Laminating a one-way vision interlayer in glass
See-through graphics are printed onto a clear polyester film to provide one-way vision, solar control, privacy and design options to enliven buildings. The film is then sandwiched between adhering interlayers before it is laminated between two glass panels. The product has been used for architectural projects around the world for over 15 years.
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.
