Matiria is a new project that joins together the natural properties of the clay with the innovative technology of the carbon fiber. The natural characteristics of the clay, such as: low thermal conductivity and good mass, high accumulation of heat with slow and gradual release in the ambient and micro porosity that reduces and dispels excess humidity, harmoniously blend with the high-tech characteristics of the carbon fiber: no polluting emissions, no magnetic fields, reduction of installation and energy consumption costs, and no periodical maintenance requirements.
