The Terrecotta Army of Xi“an, in the Chinese province of Shaanxi, with over 7000 lifesize clay figures, is one of the most valuable art treasures in the world. It was discovered by accident in 1974 by Chinese farmers sinking a well and has been a UNESCO World Heritage site since 1987. The burial site of the first Chinese emperor Qin is now protected by Heated Glass, by Belgian firm Ceyssens with the product name IQGlass(R). This special glass with metal coating creates a source of warmth using electricity. Edgetech has supplied its Super Spacer(R) to the project, which ensures that the special glass is optimally sealed. The highly sensitive figures, only a quarter of which have so far been uncovered by the exceptionally difficult archaeological excavation, were left in place and the museum was simply built around the mausoleum. The metal coating distributes warmth evenly across the entire glass surface, and each individual element can be separately controlled. At the same time, a coating on the outer side ensures that the warmth is only directed towards the inside and the cold air outside does not get through. The combination of Super Spacer(R) and Heated Glass ensures thermal insulation values in normal gas-filled units of 0.8 W/m2k, thus ideal, say the two companies, where conventional heating has to be avoided or for complex roof glazing that not only has to insulate well but also warm the area sufficiently too.
