The problem of building contamination is the underlying cause of the so-called “sick building syndrome” and of a number of illnesses and allergies. Toxic or harmful substances (dust, pollen, spores, bacteria) can be released into the interior of buildings by the materials used in the construction industry or for furnishings, or may come from the environment outside.
A number of EPA studies into human exposure to polluted air estimate that the level of contaminants indoors is between 2 and 5 times higher – with peaks that are much higher still – indoors than outdoors. This is a particularly serious problem if we consider that most people spend about 90% of their time indoors.
Among the materials available to design engineers, it is clear that it is preferable to choose those commonly known as “low-emission” materials. Porcelain stoneware – because it is chemically and physically inert as a result of the high-temperature heat treatment that concludes the manufacturing cycle – guarantees excellent performance from this point of view, avoiding the release of any type of contaminating substances (Lead, Cadmium, etc…).
