Extra drainage through the parapet, either free flow or through the pipe system
Function
Molded part for horizontal emergency drainage through the parapet. Installation with connection to a piping system for water discharge or free outflow. When installing, the exact installation point must be determined based on the water level.
Material
Variants in PVC, FPO/PP 1, and BIT for connection to the corresponding compatible material type of the roof membrane. 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.
