Microventilated facade

GammaStone AIR, that proved to be the most effective composite panel in the international market, suits perfectly for microventilated facades.
The microventilated façade is an external cladding system that creates a thin air gap (open on the top and on the bottom) between the external face of the perimetric wall of the building and the external environment.
This air gap creates a “chimney effect” that allows the ascending movement of the air that avoid condensation and dissipates the water vapor coming from the inside of the building.
microventilated cladding system suits peculiarly to old building renovations and in the projects with severe spatial constrains.
All the external material solutions within GammaStone AIR range fits to the realization of the microventilated facades.
GammaStone AIR is an unmatched cladding material, it proved to be the most effective in complying with microventilated facades in the international market.
This innovative paneling system for ventilated façades was developed in collaboration with the largest and most reliable companies in the sector.
Together with our partners we reached top results referring to insulation, protection from weather events and from external noises.
The GammaStone AIR panels allow easy installation, versatility in architectural design, original stylistic solutions with a wide choice of large-sized marble, granite and porcelain slabs.
GammaStone AIR microventilated facades are structurally reliable. Our panels undergo strict tests against wind, compression, hurricanes, etc.
They are installed on a metal hanging structure fixed to the wall of the building with layers of insulation and protection materials are assembled within.
External panels give protection and isolation to the façade by creating an air gap between external environment and the perimetric wall of the building.

Further details
Even with little space available, the system allows to realize an opaque wall of the maximum thickness of 40-60 mm made of dry installing panels. The system is made up by mechanical suspensions and aluminum fasteners; those are separated from the rear wall (on which may be a heat-insulating panel) by an air gap. This gap is thin but enough to stop the physical continuity between the outer lining and the perimetric infill.
The metal substructure is made up of only horizontal rails, fixed directly to the wall behind with metric thread with the classic bayonet system anchored by rivet on the back of the panel.
The micro-chamber of ventilation however has to be dimensioned referring to of the thermofluidodynamic calculations of the facade.
