Our silica sands—being a high-grade and weather-resistant raw material—also play an important role in the roof sealing segment. It is necessary to use watertight, weather-resistant and fireproof coverings in this segment. Our silica sand has proven itself as a roofing felt coating, in particular for flat roof structures. The use of silica sands for roof sealing has been normal practice for long time, however, roofing felt used to be saturated in hot tar and strewn with sand. The strips of roof felt were then laid in several layers on the flat roof surfaces. This method has been subject to continuous development over the past few decades—from simple roofing felt to elaborate combination systems. In addition, our raw materials—also as a component of glazes for roof tiles—perform an important task in the roof covering segment.
