Abstract
The invention relates to a ballistic block (10) particularly for a bullet-resistant glazing (100) or as bullet-resistant glazing (100), wherein the ballistic block (10) comprises at least two transparent panes (11, 12, 13, 14) joined to one another via an interlayer (19), whereby the ballistic block (10) is constructed without an energy-absorbing layer or polycarbonate film, and whereby the at least two transparent panes (11, 12, 13, 14) and in particular all the transparent panes (11, 12, 13, 14) of the ballistic block (10) are each panes made of toughened glass.
Claims6
A ballistic block for a bullet-resistant glazing, wherein the ballistic block comprises
- at least two transparent panes joined to one another by an interlayer, wherein the interlayer is composed of at least partly or partially from an ionoplast polymer,
- a first side defined by one of the at least two transparent panes,
- a second side opposite the first side,
- wherein the second side is defined by another one of the at least two transparent panes,
- wherein the ballistic block does not include a further energy-absorbing layer on the first side,
- wherein ballistic block does not include any polycarbonate, and
- wherein the at least two transparent panes are each made of heat-strengthened glass having a flexural strength of 70 N/mm2 to 120 N/mm2,
- wherein the ballistic block does not include a hollow space between any of the at least two transparent panes from the first side to the second side, and
- wherein the at least two transparent panes are combined by the interlayer into one structurally self-supporting unit such that when the ballistic block is installed, the ballistic block is retained on no more than two sides of the ballistic block.
