As for the materials to be used to create the real external diaphragm of the ventilated facade, let’s look at the main materials for this type of use.
Aluminium is the contemporary material that is most suitable for outdoor positioning. It is, as mentioned above, light and performing from a technological and structural point of view. Being the son of modern industrial production, It is characterised by a very high flexibility in production and use. We can find it in multiple formats. It is mainly applied on facade cladding systems, such as:
Furthermore, it can be applied, in the form of a expanded metal panel, on systems such as Tetris Mesh, or on systems with trapezoidal sheet panels, or even on a corrugated sheet panel.
The great versatility that characterises it makes it an attractive material especially for the designer. In fact, depending on the specific product chosen, its formats and the imprinted colours, aluminium can lend itself to more conservative or more innovative external solutions.
Able to marry existing and historicised contexts with a function of accompaniment and service, but also to take on the role of protagonist for avant-garde and markedly contemporary designs.
HPL panels, are high-pressure laminates, classified EDF in the EN 438-6 standard, are made with special presses through the combined action of heat and high pressure. The use of double-hardening polyurethane acrylic resins guarantees effective protection from atmospheric agents, making them particularly suitable for durable covering of balconies and facades.
This material is scratch, solvent, hail and impact resistant in accordance with EN ISO 178. Easily cleanable, it is suitable for all outdoor uses, giving the facade a perfect characterizing connotation thanks to the infinite variety of finishes.
Wood is an ancient material of great visual and scenic impact. The beauty of its essences is beyond question. It is still used as a cladding for external facades, even ventilated.
It goes without saying that the arguments cited above ring a bell as regards the durability of the material, its maintenance and the costs associated with it. Among the pros that should be mentioned, wood is thermally insulating.
Stone is an integral part of our architectural heritage and is outlined as a material of great presence and elegance. There are multiple types of stone but, sometimes, those that most fall into our imagination, since widely used since the past, are not very suitable for outdoor use.
An example is sandstone. However, these themes need a specific focus since there are many stones of considerable durability and, even among sandstones, there are certain products that perform better than others. A 3 cm thick stone slab shields well from solar radiation, but pay attention to the weight!
Brick, or baked clay, is an excellent solution to use. Even in many contemporary architectures it plays a lead role. Also because, thanks to today’s production technologies, the formats are among the most disparate: quadrilateral elements with right angles, quadrilateral elements with non-right angles, smooth elements, elements with superficial processing, oblong-shaped elements list type and similar.
Porcelain stoneware belongs to the family of ceramic materials mentioned above and nevertheless reports some improvements in terms of resistance to mechanical actions, abrasion, rubbing and impact. It is highly waterproof and can also be subjected to numerous processes and aesthetic effects. The stoneware is able to resemble the effect of wood or that of marble in a remarkably realistic way. In addition, the colours, the material effects and the formats that can be obtained leave us spoiled for choice.
Polycarbonate is often used in contemporary architecture due to its elegantly minimalistic nature, typical of a strong design will. The most relevant positive aspects are the great flexibility in formats, colours and in the effects of transparency and opacity. It has remarkable resistance to water.
