Ventilated walls

We have been specializing in the design, production and installation of ventilated walls since the 80s.
We work on a world-wide scale using the most advanced technologies and are able to create the most complex and original designs.

A ventilated facade is a protective or decorative surface applied as an external layer to the vertical perimeter walls of buildings.

The ventilated facade is anchored to the walls of the building with metal structures and supports made from aluminium/ galvanised steel and stainless steel.

A space must be left between the ventilated facade and the wall of the building to allow external insulation of variable thickness to be inserted. An "air curtain" of between 2 and 20 cm must therefore be left.

The ventilated facade is often used to mask the less aesthetic elements of various systems on the outside of the building and, if stone is used, does not require constant maintenance.


Metal structures suitable for the installation of a ventilated marble facade can be split into two main types:
  • precision system
  • system with substructure
Within the scope of these two main systems for ventilated facades there is a large variety of solutions on the market. These solutions must be assessed in terms of the walls of the building, the shape and weight of the marble slabs forming the ventilated facade, wind pressure, the height of the building and the complexity of the cladding pattern. We are confident that the ventilated facade will be a constant element in buildings of the future and marble, stone or granite ventilated facades will undoubtedly play a leading role in the appeal and originality that only natural materials can convey and retain over time, regardless of changing fashions and architectural styles.


With more than thirty years of experience in ventilated facade/walls sector, Zanet is able to provide:
  • technical advice for designers about installation systems and the types of stone suitable for ventilated facades;
  • sizing of substructures and buttresses;
  • checking of slab sizes according to the stone material selected;
  • suitability testing of the walls of buildings with appropriate jerk tests;
  • executive cladding pattern design;
  • supply of marble, stone and granite slabs complete with Kerf and the FZP holes required for installation;
  • coordination and assistance for specialist installers for fitting ventilated facades;
  • certification of materials according to standards in force.


The costs of a marble ventilated facade can be competitive even compared with a ceramic facade but, of course, with a very different result in terms of aesthetics and substance.

With careful design, the costs of ventilated facades can largely be absorbed by the saving achieved through the modifications that this type of cladding allows. In fact, wall insulation can be simplified with a simple outer cladding that does not require particular trimming or painting.

The cost of obligatory external system structures can be kept low as they are not visible, given the masking of this cladding. Above all, however, the ventilated facade allows air to flow naturally (via a stack effect) between the outer "skin" and the wall of the building. This allows improved overall thermo-energetic performance.
