The rapid development of science and technology have contributed in the applied building design. One of them is the improvement of the construction design of the building envelope. Current high-rise building design impacts in wider building envelop surface area and greater heat load received from the sun irradiation. One of the common used design is the doubleskin façade type building envelope. The insulation characteristic given by the envelope interlayer gap can reduce the heat load received. However, in fire cases, the gap becomes hot gasses path, supporting wider flame propagation. Its position in the outside leads to harder fire suppression effort. During this time, the active fire protection system design has just considering fire scenarios inside the building. This research is conducted to see water droplets impact as extinguisher aspect on interlayer gap hot gasses propagation. The experiment used wooden layer with 540 mm x 80 mm x 6 mm dimention as the envelope layer. The interlayer gap varies among others 30 mm, 50 mm, and 70 mm to see flame output characteristic through and time needed for 4 nozzles to extinguish the flame. The suppression system applied is expected to be a solution in the case of double-skin façade building envelope fire event.
