Extensive Green Roof Vegetation Mat: Veg Tech Sedummatta med biokol

The sedum mat consists of vegetation, a mineral growth media (substrate) containing biochar and a load-bearing structure (carrier) that reinforces the substrate and protects against erosion. The shrink free carrier consists of a three-dimensional loop network with a non-woven geotextile thermally bound on the underside and is stable over time. 

The growing media is optimized for the conditions that prevail on roofs. The use of biochar in the substrate entails soil-improving properties that are especially important for greenery in urban environments. Biochar is also a potential carbon sink. (See further information in section “Additional information”). The vegetation consists of drought-resistant species from the Crassulaceae family adapted to the Nordic climate The sedum mat is cultivated in open fields by Veg Tech in Sweden

Veg Tech Sedummatta med biokol has been assigned fire resistance class BROOF(t2) for roof coverings exposed to external fire in accordance with the procedures given in EN 13501-5:2016.
