gtSedum Green Roof Cassettes


Designed specifically for extensive green roof installations, gtSedum Cassettes can convert a roof into a lush sedum green roof simply and effectively.


Incorporating a minimum of 8 types of sedum into each individual cassette, the system is designed to provide an instant and practical solution to green roofs.

Sedum is the ideal choice for extensive green roofs, as it requires minimal maintenance, is drought tolerant and requires a minimal substrate layer. It is a well-rooted, low-growing plant therefore it is ideal for the harsh, open environments typically associated with green roofs.   Green roofs are quickly becoming a great resource for urban greening and conversions of large open roof spaces, with the evolution of sedum cassettes green roofs are achievable for all.


The installation process is straightforward, the cassettes are designed to simply fit together to any formation required. Each cassette incorporates a drainage layer to aid capillary action and a filter layer to ensure that the lightweight substrate is not washed away. The lightweight substrate has been specifically developed for use in green roof installations with controlled levels of fertility to support sedum growth.


Please order in square metres. 4 cassettes per square metre.
