Window sail work refers to the installation and maintenance of window sails, which are aesthetically pleasing and functional coverings used to shade windows from direct sunlight while allowing natural light to filter through. These sails are typically made from durable and UV-resistant materials, like high-quality fabrics or engineered textiles, and are attached to the exterior of buildings. Window sail work involves precise measurements, secure mounting, and attention to design, creating a stylish and energy-efficient solution for enhancing both residential and commercial properties.
