Dock shelters are installed on buildings’ façades. They seal off vehicles at loading bays. Dock shelters reduce heat loss during colder seasons and heat inflow during summer, prevent insects from entering the facility, improve comfort of work for the personnel and lower running costs of the facility. Side flaps are made of plastic material with increased side stability, which guarantees high flexibility as the vehicle presses the loading bay during docking. Upper flap, on the other hand, has higher tear strength (1100 N).
