Assessment of the Delta MW and EPS-FR Roof System Against the Applicable DtS 
Configurations 
Figure 4-11 to Figure 4-13 indicates the dominant mechanisms for fire spread to the site boundary for the 
Delta MW and EPS-FR roof system when attached to a Class 1 building and positioned within 900mm of a 
site boundary in comparison to the DtS base case for each of the three fire scenarios.
