BRANZ is monitoring sun, rain, wind and wind-blown sea salt in different positions on a building envelope.
These conditions help to create a variety of micro-environments over the building that can be very different from the surrounding atmospheric environment.
This bulletin reports on the first monitoring of how micro-environments affect material performance on a BRANZ test building near Wellington.
This bulletin covers:
- Testing and the test building
- Time of wetness
- Wind-driven rain
- Salt deposition
- UVA irradiation
- Corrosion rates of mild steel coupons
- Corrosion rates of mild steel nails in timber
