For use in the case of refurbishment with additional thermal insulation, where it is not possible to replace existing outlets. Uses the custom-fit refurbishment plate (DN 125 made of PP, DN 100 and DN 70 made of aluminium), which is flashed against the existing waterproofing without back flow. Flashing against the new waterproofing is carried out either with connecting flange and screw ring (refurbishment rainwater outlet 125) or with factory-fitted connecting flange (refurbishment rainwater outlet 75, 110).
Part of the roof and emergency drainage system for non-used or extensive green roof areas covered with EVALON® waterproofing membranes. They can be installed horizontally through the para-pet. Made of rigid polyvinyl chloride (PVC) and, depending on the version, are equipped either with a welding flange for EVALON® waterproofing membranes or with a factory-fitted connecting flange made of EVALON®. Along with the waterspouts for pipes with various diameters, rectangular versions are also available. These rectangular water spouts feature high discharge rates at low ponding heights.
