Choosing a fire rated coating for the correct substrate, environment and aesthetic can at times be a daunting task for even the most experienced Architect / Specifier.

That’s where we can help, we have Specifiers, an Architectural Designer and a Fire Engineer on staff that recognize exactly what you want when specifying an intumescent system. Fireshield is not your ordinary intumescent coating company, we are a bespoke company that can design and test systems specifically for your project as we did with our steel cladding test.

Fireshield offers fire protection that you can trust will provide the compliance you need, simple to install system installed by Registered Applicators and come with the warranties and technical back up required from the design phase to completion on site.

For technical or specification assistance contact our Technical Director, Blair Rouse on ph: (03) 925 8565 (NZ) or ph:1800 092 097 (AUS)

This page offers everything you need for your project from the design phase through to completion on site.

 

Timber Substrates:

The Fireshield range of timber intumescent coating systems are specifically designed to provide a group surface rating to timber substrates for Building Code compliance in commercial, multi-use, civic projects and many more depending on the Building Code classification.

What is a group surface rating? A group surface rating is a rating given to a substrate or finish in an internal space or fire cell, 1 being the highest and 3 the lowest. The group surface rating is required to increase life safety by preventing rapid fire growth in the early stages of a fire.

They are entirely separate from the requirements for fire resistance (based on charring rates) which are needed for containment and prevention of structural collapse in a fully developed fire. If you have a project that requires a structural fire rating to structural timber, give us a call as these require specific design.

Fireshield has three coatings available for internal timber substrates, all three provide a group surface rating up to the maximum required in New Zealand and Australia:

  • Group 1-S in New Zealand
  • Group 1 in Australia.

The three products available are TimberClear, TimberWhite and Timber Whitewash, see the Products Page for a description of each.

Before specifying a Fireshield timber intumescent system there are three prerequisites that must be met in order to be able to achieve a Group 1-S/Group 1 surface rating and all relate to the substrate itself:

  • It must be a timber-based substrate: it can be solid or made up of lamellas like plywood or made from wood products like strand board or MDF board. It cannot be a fake timber substrate or plastic laminate.
  • The timber-based substrate must be >8mm thick: for example, tongue and groove boards and panels need to be checked to ensure the groove is greater than 8mm.
  • The timber-based substrate must have a density > 338 kg/m³ : This density measurement is available on most timber TDS’, just give us a call if you are unsure and we will be able to help. As an example pine has a density or around 400 to 450 kg/m³ and hardwoods start at around 600 kg/m³ through to 1100kg/m³.
  • The Fireshield range of timber intumescent systems are for indoor use only, they cannot be used on the exterior of the building envelope, this includes timber soffits.

There are design considerations to bear in mind when specifying internal timber linings, this applies to all coatings not only intumescents:

  • Have you specified the coating in the correct interior environment, see the product TDS for details.
  • The timber substrate is detailed to prevent any possible future damage to the timber and the coating, for example finishing the timber short of an adjoining hard floor with the use of negative skirtings.
  • Check the building Code for exemptions, items that do not need to be coated such as window jambs and door frames.
  • Now it’s just a matter of deciding what finish you would like, clear natural finish in a matt or semi-gloss, a pigmented finish using any colour you want or a whitewash finish perfect for light timbers such as pine.

 

Steel Substrates:

Fireshield has water-based and solvent-based intumescent steel products for 30, 60, 90- and 120-minutes protection. Steel coatings are firstly divided into:

  • Interior use
  • Exterior use

From there you need to choose a corrosion zone, these come from BS EN ISO 12944-2. The corrosion zones are available online and are categorized as C1 through to C5/CX interior and Exterior.  For example C1 Interior is for heated buildings with clean atmospheres, e.g. offices, shops, schools, hotels and C5 interior are buildings or areas with almost permanent condensation and high pollution.

The three products available are Steel 1001, Steel 1002 and SQ476, see the Products Page for a description of each and the Technical Documentation.

Consult the product TDS for the correct product for your corrosion zone, we have a system available from C1 right through to C5 exterior.

Compliance is at the core of what we do because this is what saves lives, and all Fireshield timber and steel intumescent products have full building code compliance in both New Zealand and Australia.

Here at Fireshield, we are involved in the development, manufacture, all fire testing and compliance certification for all of our products. 

See each of the individual product TDS’ for the full country-specific compliance pathway for each product.

For Australia only, see the Codemark Certificate and Codemark Guide in the documents section, and to make specifying Fireshield timber products even simpler, download and complete the Fireshield Codemark Form. This form shows the Certifier that you have complied with the conditions and limitations of the CodeMark and achieved compliance with the NCC 2019 amendment 1.

Why Fireshield?

Fireshield steel systems can be specified using primers and top coats from all the major paint manufacturers around the globe, in New Zealand and Australia. All primers and top coats must be approved by Fireshield for use with our intumescent products to produce a warrantable, compliant system, see our approved lists in the documents section.

Fireshield Steel 1001 and Steel 1002 coatings are the only intumescent products available in New Zealand and Australia with Declare Status and are Red List Free, this gives you an environmentally friendly coating option for 30 to 120-minute protection for interior steel.

What is Declare? Declare provides a free and simple database of the healthiest products on the market. The transparency labels were created from the need of Living Building Challenge project teams who must meet stringent materials requirements within the worlds most rigorous building performance standard. Check out the Living Future Institute Australia and in New Zealand

Steel 1001 is one of the only intumescent products available with 60 mins FRR that can be used in conjunction with timber strapping directly attached to the coated steel member thanks to our testing laboratory. The ability to attach timber to the coated steel removes any confusion on site for the Contractor, see our Cladding Study in the documents section.

Fireshield SQ476 is our single pack solvent option that can be used as a complete Fireshield warranted exterior system for structural steel. This must be ordered specifically for your project to ensure we have the topcoat colour you want for your project. SQ476 can also be used for interior steel, its fibre free, smooth finish is designed for exposed steel sections that require up to 120-minute FRR protection, it can be top-coated any colour.
