The basics

What is service penetration fire stopping?

Every time a pipe, cable, duct or conduit passes through a fire-rated wall or floor, it creates a service penetration, a breach in the building's fire and smoke separation. Left unsealed, that breach lets fire and smoke pass straight through, defeating the compartmentation the building relies on.

Service penetration fire stopping reinstates the fire resistance of that wall or floor using tested systems installed exactly to the manufacturer's specification. It's a requirement of the NZ Building Code (Clause C/AS), and it's checked by your IQP, council and BWOF, which is why every seal we install is documented and tagged.

Fire compartmentation maintained by sealed service penetrations
What we seal

Every penetration through a fire-rated wall or floor

Whatever the service, substrate or fire rating, we have a tested system to seal it, in new builds and existing buildings.

Plastic & metal pipes

PVC, HDPE, copper and steel pipes sealed with fire collars, wraps and sealants matched to pipe type and rating.

Electrical cables & trays

Single cables, bundles and loaded cable trays through walls and risers, sealed to maintain the rating.

Conduits & sprinkler pipes

Electrical conduits and fire sprinkler pipework, sealed without compromising the service.

Insulated services

Insulated and lagged pipes sealed with systems tested to keep the insulation continuous and compliant.

Mixed & combined services

Tight, congested penetrations with multiple services, sealed with batt-and-seal or mortar systems.

Cast-in & retrofit

Cast-in devices for new pours and retrofit systems for existing penetrations and remedial work.

Tested systems

The fire stopping systems we install

We don't guess. We select tested, BRANZ-appraised systems matched to the service, substrate and required fire rating.

Intumescent fire collars

Wrap-around and cast-in collars that crush plastic pipes closed under heat to maintain the fire seal.

Intumescent pipe wraps

Flexible wraps for combustible pipes where a collar won't fit, expanding to seal the opening.

Fire-rated sealants

Acrylic and silicone fire sealants for smaller penetrations, gaps and cable seals.

Fire pillows & bags

Re-enterable pillow systems for cable trays and risers where services change over time.

Fire-rated mortar & coated batt

Mortar and coated batt systems for large or congested mixed-service penetrations.

Fire boards

Board systems to reinstate openings and form fire-rated penetration seals in walls and floors.

Our work

Real penetration fire stopping, tagged & documented

Every seal we install is tested, tagged and recorded, verifiable for your IQP, council and auditors.

Compliance & documentation

Fire stopping you can prove

A fire seal is only as good as the evidence behind it. As a PS3 author, we hand over the records your IQP needs to certify the work and sign it off.

  • PS3 producer statements for the installed systems
  • Tagged penetrations recording the system, fire rating and location
  • BRANZ-appraised, tested systems installed to specification
  • Before & after photos, data sheets and as-built records
Our process

How we fire stop your penetrations

1

Assess & identify

We identify every penetration from drawings or on site and check it against the required fire rating.

2

Specify the system

We select the correct tested system for each service, substrate and rating with no generic assumptions.

3

Install

Installed by qualified passive fire technicians, exactly to the manufacturer's tested detail.

4

Tag & document

Every seal tagged, photographed and recorded, handed over with your PS3 and compliance pack.

FAQs

Service penetration fire stopping, common questions

What is a service penetration, and why does it need fire stopping?
A service penetration is any point where a pipe, cable, duct or conduit passes through a fire-rated wall or floor. It breaks the fire and smoke separation, so it has to be sealed with a tested fire stopping system that restores the wall or floor's fire resistance rating and keeps the building compartmentalised.
Do penetrations through a fire-rated wall or floor legally need fire stopping in NZ?
Yes. Under the NZ Building Code, a penetration through a fire separation must maintain that element's fire resistance rating. It's inspected by your IQP and council, and unsealed or non-compliant penetrations can hold up your Form 12A and Building Warrant of Fitness (BWOF).
Who is responsible for fire stopping service penetrations?
On most projects the main contractor carries overall responsibility for ensuring penetrations are fire stopped, while the trade that creates a penetration is responsible for it being sealed correctly. Whoever installs the seal carries the liability if it isn't installed exactly as tested, so it's best handled by a passive fire specialist using tested systems. We make that scope and responsibility clear from the outset.
What's the difference between active and passive fire protection?
Active fire protection (sprinklers, alarms and extinguishers) detects and fights a fire. Passive fire protection, including service penetration fire stopping, is built into the structure to contain fire and smoke and slow its spread, buying time to evacuate. The two systems work together.
What is a fire collar, and what does intumescent mean?
A fire collar is a device fitted around a combustible pipe such as PVC. Intumescent means it expands when heated. In a fire the collar swells and crushes the pipe closed, sealing the opening. We select collars, wraps, sealants, pillows or mortar based on the service, substrate and required fire rating.
Does my fire stopping need a PS3, and how does it affect my Form 12A and BWOF?
Your IQP needs evidence the passive fire systems were installed correctly before they can certify them. As a PS3 author, we provide producer statements, tagged records and photos for the systems we install. That's the documentation your IQP relies on to issue your Form 12A and keep your BWOF valid.
How much does service penetration fire stopping cost?
It depends on the number and type of penetrations, the services involved, site access, and whether it's a new build (priced off drawings) or remedial work in an existing building. We price the full scope accurately up front so there are no surprise variations. Send us your drawings or a description of the building and we'll give you a clear quote.
Do you work on new builds and existing buildings, and what areas do you cover?
Both. We price full penetration fire stopping packages for new builds and carry out remedial sealing in existing or occupied buildings. We cover Auckland, Northland and North Waikato.

Need penetrations fire stopped?
