The Roofs of the Future are Green Roofs are more than just “functional components” for the protection of the building structure. Roofs give character to individual buildings and entire city districts. Beyond that, roofs are more and more considered as open resource areas. They attract urban planners looking for socially responsible concepts that counteract the loss of natural living space and provide solutions for problems such as stormwater management and urban heat island effect in densely populated cities. Green Roofs are extending the formal language of contemporary architecture and confer...

Why have a Green Roof? Beyond their attractive visual nature, Green Roofs offer many undisputable benefits, both ecological and economical, provided they are built with the right system. Bind Dust and Toxic Particles 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...

Types of Green Roofs Extensive Green Roofs minimal maintenance required - inspection 1–2 x / year - supply of water and nutrients mostly by natural processes adapted plant communities - undemanding, drought-tolerant - self-regenerating little weight and shallow build-up height - mainly mineral substrate with depth up to 120 mm - weight approx. 50–150 kg/m2 surface protection with ecological functions 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...

Replicating Nature on Roofs Organic matter and topsoil Vegetation layer and system substrate Filter layer Drainage layer Bedrock 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...

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 particularly...

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 are...

Extensive Green Roofs System Build-up “Meadow Scents” on 0°-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...
