Window screens serve multiple purposes, including providing insect protection by keeping pests out while allowing fresh air to circulate. They improve ventilation and can offer UV protection, reducing harmful sun exposure and protecting interior furnishings. Energy-efficient screens help regulate indoor temperatures, lowering energy costs. Privacy screens obscure the view from outside, enhancing privacy without blocking the view from inside. Security screens add an extra layer of protection against break-ins. Pet-resistant screens prevent damage from pets and keep them safe. Screens can also reduce allergens like pollen and dust, improving indoor air quality. Aesthetically, customizable screens can enhance a building’s appearance. Environmentally, some screens are made from sustainable materials. Retractable and magnetic screens offer temporary and portable solutions.
