4 INTRODUCTION General The purpose of this assessment is to evaluate a Performance Solution of the Euro Clad product to satisfy the performance requirements of the National Construction Code Volume One and Two Building Code of Australia (BCA). The assessment evaluates the product as an internal and external wall lining/attachment to loadbearing or non-loadbearing walls that do or do not require a Fire Resistance Level. The following clauses of the BCA have been evaluated and identified as being complied with: CP2(a) Building elements avoid the spread of fire, P2.3.1 Protection from the spread of fire The Euro Clad building element has been tested in accordance with AS Methods for fire tests on building materials, components and structures Simultaneous determination of ignitability, flame propagation, heat release and smoke release, AS/NZS 3837:1998 Method of test for heat and smoke release rates for materials and products using an oxygen consumption calorimeter and AS 5113 Fire propagation testing and classification of external walls of buildings. The testing has demonstrated the for the proposed installation locations that they do not present an independent fire hazard or risk of fire spread. Clause C1.1 Type of Construction Required Specification C1.1 Clause 2.4 Attachments not to impair fireresistance o The combustible components and assembly complies with the fire hazard properties of Specification C1.10 Clause 7 table 4 o When located near or directly above a required exit does not make the exit unusable in a fire o Does not otherwise constitute an undue risk of fire spread via the façade of the building o The attachment does not impair the required FRL of that part. CP4 Fire hazard properties of materials The Euro Clad building element has been tested in accordance with AS/NZS 3837:1998 to achieve a Group 3 rating and therefore satisfies CP4 and subsequently Clause C1.10 where a Group 3 material is permitted on a wall or ceiling. Clause C1.10 Fire Hazard Properties Sub-clause (a)(ii) wall linings and ceiling linings that comply with Specification C1.10 Clause 4 Sub-clause (a)(ix) Other materials that comply with Specification C1.10 Clause 7 Clause G5.2 Bushfire Protection (including associated State variations) Part Bushfire Areas AS 3959 Construction of buildings in bushfire-prone areas BAL 12.5 to 29. Product Detail The Urbanline Euro Clad Selekta Panel is a pre-finished composite cladding façade with a timber-grained-embossed surface. Designed for stability and longevity with purported to be eco-friendly maintenance free and easy to install. The Euro Clad Selekta Panel is 170mm in width with a 155mm cover, 18mm in thickness and up to 5400mm in length. The maximum fixing span is 625mm. The Euro Clad Selekta Panel achieves a Spread of Flame Index of 0 and Smoke Development Index of 3 when tested to AS :1999 and a group 3 number when tested to AS/NZS 3837:1998. Product Identification The Euro Clad panel can be identified by the unique product profile as well as its delivery packaging as detailed below. FIGURE 1: Product Identification Panel Fixing and Installation The Euro Clad panel can be mechanically fixed to the wall frame via a top hat or timber sub-frame, to allow for a breathable air cavity to Type A and B or Type C construction respectively provided the wall and subframe comply with the requirements of the BCA. The fixing is to be at centres no greater than 625mm as detailed below. This includes when installed on the diagonal. FIGURE 2: Installation Figure example The Euro Clad Selekta Panel has been evaluated by Summermore Structural and Civil Engineers in accordance with the BCA, AS/NZS :2002, AS/NZS :2002, AS1720.1:2010 and AS 1684:2010. The analysis detailed that the Euro Clad Selekta Panel has a maximum fixing spacing of 645mm for general cladding areas and 300mm for areas within 1200mm of corners. The analysis excluded considerations for impact resistance as required for cyclonic areas under AS/NZS :2011. This applies to N1 to N4 and C1 to C3 applications. Urbanline has limited the maximum spacing to 625mm with 30mm long 6 gauge stainless or galvanised steel screws. Limitations The Euro Clad product can be installed on walls or ceilings on the internal or external parts of walls. When installed on the exterior of a wall the Euro Clad product is to be in a single vertical plane only. I.e. if installed on an external wall, any return or wing wall (at an angle less than 90) is not permitted to have the Euro Clad product installed. This does not limit the Euro Clad being installed on an external wall as well as ceiling or eve portion of a building I01R00 URBANLINE COMPLIANCE NCC ANALYSIS DOCX PAGE 4 OF 11

5 FIRE SAFETY AND INSTALLATION REQUIREMENTS Scope of Use The Euro Clad Selekta Panel is permitted to be used, on the interior or exterior side of the wall frame or structure, vertically, horizontally on a soffit of a building, awning, architectural feature or the like attached to a wall.

6 EURO CLAD PERFORMANCE SOLUTION BCA Deemed-to-Satisfy Basis It is proposed to permit the use of the Euro Clad Selekta Panel as a decorative façade or wall lining in multiple configurations. This includes an internal or external ceiling/roof or wall lining or external attachment, in accordance with both Volume One and Two of the National Construction Code. BCA Performance Requirement The relevant BCA Performance Requirements are CP2(a)(iii), CP4 and P Meeting the Performance Requirement The Performance Requirement will be satisfied by A0.2 (c): a combination of (a) and (b) where (a) is a Performance Solution and (b) is a Deemed-to-Satisfy Solution. Assessment Method BCA Provision A0.5 (b)(ii) Verification Methods as the appropriate authority accepts for determining compliance with the Performance Requirement. Methodology The following methodologies will be applied to the evaluation: þ Absolute þ Quantitative þ Deterministic The following images detail some common acceptable applications for the Euro Clad. It is important to note the application along single planes and not on two walls at right angles to each other. FIGURE 3: TYPICAL APPLICATIONS FOR EURO CLAD o Comparative þ Qualitative o Probabilistic Absolute approach As outlined in the International Fire Engineering Guideline an absolute approach is typically when an evaluation is carried out on an absolute basis, the results of the analysis of the trial design are matched, using the agreed acceptance criteria against the objectives or performance requirements without comparison to deemed-tosatisfy or prescriptive or benchmark designs. Quantitative approach A quantitative approach refers to an analysis that involves numerical evaluation of an identified process. The quantitative approach includes detailed mathematical and engineering calculations. Qualitative approach A qualitative approach refers to descriptions or distinctions based on a quality or characteristic rather than on a quantity or measures value. The qualitative approach includes structured arguments to demonstrate compliance. Deterministic approach A deterministic approach is a methodology based on physical relationships derived from scientific theories and empirical results that for a given set of conditions will always produce the same outcome. Acceptance Criteria The acceptance criteria for this performance solution is that the Euro Clad material has the required fire hazard properties, group number and via the full scale fire test to the degree necessary, avoids the spread of fire between buildings. Identified Hazard The potential hazard is that a fire may occur and spread via the Euro Clad Panel 5130 I01R00 URBANLINE COMPLIANCE NCC ANALYSIS DOCX PAGE 6 OF 11

7 External Application The construction of walls defined within the BCA consists of three principle elements, internal linings, the wall itself and external attachments. This part of the evaluation is focused on external attachments, linings, veneers and the like. The BCA permits combustible assemblies to be attached to external walls depending on two scenarios. The first is where the wall requires a Fire Resistance Level and the second is where no Fire Resistance Level is required. Both these scenarios require compliance with Performance Requirement CP2. For external installations, the BCA requires, in accordance with Clause C1.10, compliance with Specification C1.10, Clause 7 table 4 where the spread of flame and smoke development indices are less than that permitted by the BCA. Table 4 also requires the member or assembly to retain the protection in position so that it prevents ignition of the material and continues to screen it from access to free air for a period of not less than 10 minutes. Where the wall is to achieve a Fire Resistance Level, compliance with Specification C1.1 Clause 2.4 is required. This clause reiterates compliance with Specification C1.10, not located such to make the exit unusable in a fire and does not otherwise constitute an undue risk of fire spread via the façade of the building. An evaluation of the relevant clauses and testing requirements for the use of the panel as an external attachment is detailed below. CP2 Performance Evaluation BCA Performance Requirement CP2(a)(iii) is identified as the relevant performance requirement for the use of the material in an external application. The other elements relate to internal design or wall requirements such as fire rated compartmentation. TABLE 1: PERFORMANCE REQUIREMENT CP2 (A)(III) (a) A building must have elements which will, to the degree necessary, avoid the spread of fire- (iii) between buildings Source: BCA 2016 Fire spread between buildings can occur due to the spread of fire being greater than a permitted opening resulting in the radiant heat flux exceeding the values permitted under CV1 or CV2. It has been identified via various publications that there is no deemed to satisfy provision for demonstrating an external wall element to avoid the spread of fire. These reference documents include: - VBA Fact Sheet Non-Deemed-to-Satisfy External Wall Cladding Systems issued April Victorian Building Control Commission, Fire Protection for High- Rise Buildings The fire protection research foundation, fire hazards of exterior wall assemblies containing combustible components June SAMFS Combustible external cladding materials to buildings letter dated 30 December Australian Senate Economic References Committee, nonconforming building products interim report Safety not a matter of good luck May ABCB Regulatory Impact Statement non-compliant use of external cladding products on buildings August 2016 Specification C1.1 Clause 2.4 details a requirement for attachments not to impair fire-resistance. AS 5113 External Façade Test AS 5113 provides procedures for the fire propagation testing and classification of external walls of buildings according to their tendency to limit the spread of fire via the external wall and between adjacent buildings. AS 5113 is applicable to fire propagation via all external vertical or near vertical surfaces and covers all types of external wall systems, including facades, outer skins, core materials, cavities and attachments. AS 5113:2016 is not a reference document within the National Construction Code. It is anticipated that this will occur in the 2019 version of the NCC. The following evaluation considers the results from AS 5113 in context to the requirements of CP2. AS 5113:2016 section 6 sets conditions on the reporting of the classification. A report is required to prepared independently to the fire test. BS 8414 Fire performance of external cladding systems. Test methods for non-loadbearing external cladding systems applied to the face of a building. As detailed above, the BS 8414 external wall fire test, as referenced in AS 5113 is intended to simulate the multi-storey flammability fire performance of an entire external wall assemblies. It involves the construction of a two-storey test rig clad in the subject product which is subjected to a fire source consisting of a timber crib. The pass/fail criteria is based on flame propagation vertically and laterally across the subject material, which is measured by various thermocouples and observations of flames emitting from the surface of the specimen at specific locations. This standard is considered to be a very good indicator of the as-installed fire performance of an external cladding material because it is a large scale test designed to mimic real installations. The products testing to BS 8414 was undertaken by BRE Global within their indoor facility. BRE Global operates one of the largest fire research and testing laboratories in Europe being accredited by UKAS The testing occurred on 7 July The test report details that the BS 8414 test apparatus is used to evaluate the fire propagation characteristics of exterior non-load-bearing wall assemblies and panels used as components of curtain wall assemblies that are constructed using combustible materials or that incorporate combustible components within the wall assemblies as specified in the following: The ability of the wall assembly to resist flame propagation over the exterior face of the wall assembly. The ability of the wall assembly to resist vertical flame propagation within the combustible core or within other combustible components from one storey to the next. The ability of the wall assembly to resist vertical flame propagation over the interior surface of the wall assembly from one storey to the next. The ability of the wall assembly to resist lateral flame propagation from the compartment of fire origin to adjacent compartments or spaces. The AS 5113 test was undertaken with the support of the BRE. The wall consisted of the following makeup: 13mm standard grade Plasterboard 75mm Lightweight steel Frame Fibre cement sheet Glasswool fibre insulation Tyvek sarking 61mm Furring channels Euro Clad panel The following table details the results of the test against the requirements of AS I01R00 URBANLINE COMPLIANCE NCC ANALYSIS DOCX PAGE 7 OF 11

8 TABLE 2: AS 5113 ACCEPTANCE CRITERIA Test Requirements T w5m <600 C Pass/Fail PASS The peak temperature of 500 C at approximately 12 minutes Flame spread beyond the confines of the specimen in any direction, as determined during the post-test examination, shall not occur. The examination shall include flame damage such as melting, charring but not smoke discolouration or staining of the surface, any intermediate layers and the cavity. T cavity5m <250 C PASS The peak temperature was 107 C at about 20 minutes when the test was terminated T Unexposedside0.9m <180 C PASS The peak temperature of 180 C was not reached PASS single plane only Based on a comparison between the charring and the test, the flame damage through the Euro Clad panel occurred in the area of direct flame impact. After 17 minutes, pyrolysation of the wing wall occurred causing the Euro Clad to ignite. This resulted in spread past the confines of the specimen resulting in the test being terminated. Continuous flaming on the ground for more than 20 s from any debris or molten material from the specimen shall not occur. PASS Analysis of the debris detailed that on average the debris flamed in the order of 10s and each element of debris did not flame for longer than 20s. During the test debris from the crib as well as the external façade Debris mass <2kg mixed together limiting the capacity for the debris mass to be determined. Source: BCA 2016 From the above test results, fire spread occurred due to the radiation exposure on the wing wall after almost 20 minutes. This is consistent with table A3 of AS where non-piloted ignition of timber occurs after a long time. With a limitation of excluding a wing wall installation, the Euro Clad panel does not cause spread of fire outside of the fire itself I01R00 URBANLINE COMPLIANCE NCC ANALYSIS DOCX PAGE 8 OF 11

9 Volume Two bushfire areas The Euro Clad Selekta Panel has been tested in accordance with the requirements of AS to a rating of BAL 29 by Exova Warrington in their test report AS Clause 5.4, 6.4 and 7.4 for BAL 12.5 and BAL 29 Bushfire Attack Level: 29 Required Fire Safety Measures Based on the testing of the Euro Clad Selekta Panel to AS 5113, the Euro Clad Selekta Panel can be installed as an external element of a wall provided it is used on a single plane of a wall or external soffit with any wing or return wall at 90 or less constructed of non-combustible material. Equally the Euro Clad panel is permitted to be used in areas where a BAL 29 requirement is applied. Evaluation Summary In the opinion of Ignis Solutions, the assessment has demonstrated that the Euro Clad panel can be used on a single plane of a wall or external soffit with any wing or return wall at 90 or less constructed of noncombustible material and therefore in these locations satisfies the requirements of BCA Performance Requirement CP2 (a)(i), (ii) and (iv). As well as P2.3.4 for bushfire. Internal Application The BCA details a number of provisions for the use of building elements within a building. This includes Performance Requirement CP2(a)(i)(ii) and (iv) as well as CP4 as detailed below. TABLE 3: PERFORMANCE REQUIREMENT CP2 (a)(i), (ii) AND (iv) (a) A building must have elements which will, to the degree necessary, avoid the spread of fire- (i) to exits; and (ii) to sole-occupancy units and public corridors; and (iv) in a building Source: BCA 2016 TABLE 4: PERFORMANCE REQUIREMENT CP4 To maintain tenable conditions during occupant evacuation, a material and an assembly must, to the degree necessary, resist the spread of fire and limit the generation of smoke and heat, and any toxic gases likely to be produced, appropriate to- (a) the evacuation time; and (b) the number, mobility and other characteristics of occupants; and (c) the function or use of the building; and (d) any active fire safety systems installed in the building. Source: BCA 2016 To satisfy the requirements of CP2 (a)(i), (ii) and (iv) as well as CP4 compliance through the Deemed-to-Satisfy Clause C1.10(ii) for Fire hazard properties is required for wall linings and ceiling linings as well as attachments and other materials. The BCA sets the principle requirements for fire hazard properties of building materials within Part A2 Clause A2.4 for where building components or assemblies are to have fire hazard properties. Clause A2.4 requires compliance in accordance with Specification A2.4. Specification A2.4 Fire Hazard Properties sets the scope for determining the fire hazard properties of assemblies to be tested to AS/NZS The construction of walls defined within the BCA consists of three principle elements, internal linings, the wall itself and external attachments. For internal installations, the BCA requires, in accordance with Clause C1.10, compliance with Specification C1.10, Clause 7 table 4 where the spread of flame and smoke development indices are less than that permitted by the BCA. Table 4 also requires the member or assembly to retain the protection in position so that it prevents ignition of the material and continues to screen it from access to free air for a period of not less than 10 minutes. Where the wall is to achieve a Fire Resistance Level, compliance with Specification C1.1 Clause 2.4 is required. This clause reiterates compliance with Specification C1.10, not located such to make the exit unusable in a fire and does not otherwise constitute an undue risk of fire spread via the façade of the building. An evaluation of the relevant clauses and testing requirements for the use of the panel as an external attachment is detailed below. Clause C1.1 Type of construction required Clause C1.1 of the BCA sets the type of construction required within a building as per Table C1.1 where construction of Type A, B or C is required dependent on the buildings rise in storeys. Clause C1.1 sets the requirement for compliance with Specification C1.1 of the BCA. The guide to the BCA details that the intent of Clause C1.1 is to establish the minimum fire-resisting construction required for Class 2-9 buildings with Specification C1.1 providing clarity that Specification C1.1 contains requirements for fire-resisting construction of building elements. Specification C1.1 requirements and the associated compliance are detailed below. Based on compliance against Specification C1.1, compliance with Clause C1.1 as well as Performance Requirement CP2 and CP4 is deemed satisfied. Specification C1.1 Clause 2.4 Specification C1.1 Clause 2.4 sets criteria for attachments to buildings to not impair the fire-resistance. The guide to the BCA clarifies the intent as being to minimise the risk that a finish, lining or attachment to a wall or roof required to have a fire-resistance level (FRL) will: Impair the FRL of the wall or roof to which it is attached; Compromise the safe evacuation of the building; and Lead to the spread of fire by way of the building façade. Note: It is important to note that in some circumstances, an FRL of - /-/- can be considered a required FRL and therefore in some circumstances by the Authority Having Jurisdiction Specification C1.1 Clause 2.4 remains valid for all wall scenarios. The guide goes on further to state: Specification C1.1 Clause C2.4 does not prohibit the use of combustible materials as a finish, lining or other attachment to a wall, roof or other building element required to have an FRL. The combustible material can only be used if the material: a. Is one of the exemptions from fire hazard properties listed in C1.10 (c), or complies with the fire hazard properties prescribed in Specification C1.10; b. Is not located in a position to make a required exit unusable in a fire, therefore it will not compromise the building s safe evacuation; c. Will not lead to the spread of fire by way of the building façade d. Will not impair the FRL of the wall, roof or other building element to which it is attached. It is noted that Clause 2.4(a) only applies to the use of finishes or linings, and other attachments. Clause 2.4(b) prohibits a required FRL of a building part from being reduced by the attachment of facings or finishes. a. The Euro Clad Selekta Panel has had its core material as well as the 5130 I01R00 URBANLINE COMPLIANCE NCC ANALYSIS DOCX PAGE 9 OF 11

10 full assembly tested in accordance with AS The material achieved the following results: Fire Hazard Properties Spread of Flame Index 0 Smoke Development Index 3 These results provide a Spread of Flame Index as well as Smoke Developed Index less than that of the fire hazard properties prescribed in Specification C1.10 being a maximum of 8 and 9 respectively. b. The Euro Clad Selekta Panel is not permitted to be used within a fire isolated stair, ramp or passageway. When used in or near a required exit, internal to the building, it satisfies the requirements of Group 3. When used external to a building, the panel has not been observed to burn unless a substantial fire event was located within proximity to the panels. In this scenario, it would be the fire event that renders the required exit unusable and not the panel. Based on the testing of the panel, compliance against Specification C1.1 Clause 2.4 with assistance from the Guide to the BCA has been demonstrated. Clause C1.10 Fire hazard properties Clause C1.10 sets two conditions for the use of the Euro Clad Selekta Panel within buildings. The first is through sub-clause (a)(ii) being internal wall and ceiling linings and the second is sub-clause (a)(ix) other materials and locations. Clause C1.10 requires the fire hazard properties to comply with Specification C1.10. Specification C1.10 For wall and ceiling linings compliance with Clause 4 and subsequently establishment of a Group number is required. Testing of the Euro Clad Selekta Panel results in a group 3 material. The Euro Clad Selekta Panel is permitted to be used internally in the locations designated for group 3 products in the following table as extracted from the BCA Specification C1.10 Clause 4 table 3. FIGURE 4: BCA SPECIFICATION C1.10 TABLE 3 Testing of the Euro Clad panel is detailed as follows: AS/NZS 3837:1998 Method of test for heat and smoke release rates for materials and products using an oxygen consumption calorimeter. EXOVA Warrington has undertaken testing of the product in accordance with AS/NZS 3837 in their report cb.1. Exova Warrington is a Registered Testing Authority with the National Association of Testing Authorities. The test report was issued on 05 August 2015 and produced the following results: Group Number: 3 For other materials and locations, Clause 7 table 4 requires materials and assemblies not to exceed the indices listed. FIGURE 5: BCA SPECIFICATION C1.10 TABLE 4 indices listed, compliance with Specification C1.10 is achieved and subsequently Clause C1.10.

The Australian Wool and Textile Authority (AWTA) is a Registered Testing Authority with the National Association of Testing Authorities accreditation Testing to AS is within AWTA scope of testing. The test report was issued on 02 August 2012 and produced the following results: Fire Hazard Properties Spread of Flame Index 0 Smoke Development Index 3 Required Fire Safety Measures Based on the testing of the Euro Clad panel to AS/NZS 3837:1998 and AS :1999, the panel achieves a Group 3 rating, Spread of Flame Index of 0 and Smoke Development Index of 3. Evaluation Summary In the opinion of Ignis Solutions, the assessment has demonstrated that the Euro Clad panel can be used where Group 3 products are listed and therefore in these locations satisfies the requirements of BCA Performance Requirement CP2 (a)(i), (ii) and (iv) as well as CP4 through the Deemed-to-Satisfy Clause C1.10(ii). The Euro Clad Selekta Panel has been tested to the requirements of AS These results, as detailed above are less than the maximum values set by Clause 7 table 4.
