With this certification, specifiers can now have confidence that the double-layer Nuraply 3PM, Nuraply 3PT/3PTM and Nuraply 3PG waterproofing system will readily gain Building Consent on substrates with falls as low as 1 degree.
What is CodeMark?
Previously torch-on membranes have been treated as 'alternative solutions' to demonstrate compliance with the Building Code. Often this has been a sticking point as Councils enforced different standards.
CodeMark certification is administered by the Ministry of Business Innovation and Employment (MBIE) and is the pinnacle certification for building products in New Zealand. By law, Councils must accept a CodeMark certified product provided it is designed and used within the scope of the CodeMark certificate.
Key Specification Points
Within the scope of our CodeMark certificate you may:
Lower Build Costs
Nuraply 3PM CodeMark can lower the cost of Flat Roofing in many ways:
|Cold Roof||Warm Roof (Nuratherm)|
|Substrate||Plywood||Concrete||Existing Substrates||Concrete with Tapered Boards or Flat Enertherm||Plywood with Enertherm||NPM900 or approved metal tray (B) with Enertherm|
|Design Fall (excluding gutters) (A)
||1:40||1:60||1:60 Confirm no ponding areas||1:60||1:40||1:40|
|Substrate Comments||Using 17mm (roofs) or 21mm (decks) plywood, rafters at 600 centers, nogs at 600 centers.||Create required slope with a screed. Wait for concrete and screed to cure.||Confirm substrate is sound||*Minimum fall available using tapered boards is 1:80. Nuralite to assist with tapered board layout
||Create required slope in the plywood||Create required slope in the NPM900|
|A)||For the purpose of this Certificate roofs must have a minimum finished fall of 1:80.
For design purposes, a minimum 1:40 finished fall should be assumed for plywood and metal substrates or 1:60 for concrete.
If lower falls are required Nuralite will issue a Producer Statement following detailed analysis of the roof including its size, location, overall and local deflection, direction of falls, etc.
|B)||Other metal tray systems may be used as a substrate with specific approval by Nuralite which is provided on a case by case basis.|
