The sedum cassette system specially developed by WSM consisting of planted cassettes made of recycled HDPE. Each sedum cassette is pre-planted with up to 16 different sedum species. The plants grow on a specially developed substrate. Upon delivery, the sedum cassette is always covered with a minimum of 95%. Thanks to the integrated intelligent irrigation system, excess water can be dispensed, or water can be saved for drier periods. The support system of the roofing can easily support the additional load, of max. 280 KG realize. Like any roof, a green roof requires maintenance about twice a year. The WSM system is walkable and durable.
A well-rooted sedum canopy does not require additional water. The buttercups, also called sedum plants, are good at retaining water in their leaves and are therefore excellent in different weather conditions. Only under very dry conditions does the green roof need to be supplied with additional water.

GreenPlus Premium
- Especially bee and insect friendly
- Refined with selected flowering plants
- Variety ratio per trough precisely loaded
- High durability due to very mineral substrate
The Green+ Premium green roof offers a particularly natural plant community. In addition, the premium version is particularly bee and insect friendly. The addition of diverse flowering plants provides additional food and therefore habitat for bees and insects. To complement the carefully selected sedum plants, the green roof is enhanced with the following flowering plants:
- Common sage (Salvia officinalis)
- Soapwort (Saponaria ocymoides)
- Oregano (Origanum vulgare)
- Chives (Allium schoenoprasum)
- Catnip (Nepeta racemosa)
- Early flowering thyme (Thymus praecox)
Each individual vat is precisely loaded in the exact grade ratio. Flower colors, plant habit and flowering dates are specifically combined. This is immediately evident by a varied and valuable growth, which is still visible after many years.
The special manufacturing process allows the use of very mineral substrate. This high mineral content significantly increases the service life of the green roof. Drainage is improved and the risk of foreign growth is reduced.

WSM accompanies your green project from planning to transport. Upon delivery, you will receive the finished system complete with integrated green roof.
