Fleeces
Fleeces and layers fulfil different functions in roof greening. Their area of application is prescribed in various standards and directives. All fleeces meet the requirements of FLL 2018 and ÖNORM L 1131:2010.
Fleeces and layers are used to protect the roof waterproofing against mechanical damage, friction or the separation of material incompatible products (e.g. PVC and bitumen). Filter mats serve as a separating layer between the substrate and the underlying drainage layer to prevent fine particles from sludging into the drainage system.
