Window screens are a practical addition to homes, designed to block out insects while letting in fresh air and light. Constructed from mesh materials like fiberglass, aluminum, or polyester, these screens are an essential feature in homes, especially during warmer months. They fit snugly within window frames, allowing homeowners to keep windows open without inviting pests inside. Easy to install and maintain, window screens are available in various designs, including fixed, removable, and retractable versions. They are a low-cost and highly effective solution for improving home comfort and protecting against unwanted bugs and allergens.
