Contra Vision graphics are printed onto a clear polyester film which is sandwiched between an adhesive (PVB or EVA) and then glass on either side. The construction is then heated to laminate the pieces together, creating laminated glass.
Laminated glass provides added safety where impact is a risk (the glass is held in place by the Interlayer if it breaks) and is used in many situations including curtain walling, windows and skylight glazing.
An additional property of laminated glass for windows is that a PVB and EVA Interlayer can block up to 99.9% of UV radiation.
Laminated glass is also used to increase the sound insulation rating of a window, where it significantly improves sound attenuation compared to unlaminated glass panes of the same thickness.
