Floraxx TOP is a water-retaining drainage sheet designed for use on inverted, green and paved roofs. It has breathable perforations and dimples that allow water and air to circulate freely on the underside, preventing a coherent film of water forming on the insulation.

Features, benefits and applications

  • Offers high drainage capacity for green roofs

  • Is breathable and water-permeable

  • Features the outstanding compressive strength of 200 kN/m² and an enlarged water retention capacity thanks to its innovative 20-mm high octagonal dimples

  • Eliminates an entire laying operation because of its integrated geotextile, on which substrate can be spread immediately after the sheet has been rolled out

  • Forms a consistent homogenous surface without the problems caused by loose cloth layers slipping, shifting, or being blown about by the wind

  • Is capable of retaining 7 l/m² of water as a reserve for periods of draught

  • May also be used on green inverted roofs because it is breathable (S value: c.0.4 m)

  • Is CE conformable as per DIN EN 13252 and meets the requirements of the FLL guideline for green roofs

  • May be easily and safely joined with the enclosed Delta Florexx connecting elements
