Fibre Reinforced Facade Encyclopedia: Testing and standards
Facade fire safety is the set of design, testing and verification requirements that limit the spread of fire over and within the external wall of a building. It is a property of a complete wall system assessed for a particular building, not a property of any product. No cladding panel is fire safe on its own, and no test result makes a facade safe; what a test result does is establish one fact about one component or one tested assembly, which a designer and a certifier then use to decide whether a specific wall on a specific building meets the code.
This page is an orientation, not an answer. If you have arrived searching for fire safe cladding, the useful question is not which product is safe, but which compliance route the building is on and what evidence that route requires.

Why no product is fire safe
Cladding fires do not spread because one material was chosen. They spread because of how a system behaved: a combustible layer in the build up, a continuous cavity acting as a chimney, insulation or a membrane contributing fuel, barriers missing or badly installed, openings too close together vertically. Any one of those can sit behind a panel holding an excellent test certificate.
This is why the codes have moved toward assessing the assembly. AS 5113 in Australia, BS 8414 with the BR 135 criteria in the United Kingdom and NFPA 285 in the United States all build a full-scale section of the real wall and burn it, because the interaction between the layers is what matters and no material test can see it.
The three different things people mean by fire rating
Most confusion in facade specification comes from three separate ideas being collapsed into the phrase fire rating. They are measured by different tests, on different subjects, and they are not substitutes.
- Non-combustibility is a material property, decided by a furnace test at about 750 °C: AS 1530.1 in Australia, EN ISO 1182 in Europe, ASTM E136 in the United States. The answer is yes or no
- Reaction to fire covers everything else about how a material burns: flame spread, heat release, smoke and droplets. It is graded, as a group number under AS 5637.1, a class such as B-s2,d0 under EN 13501-1, or a flame spread index under ASTM E84
- Fire resistance is an assembly property, measured in minutes under AS 1530.4 or EN 13501-2. It belongs to a wall, floor or door, never to a cladding panel
A fourth category sits outside all three: the full-scale facade test, which assesses the wall system rather than a material or an element. The pages on non-combustibility, reaction to fire and fire resistance level set out each of these in detail.
What actually governs a facade in Australia
The starting point is the type of construction, read from the building’s class and rise in storeys. For Type A and Type B construction, NCC 2022 Volume One clause C2D10 requires the external walls, and anything attached to them, to be non-combustible, meaning not deemed combustible when tested to AS 1530.1. That is the Deemed-to-Satisfy route, and it is a document check.
Where the cladding is not non-combustible, that route is unavailable and the design must satisfy the relevant Performance Requirement directly. In practice this means Verification Method C1V3, whose central condition is a full-scale AS 5113 test of the wall system as it will be built, with further conditions including sprinklers and cavity barriers, assembled into a Performance Solution by a fire engineer and accepted, or refused, by the certifier.
Alongside both routes sit requirements that apply regardless of the cladding: fire resistance levels under Specification 5, fire hazard properties under Specification 7, and vertical separation of openings under Part C3. A facade is not compliant because the panel passed a test; it is compliant when every one of these has been addressed.
What to check on a real project
- Which type of construction the building is, because that decides whether the non-combustibility requirement applies at all
- Which route the project is on, Deemed-to-Satisfy or Performance Solution, decided before the facade is designed rather than after
- Every layer, not just the panel: insulation, membrane, sarking, sealants, brackets, framing and any attachment
- The cavity barrier strategy, including type, depth and where each barrier goes
- Whether the wall as detailed matches the wall as tested, if a full-scale test result is being relied on
- The evidence trail: test reports naming the standard, the test body, the report number and the tested configuration
- Installation and verification on site, because a barrier that is not continuous is not a barrier
The last point is not a formality. Most defects found in facade inspections are workmanship and substitution issues: a barrier cut around a bracket and not made good, a membrane swapped for a cheaper one, a sealant chosen for adhesion rather than fire performance.
Choosing a material with the route in mind
The choice of facade material is, in fire terms, a choice of compliance route. A non-combustible material puts the project on the prescriptive route, with a shorter and more predictable approval path. A combustible material opens geometry and weight the prescriptive materials cannot deliver, and commits the project to a fire engineering process with a certifier at the end who can decline.
For the ShapeShift systems the position is stated plainly. ShapeShell-RC, the glass fibre reinforced concrete system, is Not Deemed Combustible under AS/NZS 1530.1, tested by Ignis Labs, at 30 to 50 kilograms per square metre. ShapeShell-RT, the fibre reinforced polymer system, is combustible; it cannot pass AS 1530.1, EN ISO 1182 or ASTM E136, and it is never described as non-combustible. It holds an AS 5637 Group 1 classification from AWTA Product Testing, an EN 13501-1 class of B-s2,d0 from Intertek Testing Services, and it passed the full-scale BS 8414 and AS 5113 test at BRE Global, which is the evidence a Performance Solution is built from.
Neither of those statements says a facade is safe. Safety is assessed for a building, by people with the authority and the liability to assess it.

Questions specifiers ask
What is the safest cladding material?
The question has no answer at product level. Safety is a property of a wall system assessed for a particular building. A non-combustible material tested to AS 1530.1 puts a project on the simpler compliance route, but insulation, membranes, cavity barriers, openings and workmanship all determine how the facade performs.
Is non-combustible cladding automatically compliant?
No. Non-combustibility satisfies one requirement, C2D10. The wall may still need a fire resistance level under Specification 5, vertical separation of openings under Part C3, compliant insulation and sarking, and cavity barriers to the building’s fire strategy.
What does a full-scale facade test prove?
That one specific wall build up, with its cladding, cavity, insulation, membrane and barriers, behaved within the criteria of that standard on that rig. It is evidence about a configuration, not an approval of a product, and it does not transfer to a different wall.
Who decides whether a facade complies?
The building surveyor or certifier, working from the code, the test evidence and, on the performance route, a fire engineer’s report. Some jurisdictions also require referral to the fire authority, and a certifier can refuse a Performance Solution.
Where should I start on my project?
With the type of construction and the compliance route, before the facade is designed. The deemed-to-satisfy and performance solution pages set out the two routes, and the NCC external walls page sets out the clauses that apply.
ShapeShift publishes every fire result by standard and testing body, including what each system is not tested for, so the evidence review starts from documents. See ShapeShell fire test data
