Laminated glass is a security glass composed of two or more lairs of glass kept together by several lairs of Polyvinyl butyral (PVB) or resin.

In case of breakage, when the impact is not strong enough to go thru the glass, we see the effect “spider web”.
This type of security glass is used in locations where it is important in case of breakage to keep all glass chippings together until the whole glass is replaced.
