Koster TPO 2mm Reinforced Membrane – For mechanical fixing systems
EPD
Certificate type
This environmentally friendly Warm Roof system is suitable for new build, refurbishment, and green roof projects. A range of membrane variants are available to cater for different fixing methods.
The membranes are suitable for direct exposure to weathering and can be used to waterproof unventilated and ventilated flat roofs, pitched roofs, green roofs, terraces, balconies, roof gardens, as well as for the waterproofing of underground garages and lining of tanks.
This warm roof waterproofing system based around the Koster TPO single-ply roofing membrane is suitable for a wide range of applications including new build, refurbishment of existing buildings or overlay of existing systems and is the ideal base for a green roof.
Other elements incorporated into this system include the Koster Vapour Barrier FR and depending on the selected variant, different adhesives and primers will also be used. According to the extensive fire testing carried out on this system, any PIR or PUR insulation board may be specified alongside this system.
This strong, robust, environmentally friendly and 100% recyclable membrane does not contain PVC or any other harmful chemicals therefore it will not contaminate water or planting, nor will it degrade over time.
It also offers excellent application characteristics, flexibility, longevity and is formulated for easy and uncomplicated jointing of the seams due to a wide welding temperature window.
