Marley Alutec has launched Elite, a multi-purpose flat roof and balcony drainage system that is compatible with all waterproofing membranes and roof build-ups.
The Elite outlets have been engineered to deliver a flow performance of up to 19l/s, reducing a project’s rainwater pipe and underground drainage requirements reducing the cost.
The membrane has a compression clamp design combined with high-performance butyl sealing rings, securely locking 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 air tight seal and thermal break between the outlet body and connecting pipework, to prevent cold bridging.
They have also been tested to a rainwater design depth of 1m, far above the typical requirement of 35mm.
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.
