Use of the DeltaFireX Car Port System 
as a non-combustible roof covering. 
Based on the justification given in items 1 to 3 above, 
the DeltaTrim-MW and DeltaOrb-MW bonded laminate 
panels which make up the roof covering for the 
DeltaFireX Car Port System are suitable to be used as 
a non-combustible roof covering.

Conclusion and Compliance 
This fire engineering report confirms that the DeltaFireX car port system which may comprise of; 
• 
A roof system comprising either DeltaOrb-MW or DeltaTrim-MW panels complying with the 
specifications given in Sections C.1 and C.2 respectively,  
• 
A non-combustible support structure, 
• 
Non-combustible plumbing fixtures (gutters and downpipes), 
• 
Panel thickness ranging between 75 mm -150 mm, 
• 
Minimum cut length of 1800 mm,  
• 
Panel width of 1000 mm,  
• 
Top skin consisting of 0.42mm G550 AZ150 steel and bottom skin consisting of 0.55mm G300 Z275 
steel, 
Meets the performance requirements of H3P1(1) Volume 2, NCC 2022 when installed in accordance with the 
DeltaFireXRoof brochure version V15.10.21 and Section 4.4 of this report as a Class 10a structure (car port) 
attached or adjacent to a Class 1a building positioned directly adjacent to the site boundary (i.e. less than 900 
mm from the site boundary).   
The comparative assessment has demonstrated qualitatively that the DeltaFireX car port system (when 
installed to the requirements of Section 4.4) is equivalent to a non-combustible roof covering in accordance 
with the DtS provisions outlined within NCC H3D2 and does not increase the risk of fire spread between a 
Class 1 building and a neighbouring building over and above that permitted under the DtS provisions.  
Performance requirement H3P1(1) is satisfied. The assessment is compliant in accordance with 
A2G2(1)(b) and A2G2(2)(d).
