Lightweight domes are assembled in low time-frame and designed for concerts, celebrations or exhibitions – good acoustics and sound control, microclimate management as well as multiple options of design. Dome structures are designed to withstand high load hanged on the structure inside the dome, like the sound system, lighting, and decorations. Event domes usually are coated with PVC tent for hydro isolation. Transparent and heat-blocking tent types can be used optionally as parts of the whole coating system. The firmness of the dome structure and the thickness of the tent is selected by the geographical area to withstand the required loads like wind, rain, and snow. Several adjacent domes can be connected to create one complex designed for the special needs.
