Abstract

A penetration resistant door light adapted to withstand impact from flying debris as might occur in a hurricane or other high-wind condition. The door light includes inner and outer frame halves that support a panel assembly within an opening formed in a door. The panel assembly includes a sheet or layer of transparent impact resistant material such as a polycarbonate or laminated glass. The impact resistant sheet is structurally secured to at least screws extend through all of the inner frame half, the impact resistant sheet, and the outer frame half. In an alternative embodiment, a structural adhesive intersecures the impact resistant sheet and the outer frame half.

Claims

1. A door light comprising:

an inner frame half;

an outer frame half;

a laminated glass assembly including a piece of glass and a sheet of transparent, impact resistant, resilient, polymeric material bonded to said piece of glass, said laminated glass assembly disposed between said inner and said outer frame halves; and

structural adhesive structurally intersecuring said outer frame half and said laminated glass assembly.

2. The door light of claim 1 further comprising a second piece of glass intersecured to said sheet of impact resistant material in a spaced insulating construction.

3. The door light of claim 1 wherein said impact resistant material is a polycarbonate.

4. The door light of claim 2, further comprising a third transparent sheet intersecured to said sheet of impact resistant material in a spaced insulating construction opposite said second transparent sheet.

5. The door light of claim 4 wherein each of said frame halves includes a plurality of mounting holes, and further comprising a plurality of mounting screws, each of said mounting screws extending through one of said mounting holes.

6. The door light of claim 1 wherein said impact resistant material is polybutylene having a thickness of at least about 0.092 inches.

7. A window comprising:

an outer frame half to be mounted within an opening formed in a supporting structure;

a laminated glass including a piece of glass and a transparent, impact resistant, resilient, polymeric sheet bonded to said piece of glass;

an inner frame half to be mounted within said opening in said support structure;

fastener means for intersecuring said inner and said outer frame halves; and

a structural adhesive adhesively and structurally securing said said laminated glass to said outer frame half.

8. The window of claim 7 wherein said impact resistant sheet is polybutylene having a thickness of at least about 0.092 inches.
