Configuration
The standard louvre system can be supplied in
a modular format i.e. factory assembled in frames
or "site built" continuous. Irrespective of format
each opening will comprise a variety of the following
items.
1. Front louvre blades. There are three
commonly used profile blades which can be identified
by their vertical spacing - 60, 80 and 100mm.
The example above shows standard 80 and 100 blades.
The blades are supplied to site in long lengths,
typically of around 6.0m The blades join on metal
clips with a small gap for thermal expansion and
structural movement. The effect is of a continuous
appearance with hidden mullions and no visible
fixings.
2. Second and third pass louvre blades.
Each of the front louvre blades has a corresponding
set of rear blades which are, typically, up to
1 .25m long. These blades provide additional high
levels of weathering. They are either supplied
as factory assembled modules or loose for site
assembly.
3. Mullions. The mullion system is designed
for a complete knock-down louvre system. There
are 2 basic mullions - standard and extra. The
mullion type is selected according to wind load
requirements. The louvre blade mounting clips
are factory fitted to the mullions.
4. Infill. A comprehensive range of infill
media options is available to fit between the
mullions:
Bird guard - mill finish or coated aluminium
mesh.
Insect mesh - woven aluminium, stainless
steel or nylon mesh.
Blanking panels -
a. uninsulated: 1.5mm alloy sheet, mill finish
or coated.
b. insulated: 1.5mm outer sheet, 1.0mm inner,
mill finish or coated, infill to thermal or
acoustic specification.
5. Perimeter frames. Extruded or folded
to suit each application usually from 1.5mm aluminium,
colour coated as required. Supplied up to 6.0m
as a continuous single length.
6. Fixing cleats. Each louvre system is
supplied with 3mm mill finish aluminium fixing
cleats, complete with fixings to connect to the
mullions.
7. Misc. fixings, sealants. All mechanical
fixings required to assemble the louvres are automatically
included.
8. Maintenance. The standard louvre system
is designed to require minimal maintenance. However,
it is necessary that the blades be regularly cleaned
and inspected for damage.
