The invention relates to a windbreak system formed by: a set of independent panels that can be controlled individually, by moving the same longitudinally along an upper rail and a lower rail: and a folding door at one of the ends. Each panel and door comprises a rotation shaft and a folding shaft. The panels are moved manually, without bearing on rollers, and the entire weight of the panels rest on two strips of self-lubricating polymers that are inserted into two slots in the lower rail. The upper and lower rails are identical and have a rectangular cross-section and the panels are made from glass.
