Concrete tiles can be bricks and roof tiles

Under the name Concrete Tiles three concrete products are summarized. Roof tiles made of concrete, hollow blocks for masonry and the similar formwork blocks for the subsequent pouring are subsumed under this term. The roof tiles, such as the popular Frankfurter pan, are usually used in earthy colors and are reminiscent of clay tiles.

Hollow block, formwork and roof

While only the functionality as a choice criterion plays a role in hollow block and formwork blocks, the choice between clay roof tiles or concrete roof tiles is often due more to the personal taste than the material. Where thirty years ago, there were still significant differences, only marginal differences can be seen now.

As a property that was often the decisive factor in earlier times, the vegetation of the roof covering was covered with moss and algae. Due to their porosity, earlier concrete products were much more susceptible to "greening" than clay roof tiles. The manufacturers of concrete roof tiles have further developed the production processes and modern roof tiles are no longer inferior to the clay.

Another argument for answering the question of whether concrete or clay tiles should be chosen was price for many years. The clay tiles were for a long time much more expensive than those made of concrete. With the advancement of technology and the new manufacturing processes, the prices of concrete bricks have approached the products of clay. Top concrete products with special sealing and finishing properties sometimes cost more than clay tiles.

Classic tile shapes

Concrete tiles for the roof are available in several classic pan shapes, often bearing names with regional references. The classics are:

  • Frankfurt pan
  • Harzer pan
  • Taunus pan
  • Finkenberger pan
  • S Stone
  • crown pan
  • Sigma-pan
  • Mecklenburg pan

For all concrete roof tiles, extensive accessories are manufactured as part of roof systems. Snow guards and kickers are just as much a part of this as pigeon guards, trap stones, ridge and ridge elements and roof passages.

Hardening and silting

Modern concrete roof tiles are increasingly no longer distinguishable from clay roof tiles. Diverse surface finishes create very similar to the sound optics. The typical colorations arise in most cases by iron oxides mixed into the concrete. These can be released from the concrete bricks after a long time if weathering causes a slight sanding of the concrete.

The small amounts of rinsed sand carry the coloring pigments out of the concrete bricks. This process has no effect on the static stability of the roofing, but does affect the "color fastness" of the roof. This process normally starts after a lifetime of around twenty years and can be extended by several years with a seal from the manufacturer.

A specific property of concrete bricks is the increasing resistance to weathering with increasing age. The concrete hardens for several years and becomes harder and more stable and reaches its maximum durability after five to ten years.

In addition to the two largest concrete tile manufacturers in Germany, you will also find many regional medium-sized companies with nationwide delivery.
