Green Roofs
Knauf Insulation Urbanscape Build Up


Our mineral wool green roof growing mediums help to produce innovative extensive green roofs which support sedum, moss, herbs, grasses and other vegetation where low or no maintenance is required.

Key considerations when designing green roofs include overall weight of the system to ensure it can be supported by the roof structure, in addition to water retention capability of the system to minimise stormwater runoff.



  • Mineral wool substrates can be 8-10 times lighter than regular green roof substrates, meaning they can be installed onto lightweight constructions where traditional systems are otherwise not possible.

  • Mineral wool substrates can hold up to 3-4 times more water per its volume than other green roof substrates, allowing lower capacity drainage systems to be used.
