PITCHED ROOF 15-45°

Greening pitched roofs with anti-slip system T (Carrier)

Pitched roofs, especially those with wooden roof constructions, often have only limited load reserves. Green roofs on these pitched roofs are therefore usually designed as thin-layer extensive green roofs.

The anti-slip system T is suitable for green roofs on all monopitch and pitched roofs up to a roof pitch of approx. 45° - as for our green roof system pitched roof 15-45°. It is very robust and can be easily walked on during installation. This makes it easier to install on steep surfaces with a roof pitch of over 40°.

Made from recycled plastic

The anti-slip system T is made of rot-resistant recycled plastic. The simple plug-in system consists of shear beams (3,250 mm long) and shear sleepers (107 mm long) with a height of 80 mm. The sleepers are inserted into each other at the required sleeper spacing depending on the roof pitch and construction height. Excess water is stored and drained away underneath the system using the Structured Storage Fleece SSV 800.
