Conclusion and Compliance 
This fire engineering report confirms that the DeltaTrimTM DualCoreTM & DeltaOrbTMDualCoreTM panels which 
have; 
• 
A width of 1000 mm,  
• 
cut to length (1800 mm minimum),  
• 
thickness ranging from 75 mm -150 mm,  
• 
a core consisting of two parts including one part mineral wool (at least 900 mm in length and 
comprising the full width of panel measured from the edge of the panel) and remaining part fire 
retardant SL Grade Expanded Polystyrene (EPS), 
• 
top skin consisting of 0.45 mm Colorbond Steel and bottom skin consisting of 0.55 mm UniCote Steel, 
meet the performance requirements of H3P1(1) Volume 2, NCC 2022 when installed in accordance with the 
DeltaDualCore™ brochure version V27.08.21 and Section 4.4 of this report as a Class 10a structure (awning or 
patio) 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 and quantitatively that the DeltaDualCore™ 
system (when installed to the requirements of Section 4.4) does not increase the risk of fire spread from or 
to an associated Class 1 building when compared to the DtS base case.  
Performance requirement H3P1(1) is satisfied. The assessment is compliant in accordance with 
A2G2(1)(b) and A2G2(2)(d).
