ClearSorber HoneyComb™
transparent absorbing rigid panel
Clearsorber™Honeycomb is a rigid composite panel, consisting of two microperforated layers with a clear
honeycomb core.
Sound absorption is provided by a patented technology, utilizing
microperforations in the outer layers. The Future is Clear!
Problem
Absorptive materials are typically opaque and when natural or artificial lighting is desired along with acoustical absorption, choices are limited.
Solution
To address this architectural acoustic problem, RPG introduces Clearsorber Honeycomb, a composite panel consisting of two layers or 1mm microperforated polycarbonate sheet, with a clear honeycomb core. The sub-millimeter perforations provide Helmholtz resonant sound absorption. As sound passes through these microperforations, which are comparable to the thickness of a boundary layer of air, sound absorption occurs due to viscous boundary layer effects in the perforations. The frequency of maximum sound absorption is decreased as the air cavity behind the composite panels is increased. The Clearsorber Honeycomb panel is also rigid and can be suspended, parallel to the floor, without significant bending, thus, sound absorption can now be provided along with natural or artificial lighting.
Absorptionabsorption co-efficient for three cavity depths. D measured to the face of the Honeycomb panel, therefore D=50 indicated a cavity depth of 32mm
Installation
Clearsorber™ Honeycomb panels can be built into framing, hung from ceilings, laid into a T-Bar or used as lighting diffusors. For sound isolation and attentuation, one side is the perforated side and the other side is solid. For this application, we recommend the 35mm panel thickness, which offers 19db of isolation.

Benefits
Patented sub-millimeter microperforation technology 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™ Honeycomb and the vision glass
Because the microperforations provide sound absorption without the need for a backing porous material,the Honeycomb™ offers a translucent surface that allows natural and artificial lighting and visibility
The Honeycomb™ is resistant to moisture, bacteria, and fungi and so can be used in place of
traditional fabric upholstered systems
UV stability insures the panels will not discolour nor decompose over time
Polycarbonate can be used in those facilities requiring a Class A/1 rating
Can be applied to wall surfaces with standoffs, suspended, laid into T-Bar grids or incorporated into extruded aluminium framing.
