General 
SOTERA has been engaged to carry out fire engineering assessment of the proposed performance 
solution for the project:  
Client: 
Delta Panels Pty Ltd  
Project Title: 
DeltaDualCore™ Panel Awning Systems 
This summary gives the proposed performance solution and BCA issues. The main body of the report 
provides the detailed documentary evidence justifying the performance solutions. To avoid errors in 
duplication material may not be repeated. The main body of the report must be read in conjunction with 
this summary. 
1.2 
Brief Description of Application 
This fire engineering report is intended to assess the generic application of DeltaDualCore™ panel awning 
systems when used as a Class 10a structure (awning or patio) attached or adjacent to a Class 1a building 
positioned within 900 mm of a site boundary pursuant to NCC 2022 Housing Provision Standard & Volume 2.    
1.3 
Fire Safety Systems 
(A)  Performance solution systems:  
1. 
This performance solution is solely applicable to the DeltaDualCore™ roofing system which may 
comprise either DeltaTrim™ or DeltaOrb™ dual core sandwich panels with a core consisting of 
Expanded Polystyrene with fire retardant (EPS-FR) and mineral wool composite (refer to 
Section 3), non-combustible supporting structure and non-combustible plumbing fixtures (gutters 
and downpipes).  
2. 
All components used in the awning and patio construction shall be compliant with Section 3. The 
components shall not be modified except with the written authorisation of the manufacturer and 
SOTERA.  
3. 
The following restrictions apply for the Class 10a awning and patio installation: 
(a) Two or more sides (making up at least one third of the awning or patio perimeter) shall 
be “open”; that is the roof covering shall be more than 500 mm from another building or 
allotment boundary on at least two sides without enclosing these sides with a wall, 
privacy screen or the like within 500mm of the edge of the roof covering. A boundary 
along a road or public space such as parklands, lakes, rivers and the like (where the 
construction of buildings is unlikely) may be considered open regardless of proximity to 
the boundary subject to no vertical obstruction (wall, privacy screen or the like) within 
500 mm of the edge of the roof covering. 
(b) The awning or patio structure shall not provide direct vertical support to any part of the 
adjacent Class 1 building. 
(c) The portion of the awning system which is located within 900 mm of a site boundary 
shall consist solely of non-combustible components (subject to (d)) including: 
(i) Mineral wool 
(ii) Pre-finished steel sheeting with combustible surface finish not exceeding 1 mm 
thickness and with a spread of flame index no greater than 0 in accordance 
with NCC H3D2(1)(e). 
(iii) Steel fixtures, gutters and the like 
(iv) Steel columns, beams, purlins and the like
