An insect screen (also called a fly screen or window screen) is a mesh barrier installed over windows, doors, or vents to prevent insects, pests, and debris from entering indoor spaces while still allowing air and light to pass through. It is commonly used in homes, offices, greenhouses, and outdoor structures.
