The invention relates to entirely transparent sliding screens (3) and (4), which do not have a frame around any of the periphery thereof, so to allow improved visibility. The screens slide inside guides (14) and (15) provided at both ends of a fixed screen or frame (1). The screens (3) and (4) can be stopped at the desired height according to wind control requirements, the upper screen (3) by means of a tubular motor (9) and the lower screen (4) manually. The tubular motor (9) is housed in the intermediate lower portion of the system, which takes the form of a hatch (32) that houses both the shaft into which the tubular motor (9) is inserted and a sealed channel and strip (11) where the electrical connections are joined. |
