External porphyry stone cladding from Trentino

Porphyry: an ideal material for coatings

Porphyry is a particular type of volcanic rock belonging to the "Atesina Porphyry Platform", an enormous complex of volcanic rocks that extends into the Trentino-Alto Adige region. These rocks, extremely varied and differentiated, both as a chemical composition and as a form of formation, are the result of an intense volcanic activity started 260 million years ago in the Permian period, and continued for several million years with a continuous repetition of eruptive phases and stasis phases. Among the various methods of deposition of these rocks, the so-called ignimbrites take on particular importance, as these are the ones that gave rise to the "porphyry". These are flows of liquid-gaseous mixtures with thicknesses generally ranging from 5 to 20 meters and with a fairly constant chemism, up to the so-called ignimbritic unit, which reaches hundreds of meters thick.

External porphyry stone cladding from Trentino

The external cladding stone are always the optimal solution that combines great durability and aesthetic effect of merit. Natural stone is increasingly used for indoor and outdoor flooring, stair walls and wall inserts: the materiality of the stone conveys that feeling of psycho-physical well-being appreciated by all designers.
Porphyry is an effusive volcanic rock, composed of a bottom of vitreous paste in which small quartz crystals of feldspar and micas are immersed, so as to give the stone a color that varies from light gray to medium brown. Thanks to this particular composition, porphyry is the optimal solution for external stone claddings because it is one of the most resistant materials to wear and moisture, able to react to the attack of chemical and atmospheric agents.
The porphyry, since its extraction, is characterized by a regular morphology that makes it versatile for any type of use: in fact, it is suitable for :

• external or internal coatings
• urban and private decorations
• driveways
• pool edges
• coating of walls
• gardens coverings
