Security Glass

Security glass was invented to provide maximum protection against deliberate attack. The security glass was designed to protect people and their property against vandalism or thieves.

Glass panels may protect against any impact, falling objects as well as noise and fire. The security glass is considered to be safe, if its production method or combining processes allow to limit damages caused by hits, deformations or fire.

The safety glass is produced by combining two or more sheets of glass panes with a special film. This kind of glass does not break apart when broken down, and at the point of impact it has just cracks. Using the right type of film you can make anti-burglary and bullet-proof glass.

The production technologies of the security glass require using special PVB (polyvinyl butyral) with a nominal thickness of 0.38 mm between several layers of glass. The effectiveness of glass depends on a number of applied layers of the film. The glass panels may replace bars, shutters and blinds allowing to keep an aesthetic appearance of buildings. Glass with increased resistance to burglary is much more resistant to any impacts or cuts done with sharp objects.
