This pitched roof greenery system can also easily be applied to the existing roof architecture during renovations or refurbishment work (it is essential that the static engineering conditions are kept to). This environmentally conscious alternative for conventional tiled roofs is impressive, with an excellent price-performance ratio and an installation system familiar to every roofing contractor. The particularly high anti-slip and shear resistance of the GDP 45 ensures greater safety and longevity of the green roof.

From pitched roofs with angles of inclination in excess of 15°, we recommend use of pre-cultivated sedum mats. Sedum matting is installed when no frost is present and are at least 95 % green on delivery. They consist of six to eight different sedum species that are particularly suitable for extensive planting. The minimum maintenance requirement is limited to one to three service or maintenance cycles per year, depending on build-up and location.

TOPGREEN sedum shoots

Freshly cut shoots of the individual sedum species can take root in the substrate within a few weeks, and develop into fully grown sedum plants. After spreading, the sedum shoots must regularly be supplied with moisture during the first 4-6 weeks. TOPGREEN sedum shoots are ideally suited to extensive flat roof greenery with a roof pitch of up to 15°.
