PITCHED ROOF 10-30°
Greening pitched roofs with anti-slip system P (Board)
Due to the often limited load reserves on pitched roofs, especially on wooden roof constructions, most green roofs are designed as thin-layer extensive green roofs. This is also the case with our PITCHED ROOF 10-30°.
The anti-slip system P is suitable for pitched and gabled roofs up to a roof pitch of approx. 30°. The advantages of the system lie in its quick installation, easy cutting to size and low price. Solid and inexpensive pitched roof greening up to 30° can be realized. For roof pitches from approx. 25°, the use of the vegetation mat fixing strip is required to secure the vegetation mats in the area against slipping.
