Acoustic GRG have been manufacturing and installing premium room acoustics products in the UK and Europe for the last 25 years.
From our 27,000 sq ft workshop in Kent we produce and supply the full RPG range of acoustic wall and ceiling panels. We also distribute and resell Clipso and Fabricmate stretch fabric solutions, Green Glue, Spigo and Lambri acoustic wood systems as well as Camira acoustic fabrics and seamless acoustic plaster.
Architects, contractors and acoustic consultants rely on our ability to manufacture and install our products to the highest standards and tolerances. Whether it's for an office development, a recording studio, a restaurant, or to comply with BB93 for education and schools, we can help with any acoustic requirement.
Please don't hesitate to give us a call on 01303 230944 for more information. You can now find us on Twitter, Pinterest, Instagram, LinkedIn and Facebook too!
Clearsorber™Sheet is based on new patented technology, utilising
microperforations in a transparent or translucent sheet. When the Clearsorber™Sheet is spaced off
the vision glass, these microperforations produce significant viscous
losses, providing the necessary sound absorption. Applications
are only limited by the imagination.
The Future is Clear!
Problem
Projects designed with extensive use of glass surfaces can produce
strong interfering reflections and excessive reverberation, which
create an uncomfortably loud ambiance, causing fatigue, and corrupting
speech intelligibility
Solution
To address these acoustical problems, while mainting natural lighting
and visibility, RPG introduces Clearsorber™Sheet, made from
microperforated polycarbonate. If the perforations in a helmholtz
resonator are made sub-millimeter in diameter, they are comparable to
the thickness of a boundary layer of air. As sound passes through
these microperforations, sound absorption will occur due to viscous
boundary layer effects in the perforations, as long as an air cavity is
provided between the Clearsorber™ Sheet and the vision
glass. It is then possible to achieve sound absorption with out
the need for additional porous material in the cavity behind the
microperforated sheet, thus allowing the panel to be transparent or
translucent. Therefore, the ClearSorber™ Sheet offers an
acoustical solution when a clear sound absorber is required.
Absorption
The Graph illustrates the sound absorption coefficient for a 1mm
thickness (t), 0.5mm hole diameter (d), 5mm hole spacing (b) and
various distanced (D) from the glass.
SPECIFICATIONS
Material: Polycarbonate
Sizes: 2500mm x 1250mm
Thickness: 1mm
Weight:0.26 lbs/sf
Colour: Clear
Installation
Clearsorber™Sheets can be mounted or suspended with exposed
decorative hardware or formed into a panel spaced off a non-perforated
sheet with acrylic borders.
Features
Microperforated
High Sound Absorption
Transparent
Moisture, bacteria, and fungi resistant
UVstable
Class A Fire Rating
Easy to install
Benefits
Patented sub-millimeter microperforation tecnology in a transparent
sheet provides
sound absorption
Eliminates potential danger from particulates
High sound absorption is a result of viscous boundary layer effects in
the perforations,
when a rear air cavity is provided between the Clearsorber™ Foil and the
vision glass
Because the microperforations provide sound absorption without the need
for a backing porous material, the Clearsorber™Sheet can be made
transparent, allowing natural lighting and visibility from a clear
absorber
The 1mm sheet is resistant to moisture, bacteria,and fungi and so can be
used in place of
traditional fabric upholstered systems
UVstability insures the panels will not discolor nor decompose over time
Polycarbonate can be used in those facilities requiring a Class A/1
rating
Quick and easy installation saves time and money
Panels can be simply mounted or hung with decorative hardware selected
by the
architect. Sealed panels can be fabricated from one layer of
Clearsorber™, air cavity and non perforated sheet with acrylic
borders
