Beyond their attractive visual nature, Green Roofs offer many undisputable benefits, both ecological and economical, provided they are built with the right system. Increase Rainwater Retention Improve Noise Protection daylight    ^O Green Roofs cool and humidify the surrounding air. Thus they contribute to improving the microclimate in urban centres. This cooling effect significantly increases the performance of air-conditioning systems, reducing carbon emissions. Green Roof vegetation helps to filter out dust and smog particles. Nitrates and other harmful materials are absorbed by the plants...

There are two basic types of Green Roofs with a number of variations. Extensive landscaped roofs are an ecological alternative to conventional surface protection or ballast layers such as gravel and pavers. They are lightweight and have a shallow Build-up height. Suitable plants include various Sedum species, herbs and some grasses. They cope with the conditions on the roof (sun, wind, drought, etc.) by nature. After establishment of the vegetation, the maintenance is limited to one or two inspections a year. Extensive Green Roofs ■ minimal maintenance required - inspection 1-2 X / year - supply...

Vegetation layer and system substrate Filter layer Drainage layer Protection layer Roof construction Waterproofing The Challenge When designing and installing a Green Roof it is important to provide a growing environment as close as possible to the plants' natural environment. The most important issue is to compensate for the lack of subsoil. The answer is the ZinCo technology ZinCo systems are able to retain the necessary quantities of water to support the plants, while draining off the excess. The required amount of water is determined by the plant type, the geographical region and the roof...

Extensive Green Roofs As a general rule, flat roofs should be laid to fall of at least 2°. This is particularly important when designing an extensive Green Roof with a shallow drainage and substrate layer as any deflection in the deck allowing water to pond above the drainage layer will be harmful to the plants. However, Green Roofs can be installed on zero degree roofs where deeper puddles remain, provided that the correct build-up is designed to avoid the danger of drowning the plants. The standard System Build-ups for extensive Green Roofs are to be adapted to these requirements. By using Floraset®,...
