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.

Abstract: A filler composition consists of 60 to 85% by weight of silica, dolomite and/or calcite of size below 150 .mu.m and of average size above 20 .mu.m, and 40 to 15% by weight of an aqueous emulsion of 40 to 70% solids of a resin binder mixture comprising a quick drying polymer emulsion having a minimum film forming temperature above 5.degree. C. and a flexible polymer emulsion having a minimum film forming temperature below 5.degree. C., the polymer in the emulsion of minimum film forming temperature above 5.degree. C. constituting 60 to 90% by weight of the total polymer in the emulsions.
