A louvre arrangement 201, preferably for a window, in which the outer frame 202 has a rear drainage aperture 230 that provides a flow path for water through the bottom of the frame 232, for discharge into a glazing channel. The frame may have an integral drainage profile or baffle 220 for channelling water away from the louvre via the flow path. The profile may at least partially extend up sides of the frame, and may be on all sides of the frame. The louvre may also include blade support clips 204, and formations 216 for the attachment of a screen or guard 218. The device is intended to prevent rainwater from flowing back through the louvre frame during excessive weather conditions or high wind. In an alternative aspect, a louvre is provided with an outer frame having an integral drainage profile for directing water flow away from the frame. |
