The Caesar porcelain tiles for external use, available in 9, 20 and 30 millimetre thicknesses, represent the ideal outdoor solution, thanks to the surface’s resistance to wear, atmospheric agents and changes in temperature, as well as the fact they are waterproof and frost-resistant. This means that porcelain tiles laid outside are not ravaged by water, do not break and do not crack as a result of changes in temperature. They are also non-slip.
