Green Roof "Public Roof"

Utilization
variants

The Optigreen "Public Roof" system solution is subdivided into four variations,
depending on the intended use:
1.   Walkable surfaces ("Pedestrian")
2.   Accessible to cars ("Cars")
3.   Accessible to trucks, e.g. fire/emergency access roads ("Trucks")
4.   Green areas accessible to any kind of traffic ("Green")

Please select a variant

Substructure

The system build-up on Optigreen traffic roofs depends on the type and compression strength of the substructure:

Non-ventilated flat roof
constructions with high
density insulation

Roofs without insulation
(waterproof concrete)

Inverted roofs with high
densisty insulation

Inclines

Inclines are a further determining aspect in planning an Optigreen "Public Roof".

Variant 1

Support structure divergent
to the incline

Variant 2

Support structure integrated
into the incline

Variant 3

0° roof*

Different designs for support structure layers and, as a result, the respective Optigreen system build-up methods should be taken into consideration on the basis of surface drainage and roof incline (at least 2 % for pedestrian or 2.5 % for vehicular roofs).

Roofs with no minimum fall are not compliant with FLL recommendations and should therefore
not be designed as traffic accessible areas. The accumulation of water is unavoidable without
a fall.
The formation of ice particles can lead to the occurrence of frost damages, unless stilted surface
areas are installed to avoid the accumulation of water.

Further
information

Compression load capacity of insulation materials:

For load class 1 (pedestrian): minimum compression load capacity of the insulation material, i.e. = high compression load capacity as per DIN V 4108-10.
For load classes 2 and 3: verification of suitability for the intended use to be provided the manufacturer. See also "Recommendations for the design and construction of traffic surfaces on buildings" from the FLL (2005).

Protection of the roof membrane:
Roof membrane design pursuant to DIN 18195-5, Section 8.3.

The substructure must correspond to the superstructure build-up.
