Vacuum PVC single-ply membrane water attenuation blue roofing system for warm roof constructions.
Can be laid on roofs designed for slopes with a minimum 1:100 towards the outlet. Suitable for new build and refurbishment applications on flat or pitched roofs. Can be used on concrete roof decking, plywood WBP to BS 5268-2 and BS EN 636-3 and roofing Grade OSB to BS EN 300, Grade 3.
Water attenuation blue roofing system for new and existing roofs, which includes Protan BP 1.8 mm thick roofing membranes, manufactured from PVC with a core of polyester reinforcement. To be installed as exposed roofing, allowing rainwater to accumulate to a predefined maximum level and be stored on the roof for a certain amount of time after rainfall. Water run-off is then gradually permitted into the into the drainage system of the building before entering the drainage network. This avoids water overloading, which can result in flooding. Joint welds are carried out using hot air.
