Window and door screens, composed of frames, mesh, splines, and spline rollers, form effective barriers against insects. They come in fixed, retractable, roll-up, hinged, and magnetic variations, each with unique mechanisms and applications. Common materials include fiberglass, aluminum, stainless steel, vinyl, and wood, offering varying durability, cost, and aesthetics. Hardware like tension rods, spacers, and brackets ensure secure installation. Accessories such as UV protectants, cleaners, and repair kits enhance functionality and longevity. Screens are sourced from hardware stores, home improvement centers, manufacturers, and handyman services. Homeowners and renters benefit from their insect control and ventilation abilities, creating comfortable living spaces.
