When it comes to ventilation, there’s nothing quite as natural as just opening the windows and doors. Then again, opening windows and doors only makes sense if outdoor temperatures are comfortable and if the openings are protected by screens. Without screens, windows and doors in most regions are an open invitation to flies, mosquitoes, and other pests.

In areas where winters are severe, screens are generally stored away and replaced by storm windows; combination storm and screen windows that you can leave on all year long are an option that eliminates the need for storing screens. (See also Screens & Storms.

Window screens have a frame made of aluminum or wood. The screen fabric—typically aluminum or fiberglass—is stretched across the frame. Although window screens that are in good shape may be barely noticeable, screens that are dingy, bowed, or torn can be real eyesores.

In this section of HomeTips, you will find information on the many different types of screen fabrics and on how to install and care for window screens.
