Drainage system ND 5+1 (25 m²) in the package

Drainage system for flat roofs.

A high-performance drainage system made from recycled high-strength "tough" polystyrene (HIPS), with an innovative stud design and CE marking. 

The core of the ND 5+1 drainage system is a perforated vapor-permeable nop foil with a water retention of approx. 5.8 l/m². The core is characterized by high compressive strength with a profile height of approx. 27.5 mm. 

The black non-woven filter geotextile is glued to the surface of the smooth side of the perforated core, and the white non-woven geotextile, performing the functions of vapor permeability, protection and separation, is connected to each stud on the reverse side of the film.

The ND 5+1 drainage system is part of the AGRO CS Extensive and Intensive Green Roof Systems. In these formations, they perform the function of filtering, drainage and protective layers. The ND 51 drainage system is suitable for installation in green roofs with insufficient structural clearance. The structural height of around 28 mm prevents the substrate from getting too wet and the risks associated with the pavement freezing. This profile height also allows for greater distances needed to drain the area. It is suitable for a "classic" warm roof construction composition as well as for an inverted roof construction composition.
