The company "Ligęza" has been producing anti – burglary glass for over 20 years and was actually the first company to offer this type of glass in Poland. All kinds of bulletproof glass have valid certificates issued by IMP (Institute of Precision Mechanics) in Warsaw, and are subject to rigorous assessment at every stage of production, by the Factory Quality Control staff.

The bulletproof glass is permanently marked in accordance with the requirements of EN 1063. Description label is placed between the glass layers, which prevents removal of the marking.

A very important issue is the correct installation of the bulletproof glass in suitable frames which must be of proper strength and endurance. Traditional frames made of wood or PVC do not have sufficient strength. Our company offers bulleproof glass assembled in specially designed steel frames.

Please note that the bulletproof glass can easily be damaged. Smashing the surface of glass with a metal object with sufficient force causes the outer layer of glass to crack. However, such breakage causes neither significant damage to the glass nor deterioration of the mechanical properties of the glass.

Bulletproof glass offered by our company is both anti-burglary and bulletproof glass. This means that e.g. antiburglary glass class P6B is as well bulletproof in class BR1"NS", class P7B is as well bulletproof in class BR2"S",and anti-burglary glass class P8B is bulletproof in class BR3"S".

Our double function glass, that combines bullet-resistant and anti-burglary feature, which is unique advantage, is called in our company as follows: P6B/BR1"NS", P7B/BR2"S" and P8B/BR3"S". The bulletproof glass in class BR5 "S" has not been certified against burglary.

You can make the bulletproof windows transparent, matt and Venetian mirror effect. The latter two are formed only by adding a further layer of glass, usually having a thickness of 4 mm. Bullet-proof windows can be combined in complex packages. The maximum size of bulletproof glass in the standard version can be 3210x2250mm, while it is possible to perform full-glass pane "Jumbo" and so 6000x3210mm. Projects above standard size are treated as special, and require each individual arrangements - please contact our sales office. It does not specify a minimum size windows burglary, but for practical reasons it is not carried out windows smaller than, for example 300x300mm, although this is possible. The table below summarizes the bulletproof glass classes offered by our company.
