System Build-up “Rockery Type Plants“ “Rockery Type Plants“ allows for an extensive green roof with sophisticated design and individual character. The “Rockery Type Plants“ substrate is applied with a minimum of 70 mm in depth. “Rockery Type Plants“ vegetation consists of a wide variety of species which results in a long blooming period and allows for different accents throughout the vegetation period. Sedum species and other perennials are primarily used as a ground cover. Drought resistant perennials add flowering accents and height to the design, Dianthus carthusianorum for example reaches...

On 0°-roofs where deeper puddles might remain, the standard System Build-up "Rockery Type Plants" is to be modified. By installing higher Floraset® elements (50 or 75 mm) the necessary distance to the water level is ensured. The green roof build-up will be somewhat higher but not heavier as these elements are made of extruded polystyrene hard foam and therefore have a negligible weight. The Protection Mat TSM 32 with its lower retention capacity is sufficient, as water from the puddles is made available to the plants.

System Build-up “Sedum Carpet” “Sedum Carpet“ is a shallow, groundcovering extensive green roof type. In moderate climates, it gets along with approx. 60 mm of “Sedum Carpet“ System Substrate. “Sedum Carpet“ is applied, especially if both, the load often bearing capacity of the roof and the expenses for maintenance, are restrictive. Proven sedum species, in combination with the appropriate system build-up, guarantee a long-lasting low maintenance green roof. The plant community “Sedum Carpet“ contains various lowgrowing sedum species. The main bloo- ming time is in early summer, with yellow or...

The bigger the roof area, the higher the costs. You can avoid this by omitting certain layers. However, this could be dangerous as certain functions that are important for the long-term proper performance of the green roof are no longer available. ZinCo, therefore, has combined a number of functional layers in one product. Fixodrain® XD 20 can be installed without an additional protection layer, due to its extremely large contact surface and bonding over a large area. The filter sheet is laminated directly onto it and it is installed in one pass. The elements are attached to each other by means...

For some roof areas, even the Standard Build-up "Sedum Carpet" is too heavy. The solution is a system build-up with Floraset® FS 75. Less substrate is required as it is not applied equally but mainly fills the gaps between the high studs of the element. Although they start growing mainly in those "planting pots" the Sedum plants still form a dense ground cover which is supported by mosses over the course of time. The build-up weight is approx. 60 kg/m2. In areas with little annual precipitation and also on pitched roofs either additional substrate which effects weight and build-up height is required...
