Abstract
A penetration resistant window includes a sheet of window glass having a penetration resistant layer adhered thereto. A floating sheet made of hard material such as glass is adhered to the penetration resistant layer in order to provide abrasion resistance. The perimeter of the floating sheet is set back from the perimeter of the window glass. This set back allows the window to be mounted in a window or door frame such that the perimeter of the window glass is secured to the frame, but the floating sheet is unconstrained by the frame. The penetration resistant window is useful in architectural, residential and institutional applications for resisting debris penetration during hurricanes.
Claims13
A penetration resistant architectural window comprising:
- a frame;
- window glass constrained within the frame;
- a penetration resistant sheet substantially co-extensive with the window glass and constrained within the frame, wherein the window glass and penetration resistant sheet have substantially the same periphery;
- and
- a floating sheet supported on the penetration resistant sheet and substantially unconstrained by the frame, wherein the penetration resistant sheet remains substantially intact after the window glass is broken and the window is subjected to a repeated cycling of inward and outward pressures applied against the penetration resistant sheet.
