Green roofs can be grown on any pitch of roof, even vertical walls, however those with a pitch of more than 9.5° generally have specific design requirements in order to retain the water and substrate across the surface.
Platon Xtra has been used in pitched turf roof constructions for over 20 years. Aging tests indicate that the Platon membrane has an expected life of at least 50 years. The Platon membrane, the main component in the system, is manufactured from HDPE, a material that is water repellent and resistant to chemicals. The Platon membrane combined with other components, creates a complete Earth Covered Roof System.
Platon DE25 and DE40 membranes are designed for the construction of flat green areas on top of buildings and underground structures such as car parks and garages. They are laid between the waterproofing and soil layer. Their stud design provides an excellent function that combines drainage and water storage as one efficient system. Platon DE40 is designed for installation where high capacity water storage is required.
