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

Icopal 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.

Description

Icopal Filter Fleece is manufactured using UV stabilised high tenacity polypropylene providing high tensile properties and improved durability. The Icopal Filter Fleece allows water to drain through the membrane, whilst limiting the passage of fines and debris from the green roof system.

Icopal Filter Fleece should be installed with minimum 150 mm laps to ensure full surface coverage. The fleece should be rolled out in an advancing manner and should be secured immediately with the specified green roof system.
