A method for making a laminated glazing panel is described. A bolt having a head portion and a stem portion extending therefrom is positioned in a hole in a sheet of glazing material so that a first surface of the head portion is faces in the direction of a first major surface of the sheet of glazing material and the stem portion extends beyond a second major surface of the sheet of glazing material. A sheet of adhesive interlayer material is positioned on the first major surface of the sheet of glazing material to cover the first surface of the head portion. Suitable lamination conditions are used to laminate the sheet of adhesive interlayer material to the sheet of glazing material. During lamination, fluid trapped between the first surface of the head portion and the sheet of adhesive interlayer material is removed via a fluid pathway associated with the stem portion. Laminated glazing panels made using the method are also described.

Method for making a laminated glazing panel

A laminated glazing panel comprising first and second sheets of glazing material joined by an interlayer structure comprising a first sheet of adhesive interlayer material is described. Inboard of a peripheral edge of the first sheet of glazing material, the first sheet of glazing material has a hole therein. The laminated glazing panel further comprises a glazing fitting secured thereto, the glazing fitting comprising a head portion and an attachment feature. The head portion is positioned in the hole such that a first surface thereof faces the first sheet of adhesive interlayer material. Some of the first sheet of adhesive interlayer material is in the hole and is operatively associated with the first attachment feature thereby attaching the glazing fitting to the first sheet of adhesive interlayer material. Suitable glazing fittings and methods of making such laminated glazing panels are also described.
