Suitable for use on a building envelopes exterior facade in high-rise, hospitals, student accommodation and hotel applications.

CGL is a rainscreen cladding system with horizontal or vertical Traypanel cassette type panels discreetly fixed into an extruded aluminium support structure, supported by helping hand brackets attached back to the primary structure. The rainscreen wall design shall include all components such as membranes and insulation that together will ensure compliance with current building regulations.

The system is a drained rear-ventilated rainscreen façade. Air pressure in the cavity behind the panels generally equalises with pressure outside to prevent wind-driven rain from entering the cavity. Any moisture which does enter the cavity, drains down the back of the panels and exits in a controlled fashion at horizontal or vertical joints and the base of the facade.

In order for the rainscreen principle to function, the backing wall from which it is supported must achieve certain standards of air permeability, stipulated in The Building Regulations, and be capable of accommodating transmitted live and dead loads. The backing wall must also achieve specified performance requirements for fire, acoustics, and condensation risk.

The system have been formally tested with certification from a UKAS accredited testing facility, which complies with testing requirements laid out in the CWCT publication, 'Standard for systemised building envelopes - 2005'.

Features and benefits:

• Precision made with maximum 30 mm joints in both directions. Suitable for large and bespoke sizes. Can also be supplied perforated, if required.
• All season installation.
• Easy maintenance.
• Mechanical fixing methods with no use of flammable adhesives.
• Stiffeners/ carriers, if required are stud welded to rear of panel (subject to product design review).
• Ventilated system.
• Designed and tested using fully adjustable Hilti MFT-MFI brackets in conjunction with either vertical or horizontal support rails.
• Fire tested to BS EN 13501-1 certification.
• Centre For Window & Cladding Technology Sequence B Dynamic Tested in accordance with NHBC testing requirements.

With the exception of Cor-Ten Steel, a removable protective film is supplied on all panels and remains in place through the installation processes to inhibit damage. CGL recommend the film be removed on the day of panel installation otherwise there is the risk that adhesive residue/staining will remain on the panels after later removal.
