Tips to improve durability
Plus: Who's building New Zealand?
A new BRANZ project aims to help improve the durability of timber structures by deepening understanding of the part moisture dynamics plays within timber.
BRANZ has been investigating what can make metal fasteners and fixings corrode when used in timber. Understanding this can lead to selection of compatible components and less risk of premature failures.
A clever piece of technology at BRANZ enables scientists to verify that building products are indeed made of the materials they claim to be.
The guidance for using structural steel and other metals in Building Code clause B2 Durability is limited, and no Acceptable Solutions are offered. Perhaps there’s a need for an addendum to be incorporated.
BRANZ and the University of Auckland are conducting research into the durability of one-component polyurethane adhesives for laminated structural timber elements.
Even if it is treated, timber can sometimes decay sooner than expected. When this is because of an active fungal population in the surrounding area, simple actions can prevent replacement timber from also rotting.
