Icopal Protection Fleece is intended to provide a protection and cushioning layer to the green roof waterproofing membrane to prevent damage of the membrane caused by the green roof system above.
Icopal Protection Fleece is manufactured from high tenacity virgin polypropylene. Providing high tensile properties and improved durability. The increased drawing within the fibre manufacturing process re-orientates the molecules within the fibre making it considerably stronger. With the increased molecular orientation and associated higher density it increases mechanical properties and environmental resistance properties that are paramount for protecting waterproofing layers beneath green roof systems.

Ensure the waterproofing is clean and free of all dust and debris.
Prior to the installation of the green roof system, install Icopal Protection Fleece above the waterproofing membrane.
Icopal Protection Fleece should be installed with 100 mm side laps and 150 mm end laps to ensure full surface coverage. The Icopal Protection Fleece should also be turned up at all upstands and perimeters to ensure the waterproofing details are sufficiently protected. The fleece should be rolled out in an advancing manner and should be secured immediately with the specified green roof system.
Icopal Protection Fleece is supplied under a Quality Management System approved to ISO 9001: 2000 by BSI Quality Assurance.
Delivery and Storage
Icopal Protection Fleece is delivered in rolls secured with a wrapper. Rolls must be stored off the ground and on a flat level surface under cover and protected from weather and mechanical damage.
