A door and window seal is placed around the perimeter of the window frame to ensure a seal between the sash and the frame. Its purpose is to seal the window, contributing to thermal and acoustic insulation, waterproofing, and protection from dust and infiltrations. Main functions of seals Thermal insulation: They prevent heat loss in winter and warm air in summer, helping maintain a stable indoor temperature and reducing energy costs. Sound insulation: They block the passage of outside noise, improving living comfort and creating a quieter environment. Waterproofing: They protect against the ingress of water and humidity, preventing damage and the formation of mold. Protection from dust and atmospheric agents: They block dust, pollen, and pollutants, keeping the environment cleaner. Compensation: Thanks to their elasticity, they compensate for assembly tolerances, slight material deformations, and hinge wear, ensuring a consistently effective closure.
