Application

  • Suitable for use on inverted roofs to drain water away from insulation panels under accessible surfaces.
  • Can be used in extensively planted as well as in accessible inverted roofs covered with paving stones or slabs.

Description

Thanks to its breathable perforation and its dimples, water and air may circulate freely on the underside so that no coherent film of water can form on the insulation.


Features and benefits:

  • Offers high drainage capacity for green roofs.
  • Breathable and water-permeable due to the perforation between the storage dimples – ideal for inverted roofs.
  • Capable of storing 7 L/m² of water as a reserve for periods of drought.
  • Features the unusual compressive strength of 200 kN/m² thanks to its innovative octagonal dimples.
  • Can be laid easily and cost-efficiently at a rate of 40 m² per roll.
  • Forms an excellent foundation for green roofs together with DELTA®-BIOTOPVLIES.
  • Safe for drinking water and rot proof in soil.
  • CE-conformable as per BS EN 13252.
