Contra Vision Printed Interlayer

Contra Vision® Printed Interlayers™

Contra Vision® Printed Interlayers™ for laminated glass are suitable for architectural applications requiring the highest durability and performance. The graphics are printed as a dot pattern onto a clear polyester film using our patented Contra Vision® XR™ technology. All that can be seen from the inside is a pattern of tiny black dots which are hardly noticeable.

The secret of Contra Vision is being able to print two or more layers of dots in exact registration, without any overlap in the colours. The size and density of the dot patterns can be varied to achieve the desired level of transparency. A wide range of colours is possible including metalics and multiple colours can be incorporated to achieve complex graphics and images.

Key product details:

  • used worldwide on building projects for 15 years
  • see-through graphics printed as dot patterns with 40-50% transparency (see below)
  • conforms to safety glazing requirements
  • a range of thicknesses starting at 9.5mm (2x4mm panels)
  • maximum sheet width of 1.5metre
  • 99.5% UV blocking protects against colour fading

How it is made

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.

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.
