energy-efficient products offer a myriad of benefits, both economically and environmentally.

More Reasons to Go Energy-Efficient

Energy-efficient products save homeowners, businesses and large industries a significant amount of money every year.
When heating and cooling systems, appliances, and lighting products can reduce the amount of energy they use, fewer greenhouse gases seep into the environment.
Some energy-efficient products, such as windows and doors keep a home or commercial building much more comfortable during extreme weather conditions.
Here at Window World, we believe our customers should never have to sacrifice quality, comfortability or affordability. With our energy-efficient products, you can have it all.
