Sedum Roof Thickness

Sedum plants grown on matting will generate a loading of 60kg per square metre whereas a 10 15cm depth of growing medium for a broader range of plant species will generate a loading of around 250kg per square metre.

Sedum roof thickness.

An extensive green roof or sedum roof is a roof with vegetation that is more or less self perpetuating and that can further develop and maintain itself. This is also why sedums are so suitable as green roof vegetation especially on extensive living roofs. An extensive lightweight green roof system utilising a pre grown vegetation mat of 8 12 sedum species. Where a sedum roof is to be installed on an inverted roofs or other specially shaped roofs fitted with thermal insulation above the waterproofing attention.

This is the lightest weight all in one system available. Roughly speaking extensive green roofs have a substrate thickness of between 4 and 15 cm and a weight of 30 to 220 kilo per m2. Xf301 sedum blanket extensive green roof system when to specify. The cooling effect of the roof greening has the potential to affect the physical construction of the building so ensure that this risk has been assessed.

The system is suitable for both new build construction and retrofit refurbishment projects. It comprises mature sedum on 20mm of extensive substrate and incorporating a multifunctional water retention and filter layer. An extensive green roof or sedum roof is a roof with vegetation that is more or less self perpetuating and that can further develop and maintain itself. A sedum roof is a type of living roof consisting of a layer of vegetation that has been placed on a rooftop.

The vegetation is self sufficient growing and developing to provide protection absorb carbon dioxide and creating a point of interest. When sedum vegetation is applied to a green roof the weight is approximately 30 kg m2. Extensive living roofs have a very thin soil layer ranging in depth from 2 13cm 0 8 5in. Seek a professional opinion if there is doubt as regards the condition or load bearing capability of your proposed roof location.

The shallow soil layer is sensitive to the external environment such as temperature fluctuations and drought.
