“…Nevertheless, the high cost of large-scale fire tests and the strong influence of scale effect have limited the deeper understanding of EPS ETICS fire research. Fire characteristics of a single component have been reported, such as EPS [7][8][9][10], adhesive [11], polymer-modified concrete [12,13], and finishing coat reaction-to-fire performance [14,15]. However, it is not sufficient to use the reaction-to-fire performance of a single component to evaluate fire hazards of any façade system [16].…”

The expanded polystyrene (EPS) façade has been widely used to save building energy, but it has also caused many severe facade fire accidents worldwide. Especially for aged buildings, the naturally weathered exterior surface layer can further increase the facade fire risk and the fire spread rate (FSR). In this work, a series of real-scale EPS External Thermal Insulation Composite System (ETICS) façades are tested via the JIS A 1310 standard. The EPS thickness varies from 100 mm to 300 mm, density changes from 15 kg/m 3 to 30 kg/m 3 , and heat release rate (HRR) of window spilled flame ranges from 600 kW to 1,100 kW. Tests showed that the surface cement layer was quickly damaged by a spilled flame that provided negligible fire resistance for the internal flammable EPS panel. The measured upward FSR increases with the rising of HRR and with the decreasing EPS thickness like the thermally thin material. An empirical correlation of instantaneous upward FRS is proposed, FSR= 0.22Φ + 3.45 [cm/min], where Φ is a modified fire propagation index derived from the experimental temperature distribution. In addition, a simple prediction method for FSR is proposed for the façade fire and verified by the experimental data. This work provides a useful method to quantify the upward façade fire propagation, which also helps evaluate the fire risk and hazard of EPS ETICS façade prior to the costly large-scale tests and installation.

“…Various research on ETICSs is focused on the probability of fire spread, fire safety, and fire barrier influence on ETICS reaction to fire performance. However, little knowledge is available on influence surface preparation mortar, reinforcing mesh, EPS thickness, and other treatment on the ETICS reactionto-fire performance [11][12][13][14][15][16].…”

Properties of External Insulation Surface Preparation Mortar Using Expandable Graphite for Fire Resistance

et al. 2019

In the case of fire, surface treatment agents used in external insulation finishing methods are substances that are vulnerable to fire. This study examined the incorporation and applicability of expandable graphite in surface preparation mortar so that heat transfer to the surface part can be suppressed even when the cementitious surface preparation mortar is thinly constructed in the external insulation method. Experimental results showed that the mechanical properties of surface preparation mortar were improved by using the fly ash and silica fume. Surface treatment materials using expanded graphite have a characteristic of expanding when a fire occurs. It was experimentally confirmed that incorporating expanded graphite can reduce the phenomenon of heat penetration to the rear surface when the surface preparation mortar is exposed to high temperatures such as a flame.

“…EPS ETICS consist of adhesive, EPS insulation material, cement, reinforcing mesh, and finishing coat. However, most current research has concentrated on the characteristics of single component reaction-to-fire performance, such as EPS reaction-to-fire performance, [3][4][5] adhesive reaction-to-fire performance, 6 polymer-modified concrete, 7,8 and finishing coat reaction-to-fire performance. 9,10 Furthermore, it has been widely acknowledged that performance of facade cladding systems in case of a fire cannot be fully assessed by laboratory tests.…”

Effects of opening edge treatment and EPS thickness on EPS external thermal insulation composite systems (ETICS) façade reaction‐to‐fire performance based on JIS A1310 standard façade fire test method

et al. 2017

External thermal insulation composite systems (ETICS) are quite common in constructions. However, the combustible insulation core induces serious fire disasters, especially considering thermoplastic expanded polystyrene (EPS) has been widely used as insulation core. Most of EPS ETICS building fire is caused by window spreading fire. The window opening edge treatment plays an important role in EPS ETICS fire prevention. Presently, in order to investigate optimal opening edge treatment and EPS thickness effects on EPS ETICS reaction‐to‐fire performance, façade fire tests based on JIS A 1310 standard façade fire test method were carried out by testing a series of EPS ETICS specimens varying EPS thickness, opening edge treatment methods and heating intensity. It is found that back‐wrapping is a good opening edge treatment method. When the EPS ETICS specimen is treated by back‐wrapping opening edge treatment method, the peak temperature, EPS burn area, time (20 minutes) averaged temperature, and heat flux density become low. The time (20 minutes) averaged temperature of each position from T1 to T5 versus EPS thickness is linear at heating intensity 300 or 600 kW. The averaged ratio of EPS burn area above opening (Sa) and below opening (Sb) is approaching 3.058.
