Emergency overflow, rectangular
Quick emergency drainage of flat roof sections when the primary overflow solution is overloaded
Function
Emergency overflow with rectangular duct for quick horizontal drainage through the roof parapet – full drainage capacity from the outset! Free-flow installation. When installing the emergency overflow, the precise installation point depends on the water level.
Material
PVC and FPO/PP rectangular emergency overflows for seamless connection to the roof film. A version for bitumen roofs is also available. Liquid plastic is used for connections to bitumen roofs. The material compounds used are low-temperature impact resistant, weatherproof and stabilized against ultraviolet rays, oxidative decomposition and thermal aging
