Fire Stopping Requirements NZ
Fire stopping requirements in New Zealand are tied to the need to maintain the fire performance of rated walls, floors and other fire separations when they are penetrated by building services.
BAKKER PFI shares practical guidance to help building owners, managers and project teams understand passive fire work more clearly.
Article overview
Fire stopping is required where services pass through fire-rated elements and where those elements need to maintain their intended fire resistance. In practice, this means openings created for pipes, cables, cable trays and similar services need suitable tested treatment.
What fire stopping is
Fire stopping is the treatment of openings, penetrations or joints in fire-rated elements so those elements can continue to perform as intended in a fire.
Where fire stopping is required
Fire stopping is commonly required in fire-rated walls, floors, risers, shafts, plant areas, service cupboards and other parts of buildings where penetrations pass through fire separations.
Why tested systems matter
A compliant solution should be based on a tested system suitable for the service type, substrate, opening size and required fire resistance outcome.
Common defects
Common defects include missing fire stopping, oversized openings, unsuitable products, incorrect collars, poorly installed sealants and damaged systems left after service changes.
