Fire Shield TimberClear – Fire Retardent Coatings

Fireshield Intumescent FR coatings save lives & property

Fireshield TimberClearNCC Compliant Group 1 Clear Coatings

With the heightened focus on fire safety, timber interiors have been subjected to increased scrutiny and some limitations and restrictions may apply to its use (see table at bottom). Some designers wishing to incorporate timber in their projects initially struggled to meet the requirements of the NCC 2019 without limiting the design creativity, particularly in public spaces. Fireshield clear coatings now enable far greater design freedom for timber interiors enabling you to achieve Group 1 fire rating whilst showcasing timber with extraordinary effect.

Fireshield test showing the coatings resistance to fire and intumescent qualities compared to untreated timbers. When direct flame is applied to the coating it forms a charred skin which retards flame.

Fireshield is a clear intumescent coating system that expands and chars when exposed to flame, creating a non combustible protective layer over the substrate. Provided the timber is 12mm thick it complies with the requirements of Group 1 rating making it possible to use almost any timber in decorative applications.

Fire sensitive areas such as lift wells, corridors and fire exits which were previously excluded can now be lined with timber . Timber stains can be applied under the coating enabling you to match the other decor features.

Maintenance is also minimal for the life of the building and any physical damage can be repaired in situ.

The coating does require a high level of expertise to apply properly and is best applied under controlled conditions rather than on site for best results making pre coating the preferred option. It should only be applied by accredited applicators appointed by Dulux.

As accredited Fireshield specialists we are a leading applicator on items such as lining boards, battens and panels. Full compliance certification is issued for each project.

SOME TIPS

Certification

Always use a certified applicator and request the certification documentation for each job. Factory pre-finishing will almost always provide a better finish and compliance than on site application, and will not disrupt site operations. The coating needs to be applied at specific thicknesses to be compliant.

Lead Times

Always contact your applicator to determine lead times for the coating when planning your project – unlike most coatings Fireshield may take up to 10 days to dry sufficiently for transport and handling.

Colour Matching

Fireshield is slightly translucent which becomes more obvious on dark solid colours. This may not be noticeable if the complete job is coated with Fireshield, but typically it is used in conjunction with other coatings on a project to reduce cost.

In these instances it is essential the coatings are matched for gloss level and appearance and this is best achieved by getting both coatings done simultaneously so the applicator can match them.

Handling on site:

Fireshield is touch dry in 7-10 days but does not harden completely for 30 days – handling instructions are provided to the installer and it is important they adhere to these to prevent marking of the coating on installation. It is good advice to familiarise yourself with these prior to arrival and unpacking of shipments

Solid Colours

Although the clear coating is most popular on interior timbers, often solid colours are required – in this case the timber substrate is pre-coated with the Fireshield and the final top coats, which can be most interior paints, are applied over the Fireshield undercoat allowing the designer access to an almost unlimited colour palette.

COMPLIANCE TO THE NCC

The NCC is a performance based code permitting the use of innovative materials, components or construction methods.

To achieve compliance with fire hazard properties for internal wall
and ceiling linings, a Performance Solution or a DTS Solution needs
to satisfy the Performance Requirement CP4 – Safe conditions for
evacuation.

The Performance Requirements are supported by General
Requirements, which cover general rules and instructions for using
the NCC including:
• its interpretation,
• reference documents,
• acceptance of design and
• construction and the classification of buildings.
The General Requirements also contain guidance on how a building
product or a material can satisfy the Performance Requirements.
Diagram 1 illustrates the available pathways to compliance and what
is required along each pathway.
Deemed-to-Satisfy (DTS) Solution
A DTS Solution is the one most commonly used pathway and follows
a set recipe of what, when and how to do something to demonstrate
compliance with the NCC. A solution that complies with the DTS
provisions is automatically deemed to have met the Performance
Requirements and achieves compliance with the NCC.

Hence the term “Deemed-to-Satisfy”.
A DTS Solution can show compliance with the DTS Provisions
through one or more of the following Assessment Methods:
• Evidence of Suitability in accordance with Part A5 of NCC 2019
• Expert Judgement.
These DTS provisions are for all solutions and building materials
involved in the construction of buildings in Australia, including fire
hazard properties.
The Governing Requirements for a building component or assembly
to have a fire hazard property are described in Part A5.5 – Fire
hazard properties. It references Specification C1.10, which specifies
limitations on the use of these materials, depending on the type and
class of buildings and the corresponding fire suppression systems.
Performance Solution
The second pathway to compliance is the Performance Solution,
which is a method of complying with the intended Performance
Requirements other than the previously mentioned DTS Solution.
The Performance solution is achieved by demonstrating compliance
with all relevant Performance Requirements or a solution that
is at least equivalent to the DTS Provisions. All Performance
Solutions must be shown to comply with the relevant Performance
Requirement using one or a combination of the following
Assessment Methods:
• Evidence of Suitability
• Verification Method
• Expert Judgement
• Comparison with Deemed-to-Satisfy Provisions.
Refer to the National Construction Code (NCC 2019) for details on
each of the Assessment Methods.

All Assessment Methods and corresponding supporting evidence
used to determine this outcome and achieve compliance with
Performance Requirement CP4 are in Appendix B of the CodeMark
Certificate.
The NCC 2019 recognizes a current CodeMark Certificate of
Conformity as a valid Evidence of suitability document to show
compliance with a Performance Requirement, as per Clause A5.2 1(a)
of Part A5 – ‘Documentation of Design and Construction’ in NCC 2019
Volume One.
The CodeMark Certificate must be accepted as proof of compliance.

EXAMPLE CODEMARK CERTIFICATE OF CONFORMITY

Summary
• Fireshield® timber intumescent coating systems achieve
compliance with Performance Requirement CP4 of NCC 2019
and offer a Group 1 rating to interior timber wall and ceiling
linings.
• All Fireshield® timber intumescent systems can only be used as
part of a Performance Solution.
• Compliance to the Performance Requirement CP4 is shown in
the form of a CodeMark Certificate of Conformity.
• All Fireshield® timber intumescent systems are certified to a
Group 1 rating for interior timber substrates >8 mm thickness
and >338 kg/m³ density.
