Rooftop water attenuation with Protan BlueProof & BlueProof Green

Using Protan’s single-ply thermoplastic roofing material, BlueProof makes it possible to turn a roof into temporary storage for stormwater. The water is gradually drained into the storm drain network during up to 24 hours, avoiding possible flooding. Protan calculates the attenuation and drainage using its BlueKalk tool, computing water depth, volume and weight per area. Blue Proof Green combines water attenuation with other solutions, like green roofs, solar roofs and rooftop terraces. The knitted roof membrane is designed to withstand heavy pressure and is 100% recyclable.
