Despite an initial cost, the insulative properties of a green roof will pay itself off in savings from energy bills. Engineered to endure. %PDF-1.3 %����

0000017946 00000 n Extensive green roofs require low maintenance vegetation and many native plants from coastal and arid inland regions are suitable. Cup-style drainage sheets should be overlapped to eliminate gaps between sheets while other plastic drainage types should have adjacent sheets butted together. The existing roof may not be capable of supporting an additional load. This makes them a more expensive option but they have a wider scope for design and use. 0000003398 00000 n These style structures have been found across history because of their amazing insulation properties. xref 0000003536 00000 n Green Roofs for Healthy Cities works to develop standards in support of the further development of the industry. 0000196510 00000 n 0000172715 00000 n 0000052059 00000 n %PDF-1.4 %���� Jorg Breuning, owner of Green Roof Service LLC, together with Katrin Scholz-Barth, first introduced the German FLL-Guideline for the Planning, Execution and Upkeep of Green-Roof Sites to green roof consultants and companies in the USA in April 2002, during an ASTM subcommittee meeting in Pittsburgh, PA. 0000002996 00000 n It is vital that the protection of the building’s fabric and in particular its waterproofing is considered in the green roof design. 271 0 obj <> endobj 0000002916 00000 n 95 0 obj<> endobj Roofmeadow green roof system design and installation. 0000016214 00000 n

It starts with a waterproofing membrane, which is commonly followed by a root barrier layer, an optional layer of insulation, drainage layer, filter fabric, growing medium and finally, vegetation.In Australia, there are three major categories of waterproofing membranes: liquid applied membrane treatments, preformed sheets, including ‘single ply’ and integrated systems.Liquid applied membrane material can be made from bitumen emulsions, modified bitumen, polymer cement systems, polyurethane, polyurethane modified acrylic, acrylic or two-part polyurethane hybrid elastomers.
