Abstract: A glass panel mounting assembly (10) which comprises a laminated glass panel (11) which is resiliently deflectable, a U-shaped holder (12) in which one edge (16) of the panel (11) is rigidly mounted, and adjustable securing means (17) extending between the metal limbs (13, 14) of the holder (12) and below the panel edge (16) in order to clamp the panel edge between the metal limbs. A pair of packings (18) are arranged one between each side of the panel edge and the inner face of the respective adjacent limb of the holder, each packing being made of a hard plastics or elastomeric material having a slight degree of resilience, and sealant material (20) is arranged substantially to fill the remainder of the channel (15) which is defined between the free end of the limbs (13, 14) and the packings (18).
