Going siphonic
Akatherm siphonic roof drainage systems are engineered on the concept of full bore (a fill rate of 100%). This implies that rainwater flows at high speed through small diameter pipe work, at normally zero gradient.
This siphonic effect is created by the (kinetic) energy derived from the hydraulic head, caused by the difference in height between the roof outlet and the discharge point in a building. Specialist roof outlets prevent air being sucked into the system... Read more
At the heart of the siphonic roof drainage system, the roof outlet responds to negative pressure conditions in the system by streamlining the fluid flow, whilst preventing the entry of air. For every level of rain intensity, type of roof construction and roof membrane, you can choose a dedicated Akasison roof outlet.
