Drain
LGA-certified vertical drainage through the roof system with a flow-optimised gravel collection basket
Function
Molded part for vertical drainage through the roof assembly. Installation with connection to a piping system for water discharge or as an extension element for a roof drain. Ensure adequate backflow protection.
Material
Our drains are available in PVC, FPO/PP 1 and BIT for connection to the matching material used for the roof membrane. The materials are modified to be weather-resistant: UV-stabilised, against heat degradation and oxidative ageing as well as resistant to cold impact.
