In order to evaluate the compatibility of this layer, the followings must be checked: the quality of the material, its thickness, weight and tensile strength. Mechanical protection is necessary while building green roofs.Bauder Schutzmatte SM 6/SM 8/SM 10Materialpolyurethane-rubberThickness6 mm8 mm10 mmWeightca. 4,3 kg/m²ca. 5,7 kg/m²ca. 7,2 kg/m²ClassB2 according to DIN 4102Size1,25 x 10 m1,25 x 8 m1,25 x 6 mDelivery shaperoll of 12,5 m² or boardsroll of 10 m² or boardsroll of 7,5 m² or boardsItem number7793 00007792 10007794 1000Protective layer – GeotextileThis geotextile is made of polyester fibres, a mixture of mechanically reinforced fibres and regenerated polyester and polypropylene. It protects the waterproofing and the insulation of the green roof. It is able to absorb 3-6 l/m² moisture, depending on the product. The geotextile mechanically protects lower layers against drainage elements and also helps the uniform distribution of storm water, which was not taken over by the drainage layer.Bauder Faserschutzmatte FSM 600/FSM 1100Materialpolyester, polypropyleneThickness4 mm8 mmWeight600 g/m²1100 g/m²Water retention3 l/m²6 l/m²Size2 x 30 m2 x 15 mDelivery formroll of 60 m²roll of 30 m²Item number7450 06007450 1100Protective layer – Protective veilIt is made of recycled polyester fibres and protects the waterproofing and the insulation of the green roof.
