ACO High Performance Rainwater Outlets

ACO Building Drainage

Flat Roofs
The past few years have seen major advances and improvements in the materials used in modern roofing technology. A specifier now has renewed confidence to take full advantage of the benefits flat and low-pitched roof designs can offer.

Flat roofs provide opportunities for planning and design flexibility, for example; terracing, roof-top gardens, patios, car parks, delivery areas, building services and ventilation equipment and the ability to add additional storeys at a later date.

Large area roofs or irregular shaped buildings can be completed more quickly, easily and cost effectively than a pitched roof.

Flat roofs also allow easy access to natural light and because of the simple construction, internal partitioning is easy and particularly advantageous for commercial or industrial buildings.

All ACO Building Drainage High Performance Rainwater Outlets are manufactured from die-cast marine-grade LM6 aluminium silicon alloy. This grade of aluminium alloy is highly corrosion resistant, weather-proof and resistant to ultra-violet radiation.

All cast components are polyester powder coated. For additional protection, this tough and resilient powder coated finish prevents natural galvanic corrosion in applications where dissimilar metals are dressed into the outlets. 304 stainless steel fixings are used to ensure long-service durability and reliability.

All ACO Building Drainage Rainwater Outlets are available in leaded gun metal to BS EN 1982:2008 to special order for lead or copper-clad roofs or connection to copper pipework.

ACO Building Drainage Car Park Gullies are manufactured from grey cast iron for robust and durable applications to accommodate heavy and frequent vehicle loads.
