Manufactured using metal facings bonded to a high density structural mineral wool core, FireWall panels offer exceptional spanning characteristics.
FireWall’s panel strength characteristics have been calculated following the European recommendations for Sandwich Panels: TWG 7.4.ECCS W56; including a load safety factor of 1.5 and material safety factor of 1.25.
| Product | Panel thickness (mm) | |||||
| 75 | 100 | 125 | 150 | 175 | 200 | |
| FireWall | 6.55 | 7.98 | 9.31 | 10.54 | 11.2 | 12 |
| FireWall Extra | 6.7 | 8.14 | 9.47 | 10.73 | 11.4 | 12 |
Wall panel calculations are based on a uniformly distributed load of 0.25 KN/m2.
Please note the above spans are based on the cold state structural performance of the panels.
Where fire resistance is required the allowable spans may need to be reduced to ensure the
fire resistance is maintained, these allowable spans are shown in the section on Fire Performance.
