Window screens are an essential feature of most homes, providing a barrier to keep insects and other unwanted pests outside while allowing fresh air to circulate. Made from durable, flexible materials like fiberglass or aluminum, these screens come in various types, including fixed, sliding, and retractable options. Installed in window frames, window screens are easy to clean and maintain, ensuring long-term functionality. By preventing the entry of mosquitoes, flies, and other insects, window screens help create a more comfortable indoor environment, especially during warmer months when opening windows is desirable. They are a simple yet effective home accessory.
