WHAT IS CLAIMED IS:

1. A light weight hurricane-resistant laminated pane comprising:

a first sheet of thermally strengthened glass having a thickness in the range of from 2 to 24mm;

a second sheet of chemically strengthened glass having a thickness in the range of from 0.3 to 1mm and a surface compression of at least 100MPa; and

a polymer interlayer between the first sheet and the second sheet and adhered to the first sheet and the second sheet.

2. The laminated pane according to claim 1 , wherein the first sheet is a sheet of a soda lime silicate glass.

3. The laminated pane according to any of the preceding claims, wherein the second sheet is a sheet of a soda lime silicate glass.

4. The laminated pane according to any of the preceding claims, wherein the second sheet is a sheet of a boro-aluminosilicate glass.

5. The laminated pane according to any of the preceding claims, wherein the second sheet is a sheet of an alkaline earth boro-aluminosilicate glass.

6. The laminated pane according to any of the preceding claims, wherein the second sheet has a thickness in the range from 0.85 to 0.4mm.

7. The laminated pane according to any of the preceding claims, wherein the second sheet has a thickness in the range from 0.8 to 0.45mm.

8. A window comprising a laminated pane according to any of the preceding claims.

9. A process for forming a hurricane resistant laminated pane, the process comprising:

thermally strengthening a first sheet of glass having a thickness in the range of from 2 to 24mm;

using a polymer interlayer, laminating the first sheet of glass with a second sheet of chemically tempered glass having a thickness in the range of from 0.3 to 1 mm and a surface compression of at least 100 MPa.

10. A hurricane resistant window comprising:

an outer pane having a thickness in the range of from 2 to 24mm;

an inner laminated pane comprising

a first sheet of thermally strengthened glass having a thickness in the range of from 2 to 24mm and

a second sheet of chemically tempered glass having a thickness in the range of from 0.3 to 1 mm and a surface compression of at least 100 MPa and a polymer interlayer between the first sheet and the second sheet and adhered to the first sheet and the second sheet.

11. The hurricane resistant window of claim 10 in which the first sheet of the laminated pane faces the outer pane.

12. The hurricane resistant window of claim 10 in which the second sheet of the laminated pane faces the outer pane.
