A blue roof attenuation system to be showcased by ACO Building Drainage at this year’s Futurebuild will help increase building resilience and futureproof performance during increasing extreme weather conditions, thanks to its unique patented design.
The system, which features in a new animation, operates as an open attenuation tank that functions independently of the roof’s waterproofing and drainage system.
During design rainfall conditions, the ACO blue roof attenuation system allows controlled drainage of rainwater on all roof types thanks to the attenuation tank sitting above a structural drainage layer.
In exceedance conditions the roof can drain quickly. This is achieved as the system allows water to discharge by an internal overflow, as well as around the perimeter of the tank. As a result, the system meets planning conditions and Building Regulations without compromising roof waterproofing – or overloading the roof structure. Additionally the system is compliant with Flat Roofing and Drainage building standards and the SuDS Manual hydraulic design guidance.
Suitable for both new build and retrofit schemes, it can be constructed on any new or existing flat roof where roof waterproofing has been applied. It is also ideal when used as part of a combined passive irrigation or active rainwater harvesting system.
Kevin Bohea Divisional Managing Director at ACO Building Drainage said: “One of the challenges facing most blue roof systems is the extent to which they can mitigate the building risk involved in holding water on a roof for extended periods.
“Conventional blue roofs come with increased risk of a water penetration which could cause long-term damage to the building structure. Our patented system removes this risk thanks to the separate attenuation tank, which essentially prevents the water encountering the waterproofing of the building during design events. We invite contractors, engineers and architects to visit stand A65 at Futurebuild so the benefits of the system can be seen in person.”
The blue roof attenuation system will feature at ACO’s Futurebuild stand A65 from 1-3 March. For more information and to view our new animation about the ACO patented blue roof attenuation system please visit www.aco.co.uk/blue-green-roofs.
