A penetration resistant window includes a penetration resistant layer sandwiched between exterior and interior transparent sheets. The perimeter of the penetration resistant layer extends from the perimeters of the exterior and interior transparent sheets in a direction plane parallel with the planes of the transparent sheets. This extension allows the laminated window sheets to be mounted in a window frame such that the perimeter of the penetration resistant layer is secured within a channel in the frame, preferably by an adhesive such as silicone glue. The penetration resistant window is useful in architectural, residential and institutional applications for resisting debris penetration during hurricanes.
