ABSTRACT:
A transparent laminated window structure having high impact resistance is disclosed, wherein the window comprises a continuous inner layer of thermoplastic material, and an outer layer substantially parallel to the inner layer including at least a first course of discrete, mutually spaced glass segments, the spaces between adjacent segments containing an adhesive material. The window structure may further comprise a strip of elastomeric material compressed between the inner and outer layers so as to define a gas gap between the layers. A projectile contacting a particular glass segment in the outer layer will fracture that segment, but will not cause cracking in the adjacent, mutually spaced segments in the same course, and therefore, a high degree of visibility through the window structure will be retained after impact by the projectile.
