ACO RoofBloxx ROOF ATTENUATION FOR BLUE/GREEN ROOF APPLICATIONS

ACO RoofBloxx is a complete roof attenuation system for blue, green and blue/green roofs. It enables engineers to create a drainage platform that gives architects the design flexibility required to create imaginative, multi-functional open green spaces at roof or podium level.

Comprising a shallow, high-strength, adjustable geocellular storage void and roof outlet flow control system, ACO RoofBloxx is fully compatible with ACO roof outlets, downpipes and surface water drainage systems.

When combined with the ACO Blue Roof Flow Restrictor, ACO RoofBloxx units can store rainwater at source to control surface water run-off. The system can also permanently store a percentage of the captured water for use in passive irrigation systems.

Hydraulic design guidance is provided as standard by ACO’s in-house technical design team.
