  • The DIADEM Green Roof Systems are specialized multi-layered systems certified by the EOTA European Technical Assessment in accordance with the ETA approval 17/1015 and have been successfully tested in many projects in Greece and abroad.
  • All products are CE certified and comply with international certification standards (DIN, EN ISO etc.) as stated in the FLL 2008 guidelines.
  • The DIADEM certified systems are recognized by international and European building certification standards, such as LEED, DGNB and BREEAM. Examples include the Athens College, which is the first Platinum LEED building in Greece, and the new Agemar office building in Kallithea (also a Platinum LEED award winner).
  • DIADEM products are characterized by innovative design details and have been designed to present many technical advantages.
  • The specially designed DiaDrain drainage cell layout allows the maximum amount of water to be retained and be delivered to the plants during the dry summer days. Additionallly, the perforated surface of the DiaDrain cells allows for proper ventilation of the roots. DiaDrain 25H, DiaDrain 40H, Diadrain 60H achieve maximum water retention compared to other drainage systems, making them ideal for achieving goals in international rating systems.
  • The DiaDrain drainage is produced from recycled polystyrene which is highly resistant to high temperatures and therefore most suitable for the Greek climate.
  • DIADEM systems are easy and quick to install and have a full range of products (the largest on the market) for every detail and solution.
  • DIADEM systems have maximum weight bearing capacity, and are suitable for rooftops with heavy footfall and for use by heavy vehicles.
  • DIADEM Green Roof Systems support the installation of a variety of built elements (built constructions, decking, paving, ponds).
  • The SEM and SRM special plant growth substrates are very light, non-compressible, have the necessary organic material for plant growth, provide ideal root ventilation and meet FLL guidelines. They carry laboratory analysis according to the standards mentioned by FLL.
  • Experience in the largest projects in Greece and the most complex constructions.
  • DIADEM Green Roof Systems are reliable and low-cost for their excellent quality.
  • DIADEM systems and products are specially designed to maximize energy saving and to avoid 'heat bridges'.
