Stefani’s terracotta tiles and bricks have been analyzed by the members of the European Network of National Ceramic laboratories, that certified the perfect resistance to the frost and the temperature difference, the mechanical resistance and the water absorption capacity.
Also, according to other tests, in our clay “there is no radioactivity and Radon problem” and that “the values are the same of the most common clays at lower natural radioactivity level”.
All this shows once more the unconditional quality of our raw materials and working process, that make our product the most suitable for Green building.
