|Podstawowe dane techniczne:
Concrete roof tiles are a construction material belonging to a broad group of roof tiles. They can have various shapes and colours. They compete with ceramic tiles on the market. Many people say that they look great on roofs and are fitting for elegant houses.
Concrete roof tiles have been produced on the industrial scale since 1844 and, from that moment on, have been a cheaper non-flammable roofing alternative for ceramic roof tiles. The originator of the production of this type of roof tiles was a German man Adolf Kroher, but they gained extraordinary popularity during the period of the industrial revolution in the 19th-century England. That was the country where the first industrialised technologies of production processes were developed. In Germany, concrete roof tiles have been the most popular roofing material to this day.
Concrete roof tiles are manufactured using a special fast-setting cement, sand, water, and dye.
The cement used in this production is different than the others in that it sets very quickly. The production of concrete roof tiles uses a relatively small amount of energy: 12 kWh/m2 of coverage. Such a small demand for energy results from the lack of the need for firing of refractory shapes or for the energy-consuming drying of the product. The later production stage consists in coating the concrete roof tiles twice with acrylic paint, which improves its appearance and texture. Its durability is relatively high, since some manufacturers give as many as 30 years of guarantee for their products.
