Introduction

Nuraply 3PG is Nuralite’s go-to solution for green roofs, built to handle the unique demands of vegetated systems. Its reinforced, herbicide-impregnated finish offers robust root resistance, making it perfect for all types of landscapes on rooftops. 


With a long history of use across city buildings, green space initiatives and unique properties, Nuraply 3PG has proven its reliability in New Zealand’s diverse climate. 


Typically installed on as part of a full green roof build-up—including drainage, filtration, and planting layers. When paired with products like Nuramat Greendrain, it creates a high-performing system that delivers both waterproofing and stormwater retention benefits. 


While detailing is critical, especially around upstands and junctions, the membrane is straightforward to install by approved contractors. For specifiers seeking a green roof system with CodeMark certification, Nuraply 3PG offers a tested, dependable system.

Considerations

  • Not suitable without a drainage layer: Nuraply 3PG must be used in conjunction with a proper drainage and filter layer to manage water flow and prevent saturation.


  • With a mineral chip coating, it may be exposed to UV on upstands or parapets. It is recommended to use 3PG under Ballast roof systems in case weeds germinate or if the roof system is later changed to a green roof.


  • Green roofs are not suitable for the collection of potable water - especially as they soak up 80% of the water during downpours


  • Is suitable for use as a tanking membrane where plants may be planted adjacent to the wall system.


  • Pay attention to the type of plants which are located near the membrane. Additional protection will be required if the plant has invasive root systems. Examples are Bamboo, Pōhutukawa trees and even Paspalum grasses.

FAQs

What layers go into a green roof system using Nuraply 3PG?
A typical green roof system using Nuraply 3PG includes, in order, a concrete or primed substrate, a basesheet waterproofing layer, the Nuraply 3PG membrane with its root-resistant finish, a polyethene protection sheet, a drainage layer (for example, Nuramat Greendrain), a filter fabric, followed by the growing medium and vegetation. This multi-layer assembly ensures effective waterproofing, proper drainage, and long-term protection for a thriving green roof.
Can Nuraply 3PG be used with insulation?
Yes, Nuraply 3PG is compatible with both Nuratherm PIR and Nuratherm XPS insulation systems. When paired with high-performance insulation such as PIR or XPS, it forms part of a warm roof assembly that maintains continuous insulation, minimizes cold bridging, and effectively manages moisture. This integration supports overall energy efficiency and reliable waterproofing performance.
Is Nuraply 3PG suitable for semi-intensive green roofs?
Absolutely. Nuraply 3PG is specifically engineered for semi-intensive green roofs where a deeper growing medium and diverse plantings are used. Its reinforced, root-resistant design offers superior protection against plant penetration and mechanical stress under the heavier loads typical of semi-intensive systems.
