Nophadrain Intensive Green Roof System

Features and advantages of intensive green roofs

What is an intensive green roof?
Intensive green roofs are comparable to soil-bound green areas, such as gardens and park landscapes. The vegetation for this roof needs a lot of water and regular maintenance. The vegetation consists of lawns, shrubs, and trees and can easily be combined with pedestrian and vehicular pavements. Intensive green roofs are not only found on buildings, but also over underground constructions such as car parks. The space taken up by the buildings and underground constructions is indirectly returned by installing an intensive green roof.

Advantages of an intensive green roof

  • Optimal use of space: both the quality and quantity of the living environment is increased by making use of stacked space, particularly in urban areas.

  • Reduction precipitations in sewer system loads: the green roof system slows down rainwater runoff during peak loads that occur at times of increasingly frequent downpours.

  • Combatting the heat island effect: unlike concrete roofs, green roofs do not fully convert solar energy into heat, but into steam instead. This has a cooling effect on the surrounding area.

  • Protection of the waterproofing membrane: the vegetation helps to counteract the harmful effect of sunlight and rain on the waterproofing membrane. This protects the waterproofing membrane and it increases its lifespan.

The heart of the Nophadrain Intensive Green Roof System
The core of the Nophadrain Intensive Green Roof System is the ND 4+1h Drainage System. This multifunctional, CE-marked drainage system with high compressive strength protects the roof covering from water stagnation while at the same time, in combination with the WSM-50 Water Reservoir Panels, storing water (44 l/m²) for dry periods. In addition, the ND 4+1h Drainage System in combination with the ND TSF-100 Slip and Protection Sheet protects the waterproofing membrane against mechanical loads.


We would be glad to advise you about the options. We can help you maximize the advantages of green roofs while limiting the risks to a minimum.

Het hart van het Nophadrain Instensief Groendaksysteem

Het hart van het systeem is het CE-gemarkeerd ND Drainagesysteem (volgens NEN EN 13252) met een duurzaamheid van minimaal 25 jaar. Het Drainagesysteem is eenvoudig en snel aan te leggen doordat het op rol wordt geleverd en meerdere functies in één product zijn verwerkt. Het voornaamste voordeel is de hoge druksterkte waarover het ND Drainagesysteem voor intensieve daken beschikt. Bovendien is het systeem uitgerust met een geïntegreerd waterreservoir, dat de beplanting van water voorziet, maar daarnaast ook helpt om de riolen minder te belasten bij hevige regenbuien. Het systeem houdt water vast voor de vegetatie, maar zorgt er tegelijkerrijd voor dat het water niet opstuwd op het dak.

Wij adviseren u graag over de mogelijkheden. Zo helpen we u om de voordelen van groendaken optimaal te benutten en de risico’s tot een minimum te beperken.
