This production facility has been facing a challenge of weight restrains which is common on he metal roofs with long spans between the ribs. The traditional green roofs with sufficient storm-water handling capacity could not be implemented.


The lightweight Urbanscape Premium High Green Roof system has been implemented. It‘s design is focusing on good storm-water handling capacity which can capture up to 45 liters of water /m2 but still limiting weight to only 70 kg/m2 which is half of traditional green roofs with similar capacity.


The provided system can capture up to 60% of yearly rain water . The extremely good water holding consequently leads to higher evaporation during the summer months. Our performance evaluation study also shows good reduction of the temperature on the roof (more than 20 degrees less in peek summer) as well as lower solar radiation transfer in to the building.
