b'DeltaDualCore Panel Awning Systems 3DeltaDualCore System 3.1Description of Application This fire engineering report documents the assessment of DeltaDualCore panel awning and patio systems when used as a Class 10a structure (awning or patio) attached or adjacent to a Class 1a building positioned directly adjacent to the site boundary pursuant to NCC 2022 Housing Provisions Standard & Volume 2 and installed to the requirements of Section 4.4.3.2Description of System The DeltaDualCore roofing system comprises: a)A sandwich panel roof system (refer to Figure 3-2, Figure 3-4 to Figure 3-5) b)Non-combustible support structure c)Non-combustible plumbing fixtures (gutters and downpipes) The DeltaDualCore sandwich panel roof system comprises steel outer facings (0.45 mm Colorbond steel upper facing and 0.55 mm UniCote Steel lower facingsee Figure 3-1) with a composite core containing EPS-FR and mineral wool as shown in Figure 3-1 (i.e. the patented DeltaDualCore composite panel). The core comprises separate parts mineral wool and EPS-FR bonded together along a stepped seam as shown in Figure 3-2. The mineral wool component shall have a minimum length of 900 mm as shown in Figure 3-2.Delta Panels produce the DeltaDualCore panel in two variations (see Figure 3-3), one with a trapezoidal upper facing (referred to as the DeltaTrim system) and one with a corrugated upper facing (referred to as the DeltaOrb system). The composition of the facing material for both the DeltaTrim and DeltaOrb systems are identical, it is only the profile of the upper facing that is varied. Based on the assessment provided in Section 3.3.2, the profile of the upper facing does not have any significant effect on the achieved fire performance of the DeltaOrb and DeltaTrim panels. As such, the DeltaOrb and DeltaTrim panels may be used interchangeably and the outcomes of this assessment remain applicable to both panel types. Material specifications as given by Delta Panels is quoted in Table 3-1. Revision 1-1113'
