Abstract: The invention relates to a slat (1) or a slatted roof (20) or a slatted window, comprising a light-permeable sheet-like covering element (2) having a longitudinal extent and width (b), wherein the width (b) is less than the longitudinal extent, and having an axis of rotation (5) which runs along the longitudinal extent of the slat (1) in order to pivot the slat (1) between a closed position and an open position.

Abstract: The invention relates to a slat (1) or a slatted roof (20) or a slatted window, comprising a light-permeable sheet-like covering element (2) having a longitudinal extent and width (b), wherein the width (b) is less than the or extent, and having an axis of rotation (5) which runs along the longitudinal extent of the slat (1) in order to pivot the slat (1) between a closed position and an open position, in order to allow a particularly flexible variation of the incoming sunlight entering a room (22) situated below the slatted roof (20) and in order to be able to set the desired temperature, climate control and brightness conditions in the room in a targeted manner, it is proposed that the slat (1) has at least one light-impermeable sheet-like shading element (6) having a longitudinal extent and a width (h), in which the shading element extends with the longitudinal extent thereof along the longitudinal extent of the covering element (2), that it is arranged with a first longitudinal side (6a) on the covering e

Abstract: A face mounting infilling system for walls and linings of buildings. The infilling elements are designed at their ends in such a way that they may be clamped to the upper edges of lower linking units, which in turn are designed in such a way that upper linking units may be snap-locked thereon.
