BRITISH AND EUROPEAN STANDARDS
The Bauder green roof landscaping components and waterproofing systems are created from products tested to meet internationally recognised guidelines.
The waterproofing membranes are certified under FLL (Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau), which is the benchmark test for root resistance in Europe and has been for the last 20 years.
RAIN NOISE TESTING
The Bauder Xero Flor Sedum Blanket Green Roof System on a metal deck has been tested in accordance with BS EN ISO 140 -80: 2006 to determine the sound intensity level within the building during heavy rainfall. A figure of 33.5 dB was achieved, which is almost certainly sufficient to gain a credit under Point 5 of section Hea 13 of BREEAM Education 2008 for most projects.
The Bauder XF301 sedum blanket has an EXT. F.AA (flat roofs) and EXT. S.AA (sloped roofs) rating awarded to the entire system for zero spread of flame and no fire penetration. Tested to BS 476 Part 3 External Fire Exposure to Roofs as covered by European Standard DD ENV 1187:2002.
