Nophadrain BV products

This high-quality plastic film prevents XPS insulation in an inverted roof / ND Drainage System from sticking to the waterproofing membrane. The film is applied in two layers, creating a separation and slip layer. The film is laid loosely on the roofing with an overlap of at least 100 mm.

Sustainable, stable hydrophilic mineral wool panels that naturally retain water for intensive green roofs. These panels make it possible to use topsoil instead of ND DGS-I Substrate Intensive as a planting medium.

This substrate is specially designed for extensive green roofs. The composition of the substrate is tailored to the needs of extensive vegetation and meets the requirements of the FLL Green Roof Guidelines for the design, installation and maintenance of extensive green roofs.

Inspection chamber with an insulated cap made of galvanised steel, for monitoring the working of the ND Drainage System on extensive green roofs. The inspection chamber is equipped with apertures for the ND Strip 150 Drainage System for use as a linear drainage system for single-layer extensive green roofs.

The plastic ND RS-30 / ND RS-50 Inspection Chamber, which has a sealable cap, is installed inside vegetation areas on the roof drain to monitor the drainage layer in an intensive green roof construction.

High-quality, CE-marked drainage system for extensive roof vegetation on medium pitched roofs. The ND Drainage System prevents the build-up of hydrostatic pressure on the waterproofing membrane and protects it against mechanical loads. The ND 120 Drainage System with a pressure-distributing protective sheet was specially developed for the Nophadrain "Clic" Sub-Structure Drainage and Protection System.

High-quality, CE-marked drainage system for podium decks with sufficient fall. The ND Drainage System prevents the build-up of hydrostatic pressure on the waterproofing membrane and protects it against mechanical loads.

High-quality, CE-marked drainage system with a perforated core for podium decks on an inverted roof. The drainage system prevents the build-up of hydrostatic pressure on the waterproofing membrane. The vapour-permeable geotextile on the back protects the XPS insulation from mechanical loads and ensures that vapour is able to evaporate freely from the XPS insulation.
