An opaque cladding panel for incorporation in a fully-glazed facade of a building comprises an outer glass sheet (1) which is separated from an opaque backing sheet (4) by a peripheral spacer (3), there being provided at least one venting aperture (12) to ventilate the interspace between the glass sheet (1) and the opaque backing sheet (4). The glass sheet (1) is optionally coated on its inner surface with a coating (2), such as a semi-reflective coating. The provision of the at least one venting aperture (12) ventilates the interspace and thereby reduces or avoids condensation in the interspace which would degrade the coating (2) on the glass sheet (1). |
