OFFER / PRODUCTS / Antiburglary glass
Anti – burglary glass is composed of many layers of glass glued in lamination proces. All glass is made in accordance with European norm EN 356. The glass test according to this norm depends on cutting a hole in the glass with an axe of weight 2 kg. For example , to achieve lowest level of safety according to this norm glass must withstand 30 hits of axe to cut out specified size square hole.
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 anti-bulglary glass have valid certificates issued by ICiMB (Institute of Ceramics and Building Materials) in Krakow, and are subject to rigorous assessment at every stage of production, by the Factory Quality Control staff.
The anti – burglary glass is permanently marked in accordance with the requirements of EN 356 . Discription label is placed between the glass layers, which prevents removal of the marking.
A very important issue is the correct installation of the anti- burglarglass 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 anti-burglary glass assembled in specially designed steel frames.
Please note that the anti-burglary 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 nither significant damage to the glass nor deterioration of the mechanical properties of the glass.
Anti-burglary glass offered by our company is both anti-burglary and bullet-resistent glass. This means that e.g. anti-bulglary glass class P6B is as well bullet-resistant in class BR1"NS", class P7B is as well bullet-resistant in class BR2"S", and anti-bulglary glass class P8B is bullet-resistant in class BR3"S".
