Your ALUMINUM Wall Cladding System Experts
There is one thing we can all agree on within the construction industry, and it is that the popularity of aluminum composite panel has not stopped growing over the past few years. Its use has been expanding under the cover of energy efficiency, low price and construction possibilities.
In this article you will know everything you need to know about the aluminium composite panel, how it is produced, its main characteristics, finishes, transformations and its most popular uses.
How aluminium is obtained
Aluminum is the third most common element found in the earth's crust. In its natural state it is found in many silicates, and is extracted from the mineral known as bauxite, a sedentary rock with a high aluminium content.
As a metal, its low density and resistance to corrosion, in addition to being a good conductor, make it an extremely useful element for many industrial processes.
Currently, with China leading the way as a producer, it is estimated that around 60,000 metric tons are produced annually, 20% of which are recycled.
Main characteristics of aluminium
Among its usual uses, and it could looks incredible, is the manufacture of mirrors (thanks to its optical properties), containers and cans or, of course, as aluminum foil for domestic use. It has multiple standards of alloys that fit to sectors as diverse as the automotive industry, telephony or construction.
Aluminium can be easily combined with other materials to produce new materials such as those used in briks or in the composite panel.
Composition and elaboration of the aluminium composite panel
The aluminium composite panel is divided into three groups depending on the mineral load of its core (from 0% to more than 90%), and can be incombustible or fireproof and, in some cases (according to UNE 13501-1:2007), classified as A2-s1, d0 and B-s1, d0.
The composite panel is produced by a continuous lamination process, in which a sheet of the material that will make up the core is extruded and compacted between two aluminium sheets that are unwound at the same time. Finally, the flatness of the material is compacted and perfected and a protective film is applied.
Uses of the aluminium composite panel
As I told you before, its most common use is in ventilated facades, a type of coating system in several layers that stands out for its effectiveness in solving the buildings insulation, thanks to the thermal behavior that the facade achieves.
The most curious thing about the ventilated facade is that it allows the creation of a chimney effect between its layers. This chimney generates a continuous ventilation in the chamber, maintaining a stable temperature that results in greater energy efficiency compared to more conventional systems. Thus, during the summer, the heat is evacuated and the circulating air is renewed. In winter, air circulation is slowed down, preserving the heat.
Composite panel type we have
In the case of the A2 panel, this is a non-combustible panel composed of a mineral core developed to meet the highest regulatory requirements of fire classification.
Its reaction to fire classification A2-s1, d0 (according to UNE EN 13501-1:2007), makes it the ideal cladding solution for high-rise buildings and high occupancy.
