For applications that demand high safety standards the BSH20 series of glass blocks have been created, with a high mechanical resistance to the impact of bullets.
The BSH20 blocks are certified as bullet proof in class FB4 according to regulations DIN 52290-2 and EN 1522, and for this reason they are frequently used in "sensitive areas" such as cash dispensers in banks or prisons, and in all places where apart from the strength of the reinforced grid between the blocks, there must also be the certified strength of the glass blocks themselves.
The glass blocks belonging to this family are available in smooth and wavy glass designs and with three finishings (transparent, sand blasted on 1 side or 2 sides) as well as the Orsa glass design with a transparent finishing.
