Suitable for the most commonly used tilt and casement windows with a maximum circumference of 500 cm, but not for sliding windows.

Perfect choice for sealing. The universal window seal is made of durable and thick 210T polyester with PU coating for waterproof protection. The window seal not only regulates the air exchange inside and outside the air-conditioned room, but also protects the cool indoor environment from dust and dirt, strong wind, sudden rain and insects.
