Due to the continuous tightening of environmental, occupational safety, and health regulations, soundproofing must be given special attention in modern industrial facilities. For different reasons, soundproofing is equally important for studio buildings where external noise needs to be minimized to ensure uninterrupted work. Where large equipment needs to be moved in and out of soundproofed areas, doors, and gates with soundproofing capabilities close to the building walls are necessary. The design of soundproof systems must consider the properties of the noise source. High and low-frequency sound attenuation requires different structural designs. High-frequency sounds are dampened with lighter materials, while low-frequency sounds require heavier materials. Depending on the task, soundproof doors can be made with multi-layer special panel systems mounted on a steel frame or, for effective low-frequency absorption, even from cast-in-place reinforced concrete structures.

The rolling mass of soundproof doors can vary from 125 kg/m² to 750 kg/m². The movement of the heavy mass is ensured by high-capacity running gears on square steel guide rails embedded in the floor concrete. The wheels are made of extremely wear-resistant spheroidal graphite cast iron. The design of the upper guidance of the door is also a critical task. If the door separates the external from the internal space, it must safely transmit the forces from wind and possible impacts to the building’s structural system. Even doors installed inside the building must be engineered to counter the forces from air pressure differences.

Another task is to ensure the weather resistance of the facade door structures, which can be fully achieved with additional seals and deflection elements (canopy, water deflector, etc.).
