Icopal Filter Fleece used on green roof systems as a separation and containment layer

BMI Canopia Filter Fleece

Filtration layers are required in green roof systems as a separation and containment layer, to limit the amount of fine particles reaching the drainage layer and rainwater outlets.
They are also useful for encapsulating other components, such as telescopic drainage tubes, to reduce the amount of fines getting into them.


Endless Filter Fleece with tested water permeability as filter separation layer between drainage and substrate layers.

Intended use

Used as a horizontal filter layer on green roofs between the drainage layer and substrate and/or separation between peddle strips and substrate. Provides filtration or particles from the substrate. This is suitable for superstructural parts that can be walked on as a horizontal filter layer.
