To improve energy efficiency you may need to update or replace windows.Energy efficient windows are an important consideration for both new and existing homes. Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.
If you are selecting windows for new construction or to replace existing windows, it's important to choose the most efficient windows you can afford that work best in your climate.
If your existing windows are in good condition, taking steps to reduce the energy loss through windows can make your home more comfortable and save you money on energy bills.
Windows, doors, and skylights—also known as fenestration—are significant components in a home's envelope. Ensuring they are as energy efficient as possible can save energy; reduce heating, cooling, and lighting costs; and improve the comfort of your home.
