Description

BRANZ researchers have been analysing how much fire resistance is needed for external walls in industrial buildings. Results show the Building Code minimum fire-resistance ratings could be reduced for some.

External walls close to property boundaries are commonly fire-rated to help prevent fire spread to a neighbouring property as required by New Zealand Building Code objectives.
