PROSONIC FG ACOUSTIC PANELS have a
Advantages
rigid, acoustic-rated fibreglass core with a
class 1 fabric covering as standard,
available in a wide selection of colours.
(Class 0 fabric available on request at
additional cost.)
 Easy installation
These panels are an efficient, durable,
cost-effective
solution
for
reducing
excessive reverberation in large spaces.
 Class 0 fire rated core
Various fixings are available (see p.2) and
units can also be custom made with hooks
for easy ceiling mounts, wire hangers or
split battens for wall mounting which is
ideal if you require them to be removable.
 Various mounting/fixing options
 Standard and custom sizes
 Edge profile options – see below
 Choose shape from rectangle, square,
circle, triangle, parallelogram
 Wide colour range
 25mm–100mm thick
 Class A absorber (except 25mm-thick
which is Class D)

When ordering panels,
please advise us if you
need fixings. Panels are
supplied without fixings
unless specifically
requested. Certain types
need to be specified in
advance. There will be an
additional cost for
supplying various clips,

Standard Surface Mount Timber Split Battens (picture above left)
For wall mounting, a split batten is fixed to the wall. The acoustic panel is
simply lowered in place. This system allows easy removal and provides an
additional airspace behind the panel for improved acoustic absorption.
(This option is available for panels of 25mm or thicker.)
Aluminium Batten (picture left)
This is a similar method but much thinner. It leaves virtually no gap
between the panel and the wall (approx. 3mm).
This system is available for panels 25mm or thicker.
Please contact us for further details.
Wall Spikes – Metal impaling clips are screwed into the wall. Adhesive is applied to the panel and the wall. The panel is
then offered up against the wall spikes and fixed in place.
This method does not allow easy removal of the panels.
For smaller panels spikes can be used without adhesive to allow removal; however, this does not provide a permanent
fix so would not be suitable in areas such as schools.

Hooks
Probably the easiest and most
versatile method of hanging the
panels from a ceiling, but not
generally recommended for
large, heavy panels
The hooks are simply screwed
into the panel which can then be
hung from chains.
The black backing scrim needs to
be cut away before these fixings
are screwed in. Contact our
technical department for method
and placement. This image is not
to scale and fixings should not be
near the panel edges.
Complete with a 1.5m
cable, gated hook end, and
wire loop. Fully adjustable
with the built in friction
clutch.
Please note: if using the
wire suspension systems
with spiral hooks, the
spiral hooks should be
200–300mm in from the
panel edges (panel size
dependent) to prevent
uneven load distribution
which, over time, could
cause the panels to
bend. (This will also help
to hide the wires from
sight.)
These fibreglass panels are
easy to install and can be made
in a wide range of custom sizes.
Fixing can be with optional
impaling clips or adhesive. Units
can also be supplied with a
wooden frame surround for
ceiling or wall mounting. (See
also above for split batten
fitting.)

product are measured by an independent, accredited NVLAP
facility according to the test methods as defined by ASTM C 423
Panels greater than 16 square feet must be carried by
a minimum of two people. Panels must never be set
down on fabric faces, only on the panel back.
