By creating a service void above the main floor slab, typically anywhere between 300 and 2000 mm deep, they offer valuable space for electrical, HVAC, and other building systems. But this convenient void can also bring challenges: installations within it may form a significant local fire load that designers must not overlook.
This is where the new White Paper comes in. Its motivation is straightforward: how does DELTABEAM® perform when part of the beam—especially the top flange—is exposed to fire within the raised floor void?
Over the past years, European research teams have investigated fire behaviour in raised floors with void depths below 600 mm. In controlled laboratory environments, experts conducted multiple fire tests, adjusting key variables that influence fire severity and duration. Their work led to an alternative fire curve—one demonstrably less conservative than the standard fire curve—yet more representative of realistic conditions.
Our new White Paper builds on that research. It takes a deeper look at the findings, interprets what they mean for practical design, and assesses how well DELTABEAM® performs under these proposed fire exposure scenarios.
If you’re working with raised floors, or simply curious about what happens inside that hidden space during a fire, this White Paper offers clear insights and a fresh perspective.
