Multi layered safe glass, called laminated, consist of two or more glasses connected to one another by layers of special resins – elastic and rupture resistant. This way if broken, the pieces keep together, reducing the risk of getting hurt and not permitting passage. Depending on the configuration – the number of the combined glasses and layers, in addition to the safety they are also different levels of protection against forced entry, penetration and shots. Almost any glasses can be laminated, and the connecting layer to be transparent, matt, coloured, with an image. Such a glass improves the noise insulation, stops the ultraviolet light and can be combined with other types of glasses and insulating glass units. As a disadvantage to the laminated glass we can consider his strength – it is equal to the strength of one glass of its composition. By using reinforced glasses this disadvantage can be eliminated fully.
