Technology
THE PATENT
The current patent regards a reinforcement system for
gres slabs, in porcelain or ceramic, marble, travertine or
thin vulcanic stone . For interior and exterior cladidng.
The panel can be divided into three parts:
THE SHEET, with a structural function to resist to push. Sheet are so made:
Internal sheet: wood sheet OKUME reinforced with fiberglass matting (or STAINLESS 5/10)
External sheet: ceramic thin slab reifiorced with fiberglass matting (or stone or glass)
THE GLUING has the important rule to resist to the stress between CORE and sheet mainteinig the panel
compacted.
The Core, the panel’s soul, has got the main function to link the two foils.
It must primarily resist to cutting forces, and partially to flexion. Statically, the core’s paramount function is to
increase the material’s inertia moment, in order to create a distance between the two foils, keeping them in contact
without a relative translation amongst the two. It functions as the soul of an “I” shaped beam, distributing the load
to the two skins, or external foils, as much as the “I” soul distributes it to its wings.
If the core lacks of cutting force resistance, the two foils would work as separate, whilst the core’s high resistance,
along with the adhesives efficacy, allows the two foils to support each other despite of their irregular nature. In this
way, there is a more than proportional increase of the inertia moment among the two foils and therefore the
stiffness of the beam is exponential.
The diagram below wants to give an idea of the tensions’ trend and of the cutting agents in the panel subjected to a
flexional stress for a qualitative evaluation of the Sigma’s trend among the several layers.

FIXING SYSTEM
There are many fixing methods existing nowadays for the invisible hooking system: the ones suggested are the
steel rivets (head + stem) or the positioning of the threaded insert. In both cases, the element that opposes to the
fixing element’s discharge is the stainless sheet steel reinforced with glass fibers, whose mechanical resistance
increases considerably from the structural application to the other layers by means of patented resins.
PULL-OUT VALUES FROM INTERNAL LABORATORY REASEARCH:
Extraction of a steel rivet, nail diameter 4.88mm, Head 9 mm: kgf 80.
Extraction of a steel structural rivet, nail diameter 4.88mm, Head 9mm: kgf 150
•FISSAGGIO DEL PANNELLO ALLA SOTTOSTRUTTURA
FIXING POSITIONING
As shown in the diagrams below, there is a crown around the head of the rivet or the threaded insert, within
which the deformation of the sheet steel takes place and consequently the discharge of the rivet from the panel.
Around it, it would be appropriate to track another security zone. The minimum distance from one fixing point to
the other (if linked to different hooks), or from the rivet and the edge is represented by the safety round crown.

SPECIAL PRODUCTIONS | ARCHITECTURAL ELEMENTS COVERING
The Gammastone AIR panel, thanks to its dimensions e its
possibility to be cut in sub-multiples according to the
planning requirements, allows the realization of covers for
architectural elements that are structural but unsightly,
conferring it a monolithic aspect that matches the rest of
the façade.

FURTHER EXTERIOR APPLICATIONS | SUN LOUVRES
Their main function is to contrast solar radiation within a
building carrying out, therefore, a crucial energetic role,
and also to nullify the luminous dazzle of the internal
environments, increasing thence their comfort.

Q&A
Here is a list of hypothetical questions and its brief but concise answers, exploiting the
certification achieved at the Istituto Giordano.
.
PHISICAL AND MECHANICAL PROPERTIES OF THE PANEL
Q: What is the panel’s behavior when undergoing loading management?
A: Thanks to its stratigraphy, the composite Gammastone AIR Panel confers to materials
generally weak such as Gres and natural stones a high degree of tenacity (resistance to
static loads) and a high resilience (resistance to impulsive or sudden loads).
Q: Could the panel defoil or the layers unstick?
A: The sticking of the layers the compose the Gammastone AIR panel is a structural one, and it is achieved by
means of special bi-component resins disposed in an uniform way all over the surface of the panel, without
discontinuity points not even along the depths.
Q: What is the warranty on the Gammastone product?
A: 25 years warranty insurance on damage caused by an improper manufacture of the panel, along with a 25
warranty on the inalterability of the colour of the ceramics, except for the finishing that contain iron in the
pigment.
Q: Which pull-out values do the rivets or the threaded inserts achieve in the sheet steel?
A: According to the used device, the pull-out values go from 120 to 180 kgf. To these absolute values it is of
paramount attention to apply the safety coefficient based on the ruling legislations.
Q: Can I pierce or drill the panel while building?
A: Of course you can. The Gammastone AIR panel can be worked on in a very simple way. With standard diamondcut utensils.
APPLICATION ON VENTILATED FACADES
Q: What depression load can the panel bear if installed in a ventilated façade system
similar to the one you’ve proposed?
A: Since we are talking about a system, i.e. numerous components assembled with one
another (clamping, alloy pillars and currents, hook, and then panel) it all depends on how
these are shaped and interconnected. For example, a Gammastone AIR panel resisted to
a depression load of over 450 KG.
Q: Which tangle do you suggest to use for the sub-structure of the ventilated façade
rather than the other types of façade?
A: It depends on the use of the façade and the loads it is subject to. But generally
speaking, the mechanical performances of the Gamamstone AIR panel you can save up to
10-15% of the sub-structure.
Q: What are the advantages/savings for putting up a Gammastone AIR panel on a facade?
A: The Gammastone AIR panel allows a higher manufacturing productivity thank to its big
dimensions, with the consequent optimization of the installation and setup. Furthermore,
its light-weight avoids using heavy machinery which are usually used for natural stones.
Opposite to the composite alloy panels, there is no need for a team to be employed in
the transformation of the flat layers, leading to the need to less work hours.
Q: Execution speed: how many square meters can a construction site team build in a
day?
A: On the average, it is possible to count up to 15% less compared to a ceramic facade,
with the productivity estimated to be of 1.2 hours per square meter. You can save up to
25% compared to natural stone façades thanks to its light-weight and simplicity in
operating the sheets.
Q: How long is the durability in time of the Gammastone AIR panel?
A: Ageing simulations have been tested in a laboratory, giving us outstanding results in
terms of stability and durability.
Q: Which alterations can the panel suffer if installed in particularly aggressive weather
conditions, such as a seascape?
A: None. As confirmed by the tests in the laboratory based on the corrosion of saline
mist.
Q: What is the Gammastone AIR’s reaction to fire? Is it considered as a combustible
product, or could it even spark the fire? Does it release toxic gas or harmful leaking?
A: Absolutely not! The product is altogether classified as Class 1, that is to say that it’s
impossible for it to combust or leak. Its combustion releases breathable fumes and not
toxic. It does not spark fires since it does not spark flames. And once you distance the
panel from the heat source, it will arrest its combustion autonomously.
PS: In special applications, where the edge of panel is protected from fire (example:
frame applications), the Gammastone AIR panel supplies the flame only with its two main
sides, i.e. the natural stone/Gres and the sheet steel, that are incombustible by nature.
Q: Could the panel suffer damage due to galvanic corrosion in points of contact with the
alloy sub-structure?
A: Since the Gammastone AIR panel is made of INOX Steel, a more noble material than
alloy, it could actually lead to a minimal corrosion, but not on the panel. Our experience
highlights that the this corrosion is mainly superficial and it doesn’t alter the mechanical
properties of the materials.
Nonetheless, we leave certain evaluations of electronic dividers or safety devices to the
single project.
Q: What is the panel’s behavior in the face of temperature leaps in an exterior
environment?
A: Tests based on freeze and unfreeze cycles have been done, that confirmed the
inalterability of the panel when facing temperature leaps.
Q: Could the edge of the panel absorb water? Could it suffer damage if exposed to
freezing weather?
A: Absolutely none. The Gammastone AIR panel absorbs water in a very minimal way, less
that 1% and it doesn’t suffer any damage due to freezing since it has been declared nonfreezable.
