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!
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 maintaining natural
lighting and visibility, RPG introduces Clearsorber™Panel, a
micro perforated acrylic or polycarbonate panel, If
the perforations in a Helmholtz resonator are made sub-millimetre in
diameter, they are comparable to the thickness of a boundary layer of
Air. As sound passes through these micro perforations, sound
absorption will occur due to viscous boundary layer effects in the
perforations, when an air cavity is provided between the
Clearsorber™Panel and the vision glass. It is then
possible to achieve sound absorption without 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™Panel offers an acoustical solution
when a clear absorber is required.
Absorption
Clearsorber™ provides absorption, because the microperforated
panel, when spaced from a transparent or non-transparent reflective
surface, offers high viscous losses when air passes through the
surface. The Clearsorber™ is inherently damped and does not
require porous absorption in the cavity between the
Clearsorber™ and the reflecting wall behind it.
Installation
The Clearsorber™ is simply hung or fastened in front of a
reflective surface. It can also be hung in free space, provided that a
Clearsorber™ panel is spaced on either side of a
non-perforated transparent panel. In this mounting, both sides of the
panel are absorptive. Many shapes and configurations are possible.
