GXP® DREN 20 P

Water reservoir for roofs and terraces

GXP® Dren 20 P is a combination of a perforated bucket membrane with geotextile DuPontTM TYPAR®, which constitutes an ideal drainage layer on extensive green roofs, at the same time serving as a filter, a water accumulating tank and a dehydration layer. A durable joint of the perforated bucket membrane with the thermowelded geotextile ensures high easiness during installation at sites as well as accelerates the works.

Advantages

  • Ensures water accumulation for plants (intensive vegetation)
  • Very resistant to compression and breakdowns
  • High densification of embossings 400 items/m²
  • Increased thermal insulation
  • Limited heat accumulation
  • Optimal dehydration capacity
  • Certified material compliant with norm PN – EN 13252
