SEDUMIN green roof system
Greening system
in extensive lightweight construction For flat and slightly pitched roofs
System description
Thanks to its diffusion-open design, the Sedumin system can be used on all roof surfaces.
It is used for ecological, economic and constructional reasons, especially as a gravel substitute for
New buildings and renovations of flat roofs and slightly pitched roofs.
Weight:
approx. 42 kg/m2 (dry), approx. 70 kg/m2; (water-saturated)
with 4 cm substrate structure
Properties
- No maintenance necessary, only 1x annual inspection as with a gravel roof
- Areas accessible for inspection tours
- No irrigation necessary
- Drainage and water storage effect
- consists of only 3 components
- Very low weight
Vegetation structure
1) Sedum planting:
Site-specific plant selection, mixture of at least 6 different species/varieties
2) Sedumin extensive substrate:
Vegetation substrate with high water storage capacity,
low but sufficient nutrient buffering, high proportion of coarse pores
3) Sedumin water storage and drainage mat:
High water storage only through binding - no accumulation
Nutrient supply through Maltaflor fertiliser, filter and protective function
Substructure requirement:
Root protection layer according to FLL and V.f.B guidelines
Advantages
1) Energy saving:
The following values were determined on the basis of investigations by the Austrian Research Centre Vienna-Arsenal:
in summer 60% less costs for cooling
less heating costs in winter 20%
2) Low weight:
With a construction height of only approx. 7 cm, the Sedumin system weighs only
approx. 70 kg/m2; (if required, it can be extended to a gravel weight of approx. 130 kg/m2)
3) Great optics:
The Sedumin system is green throughout the winter. It is varied with fresh green
It sprouts in spring, blooms yellow-red all over in June and July and turns red-green in autumn.
4) No maintenance:
The sedum storage mat and the frugal nature of the sedum plants mean that no irrigation is required.
necessary. All other weeds die in the first dry period.
no mowing - no weed removal - no watering
5) Good dust binding:
The larger plant surface area than with moss cover or gravel provides many times more
Dust binding.
6) Recycled product:
The Sedumin storage mat consists of CFC-free, plant-compatible foam waste that is
can be bound without chemical agents.
7) Very good fire protection:
According to an investigation by the fire prevention centre for Upper Austria, burn-through is prevented.
8) Simple installation:
The Sedumin roof system consists of only 3 different components and can therefore be installed very quickly and cost-effectively.
