Clay roof tiles are high performance materials which meet stringent quality and design requirements for quality construction and renovation work. They are industrially manufactured by pressing pre-formed clots or cakes of terracotta clay between two plaster moulds, which represent the negative of the required shape. In order to obtain optimal precision, quality of detail and dimensional accuracy, high performance moulding plasters are required. Through years of process and bespoke product development expertise, Saint-Gobain Formula, has developed a comprehensive range of high performance roof tile plasters under the Teha™ brand:
- High strength to withstand the high pressure exerted during mould pressing.
- Resistance to abrasion, which results in longer mould life,
- Adequate porosity to absorb the quantity of water extracted from the clay compound during pressing
