Solarline is a plain, silicone-coated fabric with an incredibly soft feel that will block out 100% of the light. Three layers of coating provide privacy as well as protection from the elements, such as sun and moisture. In addition, Solarline, unlike regular blockout fabrics, does not elicit or hold any dust. Solarline carries the Oeko-tex label and is therefore free from harmful substances and is safe for people and the environment.
