HDPE is a woven mesh (often referred to as “shade cloth”) made from 100% round monofilament HDPE yarn. HDPE Shade cloth comes in a variety of tensile strengths, material weights, and shade factors and is used for a varierty of shade applications from agricultural to architectural.  Because of its open weave, HDPE membranes are not waterproof, so are primarily used for shading in hot climates. The material comes in rolls up to 3 m wide and is fabricated by stitching rather than welding. It has a life expectancy of 5-15 years, with warranties from 5 up to 15 years, depending on grade.
