ABSOL APL Metal Wall Panels are used primarily as sound absorbers in potentially
noisy environments such as gymnasiums, swimming pools, pump rooms and industrial
fabrication work areas. They are also
suitable as finished panels in offices, conference rooms and ceiling installations.
ABSOL APL Metal Wall Panels can be manufactured in aluminum to be used in high humidity
areas such as swimming pools or outside to control sound in areas such as performing
ABSOL APL Metal Wall Panels are modular units consisting of a perforated metal frame
surrounding an encapsulated acoustical absorbing fiberglass. The perforated metal
skin allows sound waves to enter the absorbing material where a portion is transformed
from sound energy to other forms of energy.

ABSOL API models are Acoustic Panels for industrial applications. The aim of developing
the Acoustic Panels is to combine acoustic performance with structural durability.
They are manufactured lightweight with firm surfaces, which are extremely strong
and resistant to damage.
All Acoustic Panels are supplied fully assembled, quick and easy to fit producing
a clean and neat interior decor presentation.
absol Acoustic Panels are superbly adaptable for straight walls and even ceilings,
and it edges can be shaped to fit almost any design.
ABSOL Acoustic Panel is a rigid composite comprising high density sound liner and
rock wool mineral fiber surfaces formed in to sandwiched panel and molded in to
a galvanized perforated sheet casing.
The Double skin panel constrution,outer face is of galvanized sheet steel of thickness
0.8* /1.0mm and inner
face is made of galvanized perforated sheet of thickness 0.8mm coating to Z-22 to
Z-27 to the standards JIS 3302 or BS 2989.
The acoustic infill material is of fiberglass with 24kg I mt3 density of thickness
25mm and rock wool with desity
48kg / mt3,of thickness 50mm formed in a sandwiched panel in compressed form.
The attenuation material used is of suitable for vermin –proof, rot-proof
and non-combustible, when tested to BS 476 : Side flashings for extreme ends of
Panel installation is constructed from galvanized sheet steel of thickness
These Acoustic Panels are designed to provide an ideal acoustic performance where
acoustic environment is as important as is prestigious appearance, All Acoustic
Panels are internally lined, and attenuation material standards are confirmed to
NFPA 90 and UL
The Acoustic panel's rear face is constructed from galvanized sheet, with pre punched
holes, of thickness 1.0*nnnn, which acts as an additional noise and vapor barrier
The exposed face is made of perforated sheet of thickness 0.7*mm and in powder coated
The external casing and the internal stiffeners are made of galvanized steel of
The acoustic infill material is of fiberglass with 24kg density of thickness 25mm
and mineral fiber rockwool with density 48kg formed in a sandwiched panel.

For Studios, Hotels and Theater Applications
APS models are Acoustic Panels for Studio and Hotel applications. They are manufactured
lightweight with firm surfaces, which are extremely strong and resistant to damage.
The front and exposed sides of standard Acoustic Panels are faced with a fabric
which is 50% viscose, 50% wool plain weave selected specially for acoustic performance
with flameproof characteristics.
The acoustic infill material is of sound liner with 24kg density of thickness 25mm
and mineral fiber rockwool with density 48kg formed in a sandwiched panel.
Fittings with 'T' Shaped wood channel along each vertical edge strengthens the Panel
Acoustic Panels are supplied fully assembled and careful attention is paid to all
the constituent parts.
Acoustic panels are ideal products where the acoustic environment is as important
as is prestigious appearance.
They meet both the acoustic performance and structural durability well within the
APS Panels are developed to provide interior design, with a superior acoustic panel
system. The standard range of fabrics has been selected specifically for high quality
appearance, durability and comprises to match any type of color and interior.
APS Panels are superbly adaptable for straight walls, curved wall, cascades and
even ceilings. Its edges can be shaped to fit almost any design.
Safety The attenuation material used is of suitable for vermin -proof, rot-proof
Easy To Install
Standard size AP Acoustic panels are 1.2 meters hight with 1.2 meters width and
50mm thick. Their light weight construction allows them to be moved around, aligned
and fixed with the minimum effort. Panels can be supplied in a combination of shapes
and sizes to suit individual projects. Alternatively panels can be made to any size
for fine adjustment as per site requirements.
The fixing method chosen for AP will depend on the performance intended by the individual
site application and its installation.
Acoustic environment is a key element in studio design and achievement of the appropriate
acoustic characteristics is essential if the studio is to function successfully.
ABSOLoffers a complete total package service including initial design study, acoustic
advice, project planning and management for equipment specification, supply,
Model APS are wall panels, which not only looks good but also has the sound
absorption characteristics needed for the optimum acoustic environment in offices,
reception areas, restaurants, banks, and studios.
It is highly resistant to damage, which often causes surface indentions, which detract
from the perfect wall panel visual effect. APS firm surface also allows it
to be used for art or photo displays.

Noise Reduction - The free field noise reduction of an acoustic panel is the difference,
in decibels, between the sound pressure level by the noise generating source and
radiated sound power levels, by the walls and the surrounding structure, measured
at actual levels.
Acoustic Panels Test Method
The sound power levels have been derived based on Test methods used are in accordance
with 1987 ASHRAE HVAC Systems and applications Hand Book Chapter 52, Page 52.7.
Accuracy: This is a prediction method based on an accepted method, which has demonstrated
satisfactory results in field applications. However field test results may generate
sound pressure levels which differ from these predicted values, as the current state
of the art in determining sound power varies in accuracy from 2 dB in mid range
250 to 4K Hz bands, 3 to 4 dB in 125 and 8K Hz bands and up to 6 to 8 dB in 63 Hz
