flyscreen

A flyscreen is a mesh barrier designed to cover windows, doors, or other openings in buildings. Its primary purpose is to prevent insects, such as flies and mosquitoes, from entering the interior while allowing air to circulate. Flyscreens are typically made from fine mesh materials like fiberglass, aluminum, stainless steel, or synthetic fabrics, stretched taut over a frame. The mesh is woven or extruded with small holes that are large enough for air to pass through but too small for most common insects.

The design of flyscreens can vary. Some are fixed permanently to window frames, while others are designed to be removable for cleaning or seasonal use. Retractable or roller flyscreens are also available, which can be drawn across an opening when needed and rolled up when not in use. Door flyscreens often incorporate a hinged or sliding mechanism to allow passage while maintaining the barrier. The frames themselves are commonly constructed from aluminum or uPVC for durability and weather resistance.

The effectiveness of a flyscreen depends on the fineness of the mesh and the integrity of its installation. Gaps or tears in the screen can allow insects to enter. Regular cleaning is also important to maintain airflow and prevent the buildup of dirt and debris. Flyscreens are a common and cost-effective solution for pest control in homes and other buildings, contributing to comfort and hygiene by reducing the presence of flying insects.
