Abstract
A glazing of high strength for a transparent marine window, architectural glazing or vehicle window in ground or air transportation includes at least an outer high strength glass ply and an inner high strength glass ply in a laminate, and a layered functional block arranged and integrated between the outer and inner high strength glass plies in the laminate. The layered functional block or a layered solar protection can include at least one annealed glass pane.

Glazing of high strength, comprising:
- at least an outer glass ply and an inner glass ply in a laminate, wherein each of the outer glass ply and the inner glass ply has a strength at breakage ranging from ca. 160-400 MPa and a short term allowable mechanical stress of ca. 40-100 MPa;
- and
- a layered functional block arranged and integrated between the outer and inner glass plies in the laminate, wherein the layered functional block comprises
- an outer adhesive layer on the outer glass ply;
- an inner adhesive layer on the inner glass ply;
- at least one thin films system having the following layered sequence:
- a sputtered or deposited top protecting interference layer;
- a sputtered or deposited blocker layer;
- a sputtered or deposited silver coating or layer;
- a sputtered or deposited seed layer;
- and
- a sputtered or deposited interference base layer;
- and
- at least one annealed glass pane having a strength at breakage ranging from ca. 40-70 MPa and a short term allowable mechanical stress of ca. 10 to 18 MPa,
- wherein the at least one thin films system is provided on the annealed glass pane.

Method of producing a high strength glazing for a marine window, the method comprising:
- providing at least an outer glass ply, an inner glass ply, and a layered functional block;
- arranging the layered functional block between the outer and inner glass plies to obtain a pre-glazing stack;
- and then
- treating the pre-glazing stack in an autoclave to laminate the pre-glazing stack in order to obtain the glazing, wherein the glazing comprises:
- at least the outer glass ply and the inner glass ply in a laminate, wherein each of the outer glass ply and the inner glass ply has a strength at breakage ranging from ca. 160-400 MPa and a short term allowable mechanical stress of ca. 40-100 MPa;
- and
- the layered functional block arranged and integrated between the outer and inner glass plies in the laminate, wherein the layered functional block comprises
- an outer adhesive layer on the outer glass ply;
- an inner adhesive layer on the inner glass ply;
- at least one thin films system having the following layered sequence:
- a sputtered or deposited top protecting interference layer;
- a sputtered or deposited blocker layer;
- a sputtered or deposited silver coating or layer;
- a sputtered or deposited seed layer;
- and
- a sputtered or deposited interference base layer;
- and
- at least one annealed glass pane having a strength at breakage ranging from ca. 40-70 MPa and a short term allowable mechanical stress of ca. 10 to 18 MPa,
- wherein the at least one thin films system is provided on the annealed glass pane.
