b'DeltaFireX TMCar Port System 3DeltaFireX TMCar Port System 3.1Description of Application This fire engineering report documents the assessment of the DeltaFireX TMcar port system when used as a Class 10a structure (car port) 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 DeltaFireX TMcar port system comprises: a)A sandwich panel roof system (shown in Figure 3-1 to Figure 3-5) consisting of steel top and bottom skin with a non-combustible mineral wool (MW) core. Perimeter encapsulation consists of steel flashing. b)Non-combustible support structure. c)Non-combustible plumbing fixtures (gutters and downpipes). The DeltaFireX TMcar port system incorporates a sandwich panel roof system with a non-combustible MW core and steel outer facings with a top skin consisting of 0.42 mm G550 AZ150 steel, and a bottom skin consisting of 0.55 mm G300 Z275 steelsee Figure 3-1.Delta Panels produce the DeltaFireX TMsandwich panel in two variations (see Figure 3-2), one with a trapezoidal upper facing (referred to as the DeltaTrim-MW system) and one with a corrugated upper facing (referred to as the DeltaOrb-MW system). The composition of the facing material for both the DeltaTrim-MW and DeltaOrb-MW 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-MW and DeltaTrim-MW panels. As such, the DeltaOrb-MW and DeltaTrim-MW 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 1-49'
