One of the problems of ventilated facades systems is the emission of heat-insulating layer. Emission is a process of separation or removal of material’s particles from insulation by virtue of different factors. In this article research of emission of contemporary light weight insulation in system of hinged ventilated façade (VF) with various design is carried out. Impact of design and hydraulic factors on insulation destruction is estimated. Quantitative characteristic of blast air through rustication joints in a vertical channel is given and, consequently, it is possible to determine control point of recirculation zone formation – the beginning of turbulent air flow. Particle’s removal in insulation and decline of its properties are most probable in case of tangential stress, that conform to turbulent air flow.
