b'Delta MW and EPS-FR Panel Awning and Patio Roof System 3Delta MW and EPS-FR Awning and Patio Roof System 3.1Description of Application This fire engineering report documents the assessment of the Delta MW and EPS-FR panel awning and patio system when used as a Class 10a structure (awning or patio) attached or adjacent to a Class 1a building positioned less than 900 mm from 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 Delta MW and EPS-FR roofing system comprises: a)A sandwich panel roof system (Figure 3-1 to Figure 3-4) with 1 x Panel Type I (see located adjacent to and parallel with the allotment boundary, and any number of Panel Type II located more than 900 mm away from the site boundary. b)Non-combustible support structure c)Non-combustible plumbing fixtures (gutters and downpipes) The Delta MW and EPS-FR sandwich panel roof system comprises two sandwich panel types: 1.Panel Type IMW core sandwiched between steel outer facings (0.42mm G550 AZ150 steel upper facing and 0.55 mm G300 Z275 Steel lower facingsee Figure 3-1) with a minimum panel width of 900 mm. 2.Panel Type IIEPS-FR core sandwiched between steel outer facings (0.42mm G550 AZ150 steel upper facing and 0.60 mm G300 Z275 Steel lower facingsee Figure 3-1). Delta Panels produce each of the panel types (Panel Type I and Panel Type II) in two variations (see Figure 3-2), 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 fire performance and response to fire for DeltaOrb and DeltaTrim panels. As such, the DeltaOrb and DeltaTrim systems may be used interchangeably for Panel Type I and Panel Type II. Material specifications as given by Delta Panels is quoted in Table 3-1. Revision 1-410'
