CS - Coelho da Silva produces flat, Portuguese and Marseille clay roof tiles using state-of-the-art technology such as plaster moulds, hydrocasing firing and H-shaped, flat and individual refractory supports. The company is a certified ISO 9001:2000 manufacturer and all of its products are certified by European standards.

CS - Coelho da Silva's roof tiles and fittings are mainly characterised by the use of plaster matrices, which allow for an unequalled surface finish and the incorporation of lips for an unrivalled watertight seal - and the hydrocaslng firing system with individual supports. This allows firing to take place at higher temperatures without deformation or warping.
