Abstract
Laminates comprising at least two glass plys surrounding at least one interlayer having at least one bore extending through the laminate are produced by excluding the interlayer from the area surrounding the bore(s) and positioning a load bearing insert around the bore. The insert may be positioned before or after the laminating process. The invention reduces the tendency for delamination around the area of the bore when the laminate is placed under load.
