Tiles are therefore building materials that
add the finishing touches and must serve two purposes:
- A design function
- A technical function as a building
material that is able to withstand, without cracking or deteriorating,
the various types of stress to which it is subjected by its environment.
Hence the general criteria that must
be considered when choosing tiles:
- The design criterion depends on taste
and the pleasure given by the different decorative arrangements.
- The technical criterion based on knowledge
of the materials and their physical properties and their suitability
for the environment in which they will be used.
