Based on the test results, it is clear that the paint and the adhesive do not significantly contribute to the fire 
hazard of the 100 mm thick DeltaCool™ panel. 
The paint and adhesive remain consistent between the DeltaCool™, DeltaSecretFix™, and DeltaTrim™ panels 
with only variations in the skin profile in each panel. Both the DeltaCool™ and DeltaSecretFix™ panels are flat 
with a negligible difference in the painted coating or the adhesive. The profiled skin of a DeltaTrim™ panel 
would have a greater surface area which means a greater area of the painted coating and the adhesive layer. 
The quantity of the painted coating or the adhesive layer by linear metre for the DeltaTrim™ panel is 
approximately increased by 7%. But as the tested sample has a nearly unrecognisable impact on the HRR, a 
minor variation of approximately 7% would not be expected to cause an impact on the HRR in the order of 
magnitude that would be required to achieve an HRR of 1 MW.

The proposed panelling systems to inherit the testing of the 100 mm thick DeltaCool™ panel with a mineral 
wool core are outlined in Table 4-1.
