Step 3.3.1  Determine A
The length of A which is the Mineral Wool (MW) core component of Figure 6 - Panel Layout Drawing is set at 900mm. Both 
DeltaDualCore™-Trim & DeltaDualCore™-Orb are certified to span 900mm in all designed wind regions and patio styles 
when the core thickness is 75mm and above.
Step 3.3.2  Determine B
For Type 1/1P , Type 2 Type 3 & Type 4 structures, the length of B which is the Expanded Polystyrene Fire Retardant (EPS-
FR) core component of Figure 6 - Panel Layout Drawing is measured as the section from the Support Beam back to the 
attachment at the Existing House structure. In the case of a Type 0 Free Standing structure it is measured  to the support 
beam where the EPS-FR end of the panel will be fixed. The determination of the actual panel required based on the Wind 
Category and Structure Type can be assessed in the tables in Step 3 - Select the Style of Roof Sheeting.
Step 3.3.3  Determine C
The thickness of the panel required for C, which is the total length of the Insulated panel to be installed, is simply the 
thickness as determined in Step 3.2.2 - Determine B above, as the 900mm Mineral Wool end section is certified to span 
900mm for all Wind Categories and Structure Types for both DeltaDualCore™-Trim & DeltaDualCore™-Orb.
