Marley Alutec, the rainwater system manufacturer, has launched Elite, a multi-purpose flat roof and balcony drainage system that is compatible with all waterproofing membranes and roof build-ups. The launch is supported by the introduction of a unique online roof drainage design tool.
The Elite outlets have been engineered to deliver a flow performance of up to 19l/s, thereby reducing a project’s rainwater pipe and underground drainage requirements to achieve significant cost savings.
Said to be simple and fast to install, the membrane compression clamp design on Elite outlets, combined with high-performance butyl sealing rings, securely locks the waterproof membrane to the outlet body, ensuring a durable watertight seal.
The Elite outlets connect to all common PVCu, High Density Polyethylene Pipe (HDPE) and socketless cast iron pipework sizes, while all balcony outlets connect to aluminium (76mmØ and 72x72mm), PVCu (82mmØ and 11mmØ) and socketless cast iron (70mmØ and 100mmØ) pipework. PVCu pipe connectors provide an airtight seal and thermal break between the outlet body and connecting pipework, to prevent cold bridging.
Tested to ensure the ultimate in reliability and confidence, the Elite outlets have also been tested to a rainwater design depth of 1m, far above the typical requirement of 35mm.
“We identified a need in the market for universally compatible roof and balcony outlet products, so the Elite range was developed to make the specification process significantly easier, meaning our outlets are the ideal solution,” said Brian Bell, head of technical services at Marley Alutec. “The new range is manufactured from high-quality marine-grade aluminium, which gives an extensive life expectancy of at least 50 years. Well known for its durable characteristics, aluminium will never corrode or degrade.
“In addition to the new outlets, the launch is also supported by an online roof drainage design tool. This tool calculates the number of outlets required based on location and specification, ensuring full compliance with the rainwater draining design standard BS EN12056-3. This provides users with a full set of drainage calculations to confirm suitability of the product, as well as links to detailed product specific information. As always, our dedicated Technical Services department will be on hand to assist with any queries.”
