Ventilation of cold roof designs in New Zealand doesn’t always go smoothly. Here, BRANZ physicists hand over to a couple of professional builders who have long been at the coalface dealing with roof moisture issues on their projects.
The second in a series looking at how current New Zealand building regulations for energy efficiency compare to those elsewhere measures New Zealand against Australia.
This is the first in a series looking at how New Zealand building regulations currently compare to those elsewhere.
This is the second article in Build’s new section on MBIE determinations. It looks at lessons from Determination 2019/057: Regarding the issue of a notice to fix for building work carried out without a building consent and over a property boundary.
To simplify the consenting process for structural insulated panels (SIPs), we need to know how they perform locally. A BRANZ research project is helping by examining SIP durability, earthquake and fire performance.
Proper on-site management of roof cladding is critical to delivering quality buildings. This is the final in a series on materials storage requirements and outlines how to store and handle roof claddings.
The risk matrix in E2/AS1 is a key tool for weathertightness assessment and showing compliance with the Building Code. Let’s walk through the steps on how to use it.
BRANZ regularly receives queries about hold-down fixings to the exterior walls of timber-framed buildings. This overview sets out the fixing requirements in NZS 3604:2011 for resistance to uplift for the various framing members.
The third in this series looking at how current New Zealand building regulations for energy efficiency compare to those elsewhere measures us against Ireland.
