The disclosure includes multi-layered panels (10, 60, 204) including exterior layers of glass (12, 44) and interior layers of urethane (20, 36) and at least one layer of polycarbonate (16) between the urethane layers (20, 36) that result in enhanced shatter resistance within panels (10, 60, 204) tha
The disclosure includes multi-layered panels (10, 60, 204) including exterior layers of glass (12, 44) and interior layers of urethane (20, 36) and at least one layer of polycarbonate (16) between the urethane layers (20, 36) that result in enhanced shatter resistance within panels (10, 60, 204) that weigh between about 4.1 and 4.6 pounds per square foot. The panels (10, 60, 204) include an insertion tab (23, 61, 23″) of the polycarbonate layer (16) that enhances performance of the panel (10). Reinforced passageways (70, 200, 300), such as doors and windows of schools, hospitals and other public and private buildings, are disclosed using the multi-layered panels (10, 60, 204) with the insertion tab (23, 61, 23″).

1. A shatter-resistant, optically-transparent panel for resisting breaking of the panel into pieces, the panel comprising: a. a first layer being a first glass sheet having an exterior surface and an opposed interior surface, the first glass sheet having a thickness of about 3.048 millimeters;b. a second layer being a first urethane sheet having an upper surface secured adjacent the interior surface of the first glass sheet and having a lower surface, the first urethane sheet having a thickness of about 1.270 millimeters;c. a third layer being a first polycarbonate sheet having an upper surface secured adjacent the lower surface of the first urethane sheet and having a lower surface, the first polycarbonate sheet having a thickness of about 2.997 millimeters;d. a fourth layer being a second urethane sheet having an upper surface secured adjacent the lower surface of the first polycarbonate sheet and having a lower surface, the second urethane sheet having a thickness of about 0.381 millimeters;e. a fifth layer being a second polycarbonate sheet having an upper surface secured adjacent the lower surface of the second urethane sheet and having a lower surface, the second polycarbonate sheet having a thickness of about 0.762 millimeters;f. a sixth layer being a third urethane sheet having an upper surface secured adjacent the lower surface of the second polycarbonate sheet and having a lower surface, the third urethane sheet having a thickness of about 1.270 millimeters; and,g. a seventh layer being a second glass sheet having an interior surface secured adjacent the lower surface of the third urethane sheet and having an exterior surface, the second glass sheet having a thickness of about 3.048 millimeters; and,h. further comprising the first, second, third, fourth, sixth and seventh layers are configured to overlie and be coextensive with each other so that perimeter edges of the first, second, fourth, sixth and seventh layers overlie perimeter edges of adjacent layers to thereby define a common perimeter edge, and wherein the third layer being the first polycarbonate sheet overlies the adjacent second and fourth sheets and at least a portion of a perimeter edge of the third layer first polycarbonate sheet defines an insertion tab extending beyond the common perimeter edge defined by the first, second, fourth, fifth, sixth and seventh layers. 2. The shatter-resistant, optically-transparent panel of claim 1, wherein the entire perimeter edge of the third layer being the first polycarbonate sheet defines the insertion tab so that the insertion tab of the first polycarbonate sheet extends beyond all of the common perimeter edge defined by perimeter edges of the first, second, fourth, fifth, sixth and seventh layers.
