Extensive substrate

SubLight ITG-02 is a lightweight substrate designed for extensive green roofs, creating optimal conditions for sedum vegetation while minimizing structural load. It balances drainage and water retention to support healthy plant growth and efficient roof performance.

Suitable for roofs with slopes up to 45°, including flat, single-pitch, gable, and multi-pitch roofs on residential, public, and industrial buildings, the substrate ensures plants receive essential nutrients even with a shallow soil layer.

The substrate is produced in accordance with FLL guidelines, the widely recognized German standard for the design, installation, and maintenance of extensive green roof systems.
