Urbanscape Green Roll Substrate

Urbanscape Green Roll is a super lightweight green roof substrate made solely of virgin rock mineral wool fibres specially needled to form a compact and dimensionally stable felt. Urbanscape Green Roll ensures excellent water retention and conservation in green roofs and is a good growing medium removing the need for traditional soil substrates.

Description

Urbanscape Green Roll Substrate Key Benefits

  • 8 x lighter. Urbanscape Green Roll Substrate being a core of the Urbanscape Green Roof System is lighter compared to the traditional soil substrate and can be used on almost any building structure without compromising the structural stability. On average Urbanscape Green Roll is 8-10 times lighter and can hold up to 3-4 times more water per its volume than other green roof substrates.

  • 10x better water retention. Urbanscape Green Roll Substrate provides for fast and long-term stable water re-absorption and water retention performance. Depending on climate zones, different types of Urbanscape Green Roll are used.

  • Efficient installation (2-5 tonnes vs 100 tonnes). Urbanscape Green Roll Substrate ensures significantly lower labour intensity. For su.cient water absorption capacity and appropriate growing base for vegetation of 1000 m. of green roof, 2-5 tonnes of Urbanscape Green Roll Substrate are needed compared to above 100 tonnes of traditional green roof substrates.
