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.
