DRAINROOF - Modern Solution Against Extreme Cementification of Roof Garderns

PROTECTION OF THE SHEATH from the sudden temperature changes, from the UV rays and from the atmospehric agents. The coverage life grow of the 20%. LOWERING OF THE RUN-OFF PEAKS, a roof garden absorbs the 50% of rainwater, lowering the quantitiy to dispose in the urban sewer MICROCLIMATE REGULATION through the evaporation and evapotranpiration of the absorbed water, in order to refresh the environment. INCREASE OF THE COMMERCIAL VALUE, the roof garden offers new usable spaces and increases the the energy profit of building’coating INCREASE OF THE PHOTOVOLTAIC PROFIT thanks to the maintenance of a more stable temperature, within the range to obtain an high profit THERMAL AND ACOUSTIC INSULATION, the green set is used as an insulating layer: in winter it isolates thermally, while in summer it is used as a solar shield.

DRAINROOF is the drainage and accumulation element for the creation of roof gardens on slabs and plates made of concrete. It was specifically designed for green roofs because it offers an high rainwater disposal capability, avoiding stagnation and protecting the waterproofing layer. DRAINROOF high load capacity allows the creation of any type of garden, extensive light gardens and more usable intensive gardens. The panel has two different heights, 6 and 2.5 cm and allows the aerated crawl space to grow and they also help to limit the coverage thickness.

The typical application of the extensive roof garden is the green roof, which is created with plants that does not require manteinance and irrigation as the sedum and other similar species. These plants need a limited thickness underlayer: the set is light and can be installed on any existent roof, both plane and inclined. The extensive set is easy to realize and mantain and guarantees all the advantages of the green roof gardens. It absorbs most of the rainfalls, protects the coverage and isolates the building thermally. Keeping a stable temperature, it can improve the yeld of the photovoltaic panels which are
generally pulled alongside.

The intensive roof garden can be used as a real garden. Therefore, it requires a stratigraphy capable of housing high-stem trees because the set thickness is large and the slab can easily sustain an heavy load. It is certainly a more expensive solution in terms of manteinance and realization, but at the same time it guarantees many performance benefits. An intensive roof garden is able to absorb an high quantity of rainwater in order to better manage the water in the housing and urban areas. It can be used as a isolating layer, lowering the peaks of heat during summer and as a thermal insulation coating in winter.
