Modern glass facades are an expression of contemporary architecture. Glass ensures plenty of natural daylight, which has a direct positive influence on well-being and quality of life. However, large areas of glass may also give rise to undesirable heat build-up in summer. solar control insulating glasses permit optimum use of the natural light source and can also prevent solar energy causing excessive increases in room temperatures. With solar control glasses, the indoor climate remains pleasant and comfortable even in summer while energy costs for air-conditioning are also reduced. These interrelated functions optimise the overall energy management of buildings in a cost-effective way.
