A composite mirror panel comprises a front flexible vitreous sheet 1 whose rear face is provided with a reflective coating 2 to form a mirror 3. A flexible waterproof backing sheet 5 is watertightly bonded at 4 to the rear of the mirror 3 to form a laminate 6. A corrugated backing sheet 8 is bonded to the first backing sheet 5 along crests 9 of the corrugations to form a composite mirror panel which is flexible about axes parallel with the corrugations. The first backing sheet 5 may be of vitreouus material thicker than the mirror sheet 1 or it may be a metal sheet. |
