Leader in roofing Right from the beginning Alubel's purpose was to specialize in metal roofing and boasts a leading position in the national market with its flagship product – the “Alubel 28 System� priding itself on the great number of imitations

Fifty years later, from the first pioneer years and now counting on a great number of employees that know how to work coherently with its history and with renewed enthusiasm capable of brilliantly addressing issues and finding the best solutions:

the issues are our challenges and these challenges are what have kept us focussed on bettering ourselves over the years.


Alufon produces a wide range of systems for sound absorbing barriers in category A4 and sound insulating barriers in category B3, designed to achieve the highest possible results in reducing noise and in line with national and EC standards. The Alufon anti-noise barriers can be used anywhere, both for civil and industrial applications, along roads or railways or even installed as a shield facing a disco or a building with a noisy production business. They are also used as anti-noise coverings for industrial machinery.

STRONG POINTS Besides an adequate level of acoustic absorption and insulation, the Alufon anti-noise barriers also guarantee: • flame retardancy, resistance to the elements and wind; • lightness and ease of assembly; • construction simplicity, appearance that remains intact, blending in with the environment; • use of materials that are able to transform some of the sound energy into heat and to dampen vibrations; • possibility of integrating other types of panel, using translucent, wood or even concrete ones; • a choice of different colours for the external finish as per the RAL Sikkens catalogue;

Alufon aluminium panel, 1.2 mm polyester with sheath DESCRIPTION

Sound absorbing panel consisting of two cold formed 1.2 mm aluminium alloy sheets assembled with a bayonet coupling so that no screws are needed. The standard measurements of the box-type structure, with a bearing and sound absorbing function, are 2960 x 500 x 105 mm; it is first pretreated with a dip cycle and then finished with a polyester powder paint polymerised in the oven at 200°C to guarantee resistance against the elements. The sound abatement function - to ensure the very best sound absorption properties near the most polluting sound sources is guaranteed by a polyester fibre panel -70 mm thick with a density of 40 kg/m3 - mounted centrally in relation to the box element, and thanks to a 4-5 kg/m2 thickening sheath. The front protective aluminium element is drilled with an empty-to-solid ratio of about 37% of the surface with 10 mm and 5 mm diameter holes with a 13 mm pitch and alternating at 60° to enhance the sound absorption properties while the rear element is a solid aluminium wall acting as a sound barrier. The sides of the panels are closed with talc-filled polypropylene heads that ensure their durability, resistance to temperatures, resistance to the elements and a perfect seal between the panel and the barrier’s bearing structure. These panels are assembled one on the other with a tongue and groove fitting along their whole length. Acoustic certifications in category A4-B3. Sound absorption coefficient (αs)

The standard measurements of the box-type structure, with a bearing and sound absorbing function, are 2960 x 500 x 105 mm; it is first pretreated with a dip cycle and then finished with a polyester powder paint polymerised in the oven at 200°C to guarantee resistance against the elements. The sound abatement function - to ensure the very best sound absorption properties near the most polluting sound sources is guaranteed by a mineral fibre panel mounted centrally in relation to the box element. It is 60 mm thick with a density of 90 kg/m3. The part of the panel exposed to drilling is backed by resined, water repellent, siliconed glass fibre to ensure resistance and duration against the elements and ultraviolet rays. The front aluminium element is drilled with an empty-to-solid ratio of about 33% of the surface with 10 mm diameter holes and a 14 mm pitch to enhance the sound absorption properties while the rear element is a solid aluminium wall acting as a sound barrier. The sides of the panels are closed with talc-filled polypropylene heads that ensure their durability, resistance to temperatures, resistance to the elements and a perfect seal between the panel and the barrier’s bearing structure.
