There are many different types of windows with many different appearances that appeal to a wide range of housing styles and personal tastes. Before choosing doors or windows based solely on style, consumers are wise to make sure the products they select are energy efficient and easy to maintain. A home's doors and windows can greatly increase energy bills if they are not designed to current engineering standards. They should be carefully sized and installed well to prevent energy leaks.
