Cladding product fire testing
This page is intended for industry professionals to increase collective understanding of the performance characteristics of various cladding types.
A variety of cladding types have been identified on buildings referred to Cladding Safety Victoria (CSV), and a range of tests on these products are being conducted to increase our understanding of the performance of these products and the degree of risk they pose in the event of fire.
This product testing is ongoing and over time additional information will be made available on this website as further tests are undertaken. The tests were undertaken by a NATA accredited testing laboratory.

Fire testing methodology
CSV’s tests are based on various standards such as ISO 13785-1, ISO 9705-1, BS 8414, and AS 5113. However, these standardised tests are not fully utilised because CSV aims to holistically and individually evaluate the cladding and the variable components that make up the wall, rather than relying on a rating, classification, or pass/fail criterion for the cladding product and wall system.
The tests are tailored to specific scenarios, particular building configurations and realistic fire exposures based on what is found within the portfolio of buildings referred to CSV. These tests are data-driven, and at times iterative, designed to assess and understand the performance of under ‘as-built’ conditions, evaluating not only the cladding but contribution of the other components that make up the overall wall system.
Product, materials and composition
Below lists the types of products that have been tested and the composition of the core of each product. The selection of these products is based on what was most commonly found on buildings referred to CSV. The composition of combustible material in each product, including polymer and flame retardant content, is shown as a weight percentage.
Aluminum Composite Panels (ACP)
The naming convention adopted for the various ACP panels tested revolves around the presence of flame retardant (FR) or lack thereof. For instance, ACP-FR70 refers to an ACP panel comprised of approximately 70% FR, while ACP-NFR45 refers to a panel which has approximately 45% non-flame retardant (NFR) filler, such as calcium carbonate. For ACP-PE, the ‘PE’ denotes all types of polymers, with polyethylene being the most commonly present.
| Cladding type | Polymer content | Flame retardant content | Other content |
|---|---|---|---|
| ACP-FR70 | 26.0% | 73.4% (Aluminium Trihydroxide) | - |
| ACP-FR45 | 43.9% | 45.3% (Magnesium Hydroxide) | - |
| ACP-NFR45 | 49.8% | - | 47.9% (incl. 40.2% Calcium Carbonate) |
| ACP-PE | 96-100% | - | 0-4% (inert material) |
Expanded Polystyrene (EPS)
Expanded Polystyrene (EPS) is a lightweight, rigid polymeric foam derived from the monomer styrene. When used as external cladding, EPS is typically covered with a render for protection and finish. Although EPS can come in various compositions, it is classified as such because polystyrene constitutes most of its composition.
CSIRO research
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) has published research into the aforementioned cladding products.
In May 2020, CSIRO published research into the fire performance and test methods for ACP external wall cladding. Download the report below.

In September 2020, CSIRO published a peer review about fire safety of exterior insulation finish systems and insulated sandwich panels, external wall systems and a witness report of an AS5113 test on rendered EPS. Download both reports below.
Peer reviewed research
ACP flame retardant
CSV published peer reviewed research in Chapter 5 of Construction Materials and Their Properties for Fire Resistance and Insulation (Elsevier, October 2024)(opens in a new window). This chapter describes CSV’s research and evidence of the flame growth index and heat release rate of relevant materials. This research demonstrates that polymer content alone is not determinative of combustibility, but the percentage of fire retardant or other fillers will have a significant impact on the performance of a product in a fire. CSV encourages professional engineers to access the most up-to-date evidence about cladding risks by studying this peer reviewed chapter.
This research is also reflected in D.01 Cladding and Materials(opens in a new window) in CSV’s Protocols for Mitigating Cladding Risk (PMCR)(opens in a new window).
Influence of cladding and insulation materials on facade fire spread
CSV and RMIT University examined how different cladding and insulation materials influence external fire spread using medium-scale ISO 13785-1:2002 testing under a calorimetric hood in accordance with ISO 9705-1:2016 in addition to Fourier-Transform Infrared Spectroscopy (FTIR) gas analyser in accordance with ISO 16405:2015 and ISO 19702:2015.
Ten tests were undertaken using combinations of ACP-FR70, ACP-FR45 and ACP-PE panels, each paired with rockwool, polyethylene terephthalate (PET) or no insulation. A baseline test using aerated concrete with no insulation was also conducted.
The study describes and evidences that the influence of cladding composition, especially the polyethylene content, has a far greater influence and contribution on heat release and flame spread than insulation type.
Key findings, data and analysis is detailed in the paper which can be downloaded below.
Test reports and videos
It is highly recommended to view both the test reports and videos, where available, as they are complimentary pieces of information.
Aluminum Composite Panels (ACP)
CSV’s investigation of ACP includes several distinct series of tests. Despite variations among each series, such as differences in cladding composition, variations in internal insulation, exposure conditions, and duration, the general structure of each test series falls into one of the three configurations. The tests conducted were International Organisation for Standardisation (ISO) tests designed in accordance with general requirements outlined in ISO 13785-1:2002, incorporating a heating rate defined in ISO 9705-1:2016. The configuration of the wall cavity reflected real case scenarios which provide valuable insights and practical evidence to the performance of the cladding and external influence of a wall cavity and wind.
ACP-FR70
The tests that have been completed relating to ACP-FR70 are below with supporting reports and videos.
Open all
- ACP-FR70 Vertical fire spread testing
Three repeated tests were conducted with ACP-FR70 and a combination of rockwool and polyester insulations behind. The tests were designed according to general requirements outlined in ISO 13785-1:2002, incorporating a heating rate defined in ISO 9705-1:2016. These tests aimed to replicate scenarios where an internal fire could ignite ACP-FR70 and enter the cavity behind it. The dimension of the specimens was 3.6 metres high by 1.2 metres wide. The cladding was constructed as two folded cassette fixed panels (with gaps between the panels being less than 20mm). This is representative of a building in CSV’s program.

Three repeated tests were conducted with ACP-FR70 and polyester insulation behind. The tests were designed according to general requirements outlined in ISO 13785-1:2002, incorporating a heating rate defined in ISO 9705-1:2016. These tests aimed to replicate building fire scenarios that could potentially ignite the ACP-FR70 in the following possible situations:
-
An internal fire that ignites nearby cladding via flame extension through a window or door opening.
-
A fire within an external wall due to electrical fault within the wall.
-
Direct flame flareup from a BBQ, nearby light fixture or electrical failure, or stored combustibles ignited by a cigarette on the balcony.
-
Exposure to fire from adjoining allotments. Dimension of the specimens was 3.6 metres wide by 3.6 metres high. The specimen comprised of three modules, interconnected through aluminium framing. The front face of the specimen was cassette cladded (with gaps between the panels being less than 20mm) whereas the backside was closed off with discontinuous steel back-pan. Within the cavity, polyester insulation was fixed to the back-pan using fast-fix washers and pin combinations. The specimen constructed is representative of a building in CSV’s program.

ACP-FR70 - Blanket wall testing
- ACP-FR70 Influence of wind on fire spread and baseline testing
Baseline testing
Before conducting the specific test involving the ACP-FR70, a baseline test was executed using a non-combustible blanking wall to gather baseline data regarding heat, wind speed, and flame spread under both windy and calm conditions.
ACP-FR70 External wind testing
The construction is identical to the specimen used in the horizontal fire spread, with the addition of a wind force from fans guided by a non-combustible wing wall and a heating rate of 300 kW. The airflow was directed at a 45-degree angle to the specimen’s face at an approximate speed of 2.5 metres per second, coinciding with the point where the wind meets the edge of the specimen. The singular test involving ACP-FR70 and polyester insulation behind, mirrored the setup in of the horizontal fire spread test. The only deviation is the burner’s placement, which was located on the opposite side of the specimen. The dimension of the specimens was 3.6 metres high by 3.6 metres wide. The specimen comprised of three modules, interconnected through aluminium framing. The front face of the specimen was cassette cladded (with gaps between the panels being less than 20mm) whereas the backside was closed off with discontinuous steel back-pan. Within the cavity, PE insulation was fixed to the back-pan using fast-fix washers and pin combinations. The specimen constructed is representative of a building in CSV’s program.

- ACP-PE Balcony vertical fire spread testing
This test series was conducted to investigate the influence of the balcony depth on the vertical fire spread of facades via ACP-PE. Four similar tests were conducted on ACP-PE infill panels with rock mineral sandwich panel followed by a layer of polyester insulation. There was some variation between the tests summarised below:
| Test description | |
|---|---|
| Test 1 | 300 kW (540 MJ) heat source with no glass balustrade included on the upper floor |
| Test 2 | 500 kW (900 MJ) heat source with no glass balustrade included on the upper floor |
| Test 3 | 500 kW (900 MJ) heat source with inclusion of glass balustrade included on the upper floor |
| Test 4 | 500kW (900 MJ) heat source with inclusion of glass balustrade included on the upper floor. This is a repeat of test 3. |
| The tests were designed according to general requirements outlined in ISO 13785-1:2002, incorporating a burner specified in the ISO standard. The test was a replica of a building within CSV’s program where there is a slab protrusion between floor levels with discontinuous infill ACP-PE cladding on different floors. The slab protrusion is designed as a narrow balcony and has a lip on its edge. The effectiveness of this horizontal protrusion in preventing external fire spread via ACP-PE can be evaluated from this test series. |

Expanded Polystyrene (EPS)
CSV’s investigation of EPS was driven from a data perspective and to identify energy contribution of the cladding and auxiliary components of the wall system and as a comparison against other cladding types in a similar configuration.
- EPS Fire testing
The tests conducted were based on International Organisation for Standardisation (ISO) tests designed in accordance with general requirements outlined in ISO 13785-1:2002, with the specimen burnt under the exhaust hood and heating rate as both defined in ISO 9705-1:2016 with an extended burn time (if not terminated earlier).
Dimension of the specimens was 1.5 metres wide by 2.5 metres high. The mounting frame, made of 92 mm steel framing secured with screws, served as the cavity and main support for the test specimen. The steel frame was covered with weatherproof wrap, with a 200 mm overlap at the joints, which were taped for sealing. EPS panels were cut to size, mounted onto the steel frame, and screw-fixed to the studs with washers. Corner beads were nailed to the edges, and a cement-based render base coat was applied, reinforced with mesh, and covered with the additional same base coat to reach a 5 mm thickness. After curing, a 3 mm acrylic topcoat was applied, followed by two layers of water based acrylic membrane coating. The test omitted components typically found in a wall system on buildings, such as insulation and sarking.
There were slight variations between the three tests pertaining to the capping detail and width of the specimen as follows:
- Test 1: Right angle steel flashing at the underside of the cladding; specimen width remained at 1.5 metres
- Test 2: Z angle steel flashing at the underside of the cladding; specimen width remained at 1.5 metres
- Test 3: Right angle steel flashing at the underside of the cladding; specimen width increased to 2.4 metres Watch videos of the three fire tests below.
