Life on Roofs
Extensive landscaped roofs are an ecological alternative for conventional surface protections such as gravel. Regarding installation and maintenance they cause only small additional costs. Suitable plants are mosses, sedum-species, herbs and some grasses. After installation the maintenance is limited to 1 or 2 inspection checks a year. Most popular types of extensive green roofs:
"Sedum Carpet" is a low, ground-covering extensive green roof vegetation on a substrate layer of approx. 60 mm, which is mainly applied where - apart from low weight - also low maintenance costs are demanded.
The 6 or 7 different low-growing Sedum species which belong to the plant community "Sedum Carpet" are spread as shoots, or applied as plants with small root balls. The main flowering season of the "Sedum Carpet" is in early summer. The dominating colours are yellow and red/white.
In the "Rockery Type Plants" community, the different low-growing Sedum species mainly serve as ground cover. With the additional higher growing perennial plants, a creatively designed extensive green roof with an individual character can be realized. Especially the colourfully blooming ‘Dianthus’ species, like the Clusterhead Pink in the picture with a growth height of up to 400 mm, are acting as flowering eye-catchers throughout the whole year. The system "Rockery Type Plants" and the plant community of the same name stand out due to the fact that after the rooting period only very little maintenance work is required.
A thermal insulating landscaped roof is not only interesting for developing areas. Especially in case of redevelopments it is possible to leave the old thermal insulation in its place increasing the thermal property by installing an adequate Floratherm-element. So, it is possible to fulfil the air-to-air heat transmission coefficient according to the building standards. Dump and labour costs can be reduced.
