GreenRoof

GREENROOF CONSISTS IN FITTING THE GREEN ROOF SYSTEM INTO A FLAT ROOF MADE FROM DOUBLE SKIN GROOVED SANDWICH PANELS. THE EXTERNAL SHEET IS COATED WITH A SPECIFIC PROTECTIVE, WATERPROOF FILM, IN PVC OR TPO (THERMOPLASTIC OLEFIN-BASED ELASTOMERS). THERMAL INSULATION IS GUARANTEED BY THE INSULATING POLYURETHANE OR ROCK WOOL CORE.

THERE ARE VARIOUS GREENROOF SOLUTIONS AVAILABLE DEPENDING ON DESIGN CHARACTERISTICS.

Utilization

Extensive GreenROOF:

Suitable for large buildings, sloping and existing roofs for their low substrate thickness (from approx. 3 to 15 cm), with a maximum weight of 100 kg/m². The colonising vegetation is very resilient (moss and beds, grass, succulents) and does not require frequent maintenance (watering only needed in the event of prolonged drought). Plants are no higher than 25 cm and mixing several varieties gives these roofs a multicoloured look that changes with the seasons. This type of roofing cannot be walked on or cultivated.

Even though weight and thickness are limited, the System’s considerable water collection capacity gives the plants used excellent vegetation conditions even during extended drought periods.

In the Mediterranean climatic area, just the water from the water supply, returned to vegetation through a capillary upwelling process, guarantees the system lasts from about three to seven weeks (based on the type) with no rain.

Irrigation is needed if critical periods last longer than three weeks (based on the type).

Intensive GreenROOF:​

For small and medium-sized surfaces. The substrate is larger (from about 15 to 30 cm) and the overload between 120 and 350 kg/m² (at maximum capacity in terms of water). It can accommodate vegetation with longer roots and a certain height like grass, lawns, perennials and bushes. Moderate maintenance and regular watering are needed. These can be compared to traditional gardens; any type of plant can be sown or cultivated.

The system requires irrigation facilities; running and maintenance costs can be compared to those of a traditional garden.

Due to the heavy load the roof is subjected to, careful design is fundamental for green roofs to guarantee perfect functionality and structure integrity. Capacity data in the load tables, on the following pages, are an estimate in standard use conditions and are not to be considered valid as design data.

The Designer will need to examine and check them, in order to identify the right size for the supporting underlying structures.
