Case
Study
Project:
Ramada Encore Hotel, London
Architect:
Hamilton Associates
Installer: Parry Bowen Limited
This new
hotel development was designed by Hamilton Associates who wished to
create a landmark project by the use of a stunning red polyester paint
finish to the 3mm thick cassette panels supplied as the external element
of the CGL Aluminium Rainscreen System. In addition, the colour was
applied to a 70% gloss factor and to extremely tight thickness parameters,
as variable coating thicknesses show up as different colour opacities.
The project was successfully completed in April 2004 and has met the
client's aspirations.
CGL
Aluminium Rainscreen System
GENERAL
DESCRIPTION 
The system comprises 3103H14 alloy cassette panels, post coated with
either polyester paint, or J57S alloy, post coated by anodising, 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 are independently tested and are also compliant with the 'Standard
for Ventilated Facades' as produced by the Centre for Window and Cladding
Technology at Bath University.
ALUMINIUM
3103H14 / J57S aluminium sheeting are structurally- strong aluminium
alloys in 2 or 3mm thickness and have good flatness and structural performance
under imposed loadings. A wide variety of sheet widths and lengths is
readily available in mill finish and this aids when projects have a
wide colour mix or small quantities. CGL has developed extensive expertise
in fabricating cassettes , cappings, curved details, and louvres from
these materials and takes full responsibility for designing the structural
attachment and stiffening of the panels.
FINISH
Polyester powder coating is applied by Interpon or Synthapulvin approved
applicators to BS6496. Anodising is carried out by approved applicators
to BS 1615 or 3987
CGL SS3
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
25 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..
