Project:
The Fact Centre, Liverpool

Installer: Carlton Building Systems Limited
This development
features 2000m2 of zinc cassettes incorporated into the CGL Zinc Rainscreen
System. The panels are 600 x 600mm square and exhibit a superb consistency
of shade which would take many years to achieve through natural weathering.
This 'natural' metal needs no maintenance and will continue to consistently
patinate over the years ( a life span in excess of 60 years will apply)
CGL
Zinc Rainscreen System
GENERAL
DESCRIPTION 
The system comprises preweathered zinc panels which are secret fixed
to the CGL 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 independently tested and are compliant with the 'Standard for Ventilated
Facades' as produced by the Centre for Window and Cladding Technology
at Bath University.
PREWEATHERED
TITANIUM ZINC
Titanium zinc sheeting is a structurally- strong sheeting in 1.5mm thickness.
The material is prepatinated in a factory process and thus gives quality
control over thickness and consistency of finish. 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
Preweathered zinc carries the major benefit of being virtually maintenance-free.
No specific regular washdown procedure is necessary. Any scratching
or abrasions to the surface will "self-heal" by reweathering
over reasonably short periods. Dirt and dust can be removed by washdown
with pure water and a sponge.
WARRANTY
CGL Systems offers warranty over system design and performance for varying
periods dependent on location and material used, covering replacement
of defective product.
