Perforated cladding sheet metal provides a remarkable finish when used as facade cladding or secondary cladding. For facade contractors and metalworkers, standard round perforations combine several functions: cladding, protecting, and ventilating the building envelope.

Perforated cladding is often used as a second skin: it hides imperfections in the building structure, embellishes a bare concrete facade, and provides sun protection or a sunshade effect. Thanks to the round perforations in the metal mesh, the cladding allows air and light to circulate, creating a visual effect that changes depending on the position of the sun.

We deliver perforated sheet metal to metalworkers, cut to size according to the building's specifications to facilitate installation: cassettes cut to size according to the facade's design, panels folded according to the layout. Rectangular perforation patterns can be aligned with the building's grid to give a vertical impression or offer a deliberate graphic contrast by combining round holes. On the underside of apartment building balconies, standard round perforated sheet metal also prevents black streaks visible from the street, while ensuring a uniform façade.

In metal cladding, standard perforated sheet metal with round holes and patterns such as R20T25 Jocapel, C20U32 Tirol R6M12 Millet offers a multitude of advantages for facade cladding in a variety of contexts, such as urban buildings.

The classic perforated sheet metal catalog is extensive enough to offer effective customization of facades thanks to an infinite variety of patterns, such as the standard R20T25 round and C20U32 square perforated sheets. This diversity gives architects and designers creative freedom to design unique building envelopes that blend in with their urban environment or reflect a brand's visual identity. By playing with the size, shape, and arrangement of the perforations, it is possible to create dynamic visual effects and plays of light and shadow, adding an artistic dimension to facades. In addition, the ability to choose from a wide range of finishes and RAL colors allows perforated sheet metal to be integrated into various architectural styles, whether modern or traditional.

The round perforations in the sheet metal promote natural ventilation in buildings, which is essential for maintaining optimal comfort, particularly in technical rooms or parking garages in cinemas and shopping centers. This natural air circulation reduces heat build-up and removes humidity, thereby helping to reduce air conditioning requirements. Energy and maintenance costs are reduced by the evacuation of hot air and the entry of fresh air. Perforated sheet metal actively contributes to the thermal regulation of buildings, improving the well-being of occupants. In technical areas and underground parking lots.

Forced ventilation is required to achieve the correct airflow rate for air exchange between the interior and exterior. The Hexagonal Xari Liboma models Liboma honeycomb perforated sheet metal are the most effective for achieving a transparency rate of between 50% and 60% of the void.

Depending on the density of solid areas and the layout of the perforations, perforated sheet metal can act as an effective sunshade, filtering natural light and reducing glare inside buildings. This passive sun protection helps maintain comfortable indoor temperatures, limiting the need for air conditioning and thus achieving significant energy savings. In structures such as hotels, office buildings, or public spaces, where occupant comfort is paramount, the use of perforated sheet metal to control solar gain is particularly advantageous.

Compared to other cladding materials, perforated sheet metal is relatively lightweight, making it easy to handle and install on facades, whether in new construction or renovation projects. 2 mm aluminum perforated sheet metal with 30% open area weighs just 3.9 kg/m², making it particularly easy to carry on scaffolding. This lightness reduces the load on the building's supporting structure and can simplify the installation process, resulting in lower labor costs and shorter construction times.
The perforated sheet metal panels are prefabricated to measure using the configurator, adapting perfectly to the specific dimensions and shapes of the facades to be clad. The numbering of the parts according to the facade plan saves time during installation.

Made from materials such as aluminum or galvanized steel, perforated sheet metal offers excellent resistance to varied weather conditions, corrosion, and vandalism. The mechanical strength of the metal ensures increased longevity for facades, reducing maintenance and repair needs. In urban environments subject to pollution or in coastal areas exposed to salty air, perforated sheet metal is a wise choice for preserving the aesthetic and functional integrity of buildings. Surface treatments are then adapted to the exposure of the sheets.
