Nidaroof Blue Roof Rainwater Attenuation System
Rooftop Attenuation System for Blue-Green Roofs
Nidaroof forms part of a blue roof system designed for the storage and temporary attenuation of rainwater on flat roofs. Slow the rate at which rainwater is released from the roof and form part of a rooftop sustainable urban drainage solution (SuDS).
The Lightweight and Versatile Blue Green Roof System
Nidaroof is our product for rooftop rainwater retention and attenuation. The lightweight system offers a cost-effective blue roof solution suitable for a wide range of blue green roof designs. Nidaroof can be installed directly beneath pedestal paving systems and is suitable for use with intensive and extensive green roofs and roof gardens. The flexible Nidaroof system can be incorporated into a range of blue green roof designs and combined with our Geoflow and Nidagreen products or with other systems to meet the requirements of the project.
Suitable for Blue, Green, and Blue Green Roofs
Blue and green roofs are designed to make better use of rooftop space and they play an increasingly important role in sustainable urban spaces. Blue roofs are primarily designed to collect rainwater, before gradually and steadily releasing this rainwater over a 24-hour period following a storm event. This helps to guard against excess water and flooding and comply with local SuDS guidelines, particularly in city center locations. Nidaroof can be considered as part of the overall SuDS management for a building, with the honeycomb cell structure, allowing water to be stored for irrigation of vegetation and planters as well as attenuated and released at a controlled flow rate.
Blue Roof Solutions
Rooftop SuDS designs have weight and load implications and a structural engineer should be engaged at an early stage. There are also a range of different options available to the construction designer to achieve a blue roof depending on the surface finishes desired and the volume of water to be attenuated. Whatever the project the Nidaroof system offers an attractive rooftop SuDS solution.
