ZinCo creates "Green roofing for the 21st Century." As a pioneer in this area, ZinCo has been consistent in treading the environmental path for over forty years. Providing permanently reliable green roof systems for all types of roofs, the top priority is to do so in an environmentally compatible way. ZinCo system substrates, therefore, are based on recycled, pure-grade clay bricks. Where possible, recycling materials are also used for drainage elements and protection mats. This is the case with the new Natureline system, which incorporates the renewable raw materials polylactid acid and bio-polyethylene into these elements. With the Natureline system build-up, bioplastics have found their way onto the green roof market where they will prove themselves as an alternative with a promising future.
