BU631 How micro-environments affect material performance
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.
