Commercial Shade cloth is a 100% Monofilament fabric. This makes it very strong and it has shade factors which have been accurately tested. Monofilament is essentially like fishing line which is knitted to form a very strong fabric. When cut it will not unravel due to its lockstitch construction. Commercial Shade cloth is made for the horticultural industry and is suitable for tension applications. Typically it has a 10 Year Warranty against UV degradation.
