Port Praski is an area of ​​buildings being built in the center of Warsaw. Its construction began with the residential part, the architecture of which refers to the historical architecture of the capital. Next to the residential district, there will be the service and commercial Doki, business City and recreational Media Park. The investment will be complemented by extensive green areas, which will be conducive to relaxation for all Warsaw residents. In one of the service facilities there is the Zdrowa Krowa restaurant, in which we responded to the problem of penetrating, bothersome odors. With the help of AEROSEAL® technology, tightness tests and sealing of channels were carried out. As a result, the ventilation ducts meet the standards of tightness class B.
