PLANNING GUIDE System Solutions for Thriving Green Roofs

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 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 out of the...

Extensive Green Roof 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. The aim is, that these systems can 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...

_Vegetation layer and system substrate Filter layer Drainage layer 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 itself. Besides building the correct Green...

Extensive Green Roofs System Build-up “Sedum Carpet” The “Sedum Carpet” is a standard build-up for extensive Green Roofs. It is a shallow and lightweight Green Roof type with an attractive “back-to-nature” appearance, that requires little maintenance. Floradrain® FD 25-E is the appropriate drainage and waterstorage element for this system. It has the necessary compressive strength, a low profile height, little weight and is walkable. Proven Sedum species, in combination with the adapted substrate and System Build-up, guarantee a durable Green Roof. The System Substrate “Sedum Carpet” is...

Extensive Green Roofs System Build-up “Rockery Type Plants” Extensive Green Roofs call for plant communities that can easily deal with sun, wind and drought. The System Build-up “Rockery Type Plants” leads to an extensive Green Roof with sophisticated design and individual character. The substrate has a minimum depth of 80 mm and vegetation consists of various species which provide a long blooming period and set different accents throughout the vegetation period. Water and nutrients are mostly supplied through natural processes. Rainfall collects in the Floradrain® storage cells and roots...

Extensive Green Roofs The green roof build-up "Irrigated Extensive Roof" is a cost-effective solution for a permanent proper functioning of green roofs in dry climates. Automated irrigation of extensive green roof areas is very common in regions like the Mediterranean, as there are long periods of dry and hot weather. The climate is changing and as a consequence many regions more recently have to deal with increasingly long periods of drought. Without an irrigation system this can lead to species-poor green roofs and perhaps bare patches that are only temporarily green. Under such...

System Build-up "Irrigated Extensive Roof" Features: - Biodiversity and long-term greening success are achieved through targeted underground irrigation. - Irrigation takes place via special dripperlines which are fastened to the Aquafleece AF 300 at a distance of 500 mm. - Needs to be connected to an irrigation manager. - It is possible to seed grasses / herbal mixtures during favourable seasons. For this purpose, a top layer with 10 l/m2 of Zincohum is applied. Plug Plants FB 50 "Rockery Type Plants" or "Country Colours" System Substrate "Rockery Type Plants" from 80 mm Dripperline 500-L2...
