Contrary to popular belief, green roofs are a highly protective element of waterproofing. If well executed, it is a huge asset to the built environment. The thickness of the substrate, the insulation placement, the drainage and the type of plants must be properly dimensioned. This way, there is a contribution to a larger green environment, as well as an improvement on interior thermal comfort, as natural elements do not allow large temperature fluctuations, keeping the indoor climate at a constant comfort temperature.
