ABSTRACT:
A double glazing arrangement has at least one pane mounted between two opposed vertical channels and arranged for both vertical sliding movement within the confines of the channels without the provision of a counterbalancing system and movement in at least one lateral direction for removal of the pane without any initial dismantling of the arrangement. Releasable catches are provided which are for both holding the pane in a plurality of raised positions and preventing lateral movement of the pane. The arrangement is particularly advantageous for a pane of transparent acrylic material.
