| How does the fixing of services and lighting to a protected concrete soffit affect the fire performance of the concrete ? |
| |
| Drilling through the panels does not adversely affect the performance of the system, assuming of course that the installer does not go to far and drills holes everywhere. Tests have been carried out to both RWS and Hydrocarbon curves where services have been bolted through the PROMATECT® H ( simulated in the tests by suspending weights from expansion bolts ) and the performance of the system is consistent between these tests and the standard tests where no penetrations have been made. Of course, all services should be supported directly from the concrete and the installer should not rely on fixing any services only to the PROMATECT® H boards |
