What Is a Window Screen?

A window screen, also known as a fly screen, insect screen or mosquito screen, is a protective mesh installed on windows or doors. It allows fresh air to circulate while preventing insects, leaves and other outdoor debris from entering the building.

Window screens are widely used in homes, apartments, offices and commercial buildings to improve indoor comfort without restricting natural ventilation.
