Group number classification for the DeltaTrim-MW Panel only.  
The test was performed in accordance with the requirements of AS ISO 9705:2003 (R2016) to determine the group number that may be assigned to the material using the classification 
schemes given in AS 5637.1:2015.

NOTES:  
• 
Determinations based upon AS/NZS 4859 Parts 1&2:2018, Thermal insulation materials for buildings. 
• 
The Declared R-values are believed representative at the date of calculation, however the author reserves the right to revise calculations. 
• 
DeltaTrim™-MW roofs are 0.42&0.55mm metal-skinned insulated panels with a core of mineral wool of approximately 100kg/m3 density. 
• 
DeltaOrb™-MW roofs are 0.42&0.55mm metal-skinned insulated panels with a core of mineral wool of approximately 100kg/m3 density. 
• 
Total R values (roofs) calculated by adding air film resistances (0.04 outside, inside 0.11 winter, or 0.16 summer). 
• 
Thermal resistances calculated above are based on the following BRANZ test report of 10 samples each: 
• 
DI13193-001-01 of 24/8/2020 on 100 kg/m3 mineral wool panel, 100mm thick, λ50/90=0.0365 W/mK at 23°C. 
• 
Testing of 200mm product is pending so this report assumes the same thermal conductivity as for 100mm product. 
• 
Each R varies with insulation mean temperature and is calculated per Table 1 parameters of AS/NZS 4859.2:2018.
