RAG quality mark

The quality mark RAG Green Roof guarantees a qualitative good green roof substrate. The nutrition in the green roof substrate is balanced, through which the plants take advantage of the optimal basis for a lifetime as long as possible.

The RAG Green Roof puts clear requirements to the green roof substrate. As a result you can trust that all delivered green roof substrates:

  • are clean (among others free from human pathogens) and lacking weeds
  • have an optimal oxygen content, through which the plants get the most favourable basis for a lifetime as long as possible
  • comply with the environmental standards (among others no heavy metals)
  • have an optimal buffering / water buffering capacity, that complies with the strict requirements of the independent control. The RAG green roof substrate combines water buffering with physical properties for an optimal growth.
  • restrict the pressure on the city sewer by dosed water drainage
  • have a warmth and noise isolating effect. As a result gas and heating costs can be saved and costs of the air conditioning can be decreased.

Only companies that have joined RHP can supply green roof substrates with the RAG quality mark.
