“…One of the European routes to dealing with fire safety of wall claddings is testing fire performance of cavity barriers [11]. The new test method designated prEN 1364-6 [12] actually deals with all the applications where hidden fire spread is a safety risk: "Cavity barriers are provided within buildings to restrict the spread of smoke and fire in concealed spaces.…”

“…Therefore, Just et al [25] suggested a potential fire curve to test cavity barriers that consider the possibility of reignition. Moreover, Jensen [69] has cited that fire exposure could reach the hydrocarbon standard fire curve during cavity fire spread. Therefore, these concerns need to be further researched when testing the suitability of cavity barriers.…”

Fire spread scenarios associated with concealed cavity spaces have been relatively less discussed. The variation in studies with respect to geometry, influential parameters, and protection strategies has been an obstacle to deriving more generalized solutions in terms of cavity fire in buildings. A systematic literature review was conducted following the PRISMA method to identify the conclusive fire behaviour, safety risks, and protection strategies to enable future researchers to address cavity fire scenarios effectively, avoiding catastrophic disasters. This study identified that relative to open-fire scenarios, cavity fires could result in up to 10 times higher flame spread, up to 14 times higher heat exposure, and temperature conditions 13 times higher. Increased toxicity and smoke velocity are also found with cavity fires. Fire protection strategies and their efficiency were identified for a range of cavity geometries. Altogether, cavity spaces, especially narrow ones, cannot be neglected during fire safety, and proper risk identification is required to ensure the safety of the buildings and the occupants in a fire scenario.

“…These varying configurations have led to a series of issues regarding their hydrothermal, energy, sound and fire performance. 10 Construction details (eg, cladding fixings) 8 or fire barriers 11,12 may also affect flame spreading within the ventilation air cavity.…”

Summary During a fire event, ventilated facade systems may contribute to external fire spreading to the upper floors of a building via the facade, thus representing a significant risk. In this frame, the performance of a typical ventilated façade system under fire conditions is experimentally investigated, using a full‐scale compartment‐facade test rig. Two alternative façade configurations are examined and comparatively assessed, namely a plain façade (PF) and a ventilated façade (VF) system. Emphasis is given on the estimation of the thermal characteristics of the developed Externally Venting Flames (EVF) and the thermal boundary conditions developing on the façade's exposed surface. An extensive set of sensors was installed at the interior of the fire compartment, the façade systems and the exterior of the test configurations. Analysis of the experimental data suggests that even though gaseous combustion products managed to penetrate the air cavity of the VF system, no consistent flaming conditions were established. On the unexposed face of both PF and VF systems, temperatures remained constantly below 180°C throughout the duration of both fire tests. The Eurocode correlations are assessed against the obtained experimental data; certain parameters, such as EVF length, width and centreline temperature, are found to be under‐estimated by the Eurocode methodology.
