3 DeltaFireXTM Car Port System 
3.1 
Description of Application 
This fire engineering report documents the assessment of the DeltaFireXTM car 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.  
3.2 
Description of System 
The DeltaFireXTM car 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 DeltaFireXTM car 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 steel – see Figure 3-1.  
Delta Panels produce the DeltaFireXTM sandwich 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.
