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
