raw materials that are widely present in the earth’s crust and do not yet run the risk of depletion, derived from the decomposition of rocks – such as quartz porphyry, granite, syenite, gneiss- rich in minerals that build clay. These materials determinate the vitreous process that ensures the compactness of ceramic products.

the footing, also known as concrete slab, is a building element of variable thickness from 4 to 8cm, created using cement mortars. It can be installed onto a load-bearing support (i.e. floor), onto a separating support (i.e. vapour barrier) or onto a thermal and/or acoustic insulation layer and depending on the aforementioned installations, the footing can be defined as “adherent”, “separating” or “floating” footing, the latter, if incorporated into heating coils is called “heating” footing.

it depends on the porosity or water absorption of the material: the lower the water absorption is, the lower the damage due to frost.

typical features of low porosity materials, resistant to frost and suitable for outdoor use.
