3.3 Thickness vs. Temperature & Span Guidelines
Based on heat flux of 8–10W/m², the following recommendations apply:
| Panel Thickness (mm) | Temp Difference (°C) | Max Wall Height (m) | Max Ceiling Height (m) | Applicable Temp Range (°C) |
|---|---|---|---|---|
| 50 | 30 | 3.5 | 2.4 | 25 to 0°C |
| 75 | 40 | 4.5 | 3.8 | 25 to -5°C |
| 100 | 50 | 5.0 | 4.5 | 25 to -10°C |
| 120 | 60 | 5.5 | 6.0 | 25 to -15°C |
| 150 | 70 | 6.0 | 6.5 | 25 to -25°C |
| 180 | 80 | 6.5 | 7.1 | 25 to -40°C |
| 200 | 90 | 7.0 | 7.6 | 25 to -55°C |
Note: Max heights apply under no wind load and internal/external pressure difference. Steel beams required for longer spans or wind loads.
