Laminated glass breaks faster than toughened glass does, but due to the presence of the PVB-film it is much harder to break completely. When the glass breaks, the laminated glass forms a star break, while toughened glass immediately falls apart into thousands of tiny pieces. Moreover, the laminated glass, unlike the toughened glass, can be sawed, cut or drilled. Furthermore, the PVB-film functions as a UV filter and protects the goods behind the glass from coloration. Laminated glass is also sound insulating and can provide optimal warmth-insulation in combination with double-glazing.
