GF WS rockwool

Hygroscopic rockwool in GF extensive green roof systems is used as a retention and drainage layer. It has excellent retention and water permeability constituting a water buffer. After reaching the maximum saturation, it discharges excess rainwater.

In the GF extensive green roof system, it is usually combined with sedum mats, and it is also successfully used in hybrid systems in combination with the GF MS mineral substrate.

It is also compatible with intensive green roof systems.
