Application

Suitable for pitched roofs.

Description

Sloped green roofs require special attention right from the initial planning phase. Roof pitch, roof design, roof structures, loading and the required shear resistance measures all need to be adjusted for the desired vegetation. If the roof has a pitch of 10° or more, anti-slip systems are generally used. For pitches of 15° or more, the use of vegetation mats is recommended. Depending on the structural constraints, there are various anti-slip systems to choose from.


Features and benefits:

  • Together with the Extensive Substrate E, the Optigrün shear protection systems for the greening of pitched roofs form a stable and easily rootable layer for the vegetation.
  • The pre-cultivated vegetation mats serve as surface erosion protection and allow the vegetation to establish quickly.
  •  Sustainable solutions for greening sloped and steeply pitched roofs.
