Out of sight but front of mind
The selection and maintenance of building elements and materials is one situation where out of sight should not be out of mind. In many situations, corrosion and deterioration may be occurring that is difficult to detect or see.
Atmospheric corrosion challenges
New Zealand’s unique environment, with its long coastline and geothermal areas, provides challenges for building material durability. To help, a BRANZ pilot study has made progress towards a unified atmospheric corrosivity map.
Plastics weathering
Sunlight causes plastic to degrade, but not all types are affected to the same extent. Research at BRANZ is investigating the lifetimes of a range of materials in different parts of the country.
Time tests PVC and polycarbonate sheets
Two long-running BRANZ studies are investigating the durability of rigid PVC wall claddings and polycarbonate sheeting products. How are these materials lasting, and what can we learn?
Zinc coatings on mild-steel fasteners
Avoiding corrosion of fasteners requires careful detailing to ensure detrimental chemical reactions do not occur, which can reduce the life of the fastener.
Sun-smart materials
Polymeric building materials can perform poorly under our very high solar radiation and uv levels. That makes it very important to confirm the building materials you are using have the appropriate uv stabilisers.
Choosing a nail or screw for 50-year durability
Selecting the correct nail or screw type for a particular situation is important but can be complex. This has just got easier with BRANZ’s decision tree for selecting nails and screws for use in timber.
Enhancing metal element durability
Metal building elements may deteriorate more quickly without regular washing, so what should designers consider when incorporating metal building elements in their designs and what maintenance advice should they give clients?
Database of durability
Durability information is currently in high demand. To address this, BRANZ is developing an interactive database of durability and compatibility information, designed with a range of users in mind.
