BB-CH

BB-CH is a kit system based on hung cassettes made of Buildbond® aluminium composite panel, designed for the installation of ventilated façades. It is a concealed-fixing system, versatile and quick to assemble, conceived primarily for vertical modulation. The structural lightness of the assembly and the optimised load transfer make project execution more efficient, while the omega rails of the substructure allow the panels to be adapted and curved, meeting the most demanding architectural cladding requirements.

The substructure consists of omega rails and spacers, available in various lengths to accommodate the desired thermal insulation thickness and to compensate for irregularities in the wall. Thermal breaking is ensured by insulating shims placed between the spacers and the vertical wall. The spacers are anchored to the wall with mechanical fixings suited to each type of substrate and receive the omega rails as vertical members.

The suspension brackets are placed on the vertical members, with a dedicated EPDM part in the support area to prevent vibration. The Buildbond® cassettes rest on these brackets through slots machined in the vertical returns and in the concealed stiffeners on the inner face, and are then screwed or riveted through the upper returns to the vertical members, with no visible fixing on the façade plane. As it shares the omega-rail substructure, BB-CH can be combined within the same project with other Alubuild systems of the same group.

For each project, Alubuild’s technical department carries out the specific calculation of the substructure, defining the maximum spacing between rails and the number of fixings required.
