The All Season sun sail is the right choice for permanent installations. This extremely robust construction has a massive stainless steel three-way-turnbuckle for fixation in the corners. The surrounding edges of the sun sail have a strong stainless steel cable inside. Although the solid HDPE-Tentmesh is permerable for water and air, it still protects against up to 98% of the UV-rays. For this reason All Season sun sails are not only prepared for wind and weather (snow loads excluded), they are also the best choice for shading very large areas (up until 75 m²) and often used in kindergartens, retirement homes, lidos and in hospitality!
