Advantages of GreenPlus

For you, the environment and the people

Air purification

Green roofs bind particulate matter and carbon dioxide (CO2) and break down carbon monoxide, hydrocarbons and benzene from diesel and gasoline exhaust.

Maintenance of biodiversity

Sedum plants provide new habitat and food for bees, butterflies, beetles, ants and birds.

Insulating effect

The green roof acts as a biological heat shield in summer and a heat accumulator in winter.

Protection of the roof cladding

The foliage absorbs the solar radiation and thus protects the roof surface or increases its service life.

Precipitation water storage

Unsealing gray areas naturally retains stormwater, relieving pressure on the sewer system and minimizing the risk of flooding.

Noise reduction

Substrate and plants increase sound insulation because they do not reflect sound. The road noise and also the railroad or airplane noise are naturally absorbed.

High efficiency

Green+ pays off for you because the acquisition costs for the basic construction with higher roof load (70 kg/sqm additional weight) are comparatively very favorable.

A plus for people and nature

The system is composed of modules that can be easily and safely integrated into the trapezoidal profile of our roofs. The modules consist of special tubs, which are equipped with resistant sedum plants. We supply products equipped with GreenPlus as a complete solution. You can be sure that all constructions meet the highest static requirements.

GreenPlus Economy

  • Planted cassettes from recycled HDPE
  • Sedum cassette always covered with a minimum of 95%.
  • Preplanted with up to 16 different sedum species
  • Plants tolerate even very dry conditions

Everything from a single source: Thanks to the patented Green+ Economy green roof system, roofs receive many added values at once. Your advantage: The greening is already carried out in the factory - there is no need to call in an external specialist company again. Thanks to an ecological and environmentally friendly packaging made of jute, your Shelter system with Green+ Economy planting will arrive at your door safely and just in time.

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.

Completely from one source, completely green

WSM accompanies your green project from planning to transport. Upon delivery, you will receive the finished system complete with integrated green roof. The roof is already 95 percent covered with the plants for your direct use. And to make sure your project is environmentally sustainable all around, our planting modules are made of recyclable HDPE material and our transport protection is reusable.


The plants: naturally from the expert

We leave nothing to chance and rely on the great experience and safety of our partner companies for the cultivation of sedum plants.

The plants pre-cultivated on special substrate (up to 20 different species) are particularly robust, hardy and suitable for a wide range of weather conditions. With just a little water and annual maintenance, your green roof will remain a true statement of environmentally conscious architecture - for generations to come.
