A laminated glass pane having at least one rigid glass sheet and one flexible plastic material sheet is described, which has a peripheral strip disposed over at least a part of the edge of the pane over at least one edge of a flexible plastic sheet. The peripheral strip has two layers of respectively different materials, a first layer designated the “internal layer”, is comprised of a material having a softening temperature which is less than or equal to the temperature employed in autoclaving the sheets which are components of the pane, and a second layer designated the “external layer”, is comprised of a material having a softening temperature which is greater than the temperature employed in autoclaving the sheets.
