The patented high-performance roof drainage system from CGL offering increased building protection and up to 60% reduction in outlets and downpipes. RainPulse is also the only push fit solution in the UK.
The RainPulse outlet is specially designed to maximise the efficiency of moving rainwater from the gutter into the downpipe. This is achieved by removing the vortex action created by air entering the downpipe during heavy rainfall.
The outlets efficiency has been tested and its capabilities are incorporated into our design software that allows CGL to design the relevant amount of drainage outlets and pipes to suit each project. The drainage outlets have been tested at the University of Sheffield to BS-EN 1253-2;2003 and complies with BS EN 12056-3 2000

No. RainPulse is the only high performance single stack rainwater management system available on the market which drains from the gutter outlet directly into the ground drainage. No high level (horizontal) pipes are used.
Gravity fed drainage systems are restricted by the natural vortex of water that takes place and the limiting factor of the down pipe. The British Standard EN 12056 states the because the vortex of water creates air, the pipe is limited to a filling capacity of 1/3 water, 2/3 air. The RainPulse rainwater outlet has been designed with an anti-vortex plate which restricts air from getting into the pipe when working at maximum capacity, allowing the pipe capacity to be maximised (3/3 water).
On a comparable roof the RainPulse rainwater management system (gutter, outlet, downpipe & installation) should at least be on parity with a gravity fed drainage system and will show a significant saving when compared with a siphonic drainage system.
Yes. Tested by The University of Sheffield. The system has been tested to UKAS calibration for flow calculations / debris effect and to BS EN 12056 for membrane clamp test, crush stability test, heat test and also independently by UKAS Calibration for flow rig test capacity to analytical design program.
The Rainpulse rainwater management system was launched in 2009 and is sold all over the world. CGL are the licence holders for the UK.
Yes. Contact firstname.lastname@example.org for suitable drainage contractor depending on location / project size.
No. Standard plastic PVC pipes cannot be used, only HDPE pipes or Aluminium pipes can be used.
No. Each RainPulse stack works to 100% capacity during the pulsing phase leaving no capacity in the stack for another outlet to be added.
The British Standard BS12056 part 3 states drainage overflows should not be included as part of the overall roof drainage calculations, however good working practice would be at least to have a tell-tale overflow per run.
No. The RainPulse rainwater management system does not have any moving parts.
CGL will perform roof drainage calculations based on information supplied by the customer, alternatively, customers can register for our free roof drainage calculation software – GDT2. To sign up for the roof drainage calculation software click this link.

Running rainwater naturally makes a noise, however RainPulse rainwater management will create no more noise than a gravity fed drainage system.
The Honda and Hyundai car dealerships at the Cheshire Oaks Retail Park in Ellesmere Port were conceived by architecture firm Mountford Piggot. The buildings were designed to be energy efficient as well as visually appealing, a feature that was achieved by utilising the CGL Gutters' outlet.
CGL Gutters is a part of Merson Group - a design and innovation led group of businesses that helps designers and brand owners create more valuable and visually striking building environments for their customers.Launch website
