Abstract

See full text

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″).
