Glass sliding windbreak system, design for the enclosure of external spaces. It comes with an embedded flower-pot, which fastens the device on the floor – i.e. it does not require permanent fixing. The system bears wheels to facilitate its removal from the area. Alternatively, the iron box can be covered with a lid and allowing for the device to be used as seating. It is operated manually: By lowering the upper glass-board, the horizontal counterweight is lifted, freeing up half the area of the opening. Dimensions are dependent on the project’s demands, with maximum allowable size 3m in width and 2,2m in height.
