This study is the second part of the research project that aims to check and maintain the ongoing validity New Zealand atmospheric corrosion rate dataset. This dataset underpins the New...
Atmospheric corrosion testing was conducted at 39 exposure sites across New Zealand. The corrosion rates of mild steel and hot-dip galvanised zinc-coated coupons were measured after 1 year of exposure...
The findings from inspections of several houses to date confirm that although serious problems with urea formaldehyde foam insulation (UFFI) installation process within New Zealand appear relatively rare, there are...
This report provides the findings on the overall condition of New Zealand houses. The analysis uses the data collected from the fourth House Condition Survey Study (2010). This survey is...
This report compares the condition of rental and owner-occupied houses surveyed in the 2010 BRANZ House Condition Survey.Approximately 500 stand-alone, townhouse or terraced houses/units were inspected throughout New Zealand, and...
BRANZ has developed a two-stage accelerated test methodology to determine the aggressivity of timber treated with different preservation chemicals towards mild steel and ho- dip galvanised nails.In comparison with conventional...
This is the Appendix to SR241. The full report summarises the results obtained from the third year of field exposure tests carried out at BRANZ’s Judgeford site.It discusses the corrosion...
This report summarises the results obtained from the third year of field exposure tests carried out at BRANZ’s Judgeford site.It discusses the corrosion performance of typical metallic fasteners embedded into...
Work to evaluate the properties of urea formaldehyde foam insulation (UFFI) and the effect UFFI has on the moisture management processes within brick veneer construction has been completed. This work...
Most of the commercial organic-based polymers used in the building and construction industry undergo photolytic and photo-oxidative reactions during exposure to solar UV radiation.The premature failure of these building polymers...
