The Past

Historically torch on membranes have been treated as 'alternative solutions' to compliance with E2. Often they have been a sticking point when proving compliance for building consent.

The Present

CodeMark certification is administered by the Ministry of Business Innovation and Employment (MBIE) and is the pinnacle certification for building products in New Zealand. Councils must accept a CodeMarked product provided it is designed and used within the scope of the CodeMark certificate.

Nuralite's reputation depends on us making sure our products and systems not only perform impeccably but that they fully comply with the New Zealand Building Code. We looked at obtaining CodeMark certification for the torch on Nuraply 3PM system because it would mean compliance was easily proved.

Question: Practically speaking, what does this mean for you, the designers and specifiers?

First, you look at the scope of the CodeMark Certificate.

Within the scope of the Nuraply 3PM Installation Manual you may:

• Have 1:40 (1.5o) falls on plywood substrates, supported by nogs and rafters at 600mm centres with 17mm ply for roofs, and 21mm ply for decks. This is a lower slope than E2/AS1 and saves money on framing timber and labour.
• Have 1:60 (1o) falls on a concrete substrate — a slope that is half the E2/AS1 roof slope. The slope may be formed with a screed or using Enertherm tapered PIR boards for a quick and lightweight system.

Specifiers may now have confidence that with double layer Nuraply 3PM, the waterproofing system they choose can easily gain Building Consent because it complies with the New Zealand Building Code.
