Case Study

Project: Residential Development, Western Harbour, Edinburgh
Architect: Cooper Cromar, Edinburgh
Installer: Taylor Woodrow Construction Ltd

This housing development features 16,000m2 of FF2 PVdF coil coated aluminium incorporated into the CGL Aluminium Rainscreen System. The panels were supplied in 4 colours and the system was designed by CGL to accommodate the exceptionally high wind loads caused by the exposed site position directly onto the Leith seafront.

CGL Aluminium Rainscreen System

GENERAL DESCRIPTION
The system comprises FF2 aluminium cassette panels which are secret fixed to the CS3 extruded aluminium hanging system. Being a rainscreen system, this facade is ventilated and requires to be hung from a structural internal wall which is air-impermeable, insulated, and acoustically satisfactory. The cavity between the backing wall and rainscreen is pressure equalised and thus inhibits the ingress of driven rain and also allows any penetrating moisture to dry out naturally. All CGL systems are independantly tested and are also compliant with the 'Standard for Ventilated Facades' as produced by the Centre for Window and Cladding Technology at Bath University

FF2 PVdF COIL-COATED ALUMINIUM
Manufactured by Novelis, FF2 sheeting is a structurally- strong 5754H42 aluminium alloy in 2mm thickness which has equivalent performance to the traditionally-used 3mm 3000 series alloys, which are typically post-coated. FF2 is coil-coated and thus gives factory control over quality, thickness, and consistency of colour of the PVdF finish, together with excellent colour fastness, longevity, and warranties as to performance. CGL has developed extensive expertise in fabricating cassettes , cappings, curved details, and louvres from this material and takes full responsibility for designing the structural attachment and stiffening of the panels.

CGL CS3 SUPPORT SYSTEM
Rainscreen support system technology under the CGL brand gives the installer total flexibility to produce a flat, modular facade to exceptional tolerances. Essentially a vertical rail system with wall brackets, the design detail built into the extrusions and tension cam connectors is unequalled in this market. All materials are aluminium, stainless steel, and neoprene compression gaskets.

MAINTENANCE
Generally, painted aluminium facades should be washed down annually with clean water, a neutral cleaning agent, and a soft applicator. This regime will assist in achieving the expected longevity in excess of 30 years.

WARRANTY
CGL Systems offers warranty over system design and performance for varying periods dependent on location and material used, covering replacement of defective product.
