Emergency overflow, rectangular
Quick emergency drainage of flat roof sections when the primary overflow solution is overloaded
Function
Molded part for horizontal drainage or emergency drainage through the parapet. When installing, the exact installation point must be determined based on the water level.
Material
Variants in PVC and FPO/PP 1 for connection to the corresponding compatible material type of the roof membrane. Make the connection for bituminous seals using liquid plastic. The materials are modified to be weather-resistant: UV-stabilized, resistant to thermal degradation and oxidative aging, as well as impact-resistant in cold temperatures.
1 Alternatively available in PE (roof membranes based on PE)
