High Performance Roof
Drainage System

RainPulse is a 3rd generation high performance rainwater management system comprising of three key components: Gutter, Outlet & Downpipe. Described in NBS/NES R10 as a 'Pressure Assisted Rainwater System'.

The system performs as a gravity fed drainage system during light rainfall, as the intensity of the rainfall increases the outlets begin to pulse draining the requirements. As the rainfall intensity decrease the system reverts back to gravity fed drainage.
