A neutral appearance as well as a lower angular dependence of the reflection colour are the two most important innovations introduced by arcon with the sunbelt A51 coating. The latest addition to the range of solar shading products also scores points with its low external and internal reflection values as well as excellent thermal insulation.
With the new sunbelt A51 coating, arcon, one of the leading European glass refiners, is expanding its product range in the field of sun protection. Thanks to a new coating system, the developers at the company based in Feuchtwangen, Germany, have managed to achieve a more neutral appearance compared to the sunbelt A50 alternative. "This is primarily in response to a request from our customers in Europe and the US," says Simon Potts, plant manager for coatings at arcon.
What are the values of the A50 coating?
All technical data of the new coating are largely the same as those of the sunbelt A50 coating. A light transmission of 52 per cent lets pleasant sunlight into the interior and ensures well-being and comfort - even when the sky is overcast. The low light reflection from the inside of eleven per cent allows a pleasant view to the outside. In addition, the angle dependence of the reflection colour has also been improved. This ensures a more homogeneous perception of the glass surface from every viewing angle.
The highly selective coating with a g-value of 28 percent helps to reduce the cooling loads of buildings. "Under certain circumstances, no cooling system is required at all," explains Hermann Dehner, Product Manager at arcon.
Low heating costs in winter

Another advantage: With an energy absorption of significantly less than 50 per cent, the panes also have a low risk of thermal breakage. For this reason, glazing with sunbelt A51 is significantly more economical. This is because the laminated safety glass can be produced without thermally toughened glass thereby not increasing the risk of thermal breakage.
This also means a lower CO2 footprint compared to toughened facade glass. The Ug value of 1.0 W/(m2K) also ensures that heating costs remain low in winter for extensive glass facades. In this way, glazing with the sunbelt A51 coating makes an active contribution to more sustainability in construction.
"The new coating is to be understood as a sensible further development of our existing product portfolio. However, sunbelt A50 will remain in the range as an alternative," Simon Potts emphasises.
How sunbelt products are versatile
All sunbelt products are available in tape and fixed size quality. If required, the coated glass is toughened. This simplifies the production process considerably, saves time and increases availability. All production steps take place at the arcon site in Feuchtwangen.

This includes the processing of the individual basic glasses into toughened and laminated safety glass, treatment, screen printing, enamelling and coating. This saves long transport routes for the unprocessed parts and allows fast, optimised production and delivery of the finished product within a few days. Combinations with other properties such as sound insulation or an alarm system are also possible without any problems. The sunbelt A51 coating is available to order now.
