Laminated glazing, once limited to just the windshield, is finding more and more application in other positions on the vehicle due to its ability to improve passenger safety, security and comfort. Problems are encountered when producing a laminated version of a tempered part with holes, because tempered glass is 4 to 5 times stronger than annealed glass. The laminate of the invention has a hole in the exterior glass layer. An insert is bonded to a cutout in the area of the hole on the interior glass layer so as to reinforce the hole and distribute the load over a wider area. The result is a laminated glazing with one or more holes that has the reliability of and is a direct replacement for a tempered part.
