Bulletproof and bulglary structures

Bulletproof and burglary structures

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.

*    To achieve the values for (5,56 X 45), the recommended barrel twist length = (178±10) mm

**   To achieve the stated values for Class FB 7, the recommended barrel  twist length = (254±10) mm 

       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.
