Sacura Group offers a wide range of bulletproof and burglarproof windows, the frames of which are made of steel, aluminium or wood.
The structure of the glass unit includes a multilayer protective glass or multifunctional glass Sacura Secure.
It is not necessary to dismantle windows in a functioning building to ensure bulletprofness. It is enough to install a bulletproof screen from inside the room (back glazed window system).
In addition, this solution increases thermal insulation and reduces noise.
Bullet resistance:
FB 2NS ÷ FB 7NS in accordance with the EN 1522:1999;
BR 2NS ÷ BR 7NS in accordance with the EN 1063:1999.
Burglary resistance:
RC2 ÷ RC4 in accordance with the EN 1627:2011.

NOTE 1: When a shot is to be fired at a single point the test range may be reduced to achieve the firing accuracy as defined in Section 6 of EN 1523:1998. In this case it may not be possible to measure the velocity of the bullet. NOTE 2: To be classified FB4 or FB6 the specimen shall be tested with both calibres listed. |
