Groove

Timber acoustic panels for ceilings and walls


Groove timber acoustic panels give a high performance, sound absorbing surface with extensive finish options including HPL, real wood veneers, melamine, and RAL matched paint. The distance between the Grooves can be altered with smaller widths generally increasing acoustic performance.

We provide a full joinery service as well as acoustic advice so the panels can be well integrated in to the space with all ancillary items matched to provide continuity across the veneers.

Drawings and samples will be provided on request

How the panels absorb sound

As well as the linear slits in the face, Groove panels have large cutouts in the the rear which meet with the slits in the front, creating a perforated panel. These perforations, combined with a cavity behind the panel create resonance, due to the air in the cavity which acting like a spring. In combination with damping to remove sound energy, typically provided by a layer of mineral fibre in the cavity, this makes a Helmholtz absorber.
Changing the perforation pattern (in this case by selecting the width between the slits) alters the acoustic performance. Differences in the cavity depth and absorbent material in the void also have consequences.


Acoustic performance


Typical performance of Class C for Groove 12 example

sound absorption

Blue line - is Groove 12 with 100mm mineral fibre behind the panel.
NRC = 0.95
αW = 0.65 (class C)

Grey line - Groove 12 with 50mm mineral fibre behind.
NRC = 0.95
αW = 0.60 (class C)

(Tested to EN ISO 354:2003)

Coloured MDF core boards

A coloured MDF core board can be used to either blend better with darker finishes or to create dramatic contrast to highlight lines. It also hides the holes in the Grooves where the rear perforations meet.


Acoustic panel sizes

Wall panels - 198 x 2400 x 19mm (max 3000mm length)

Ceiling tiles - 600 x 600 x 19mm or 600 x 1200 x 19mm


Pattern variations (as pictured right)

Altering the distance between the Grooves in the panels creates differences in aesthetics and acoustic performance, generally, the closer the Groove, the higher the acoustic performance.


Header and footer Linear panels Above: Example 'Header and Footer' skirtings.

'Header and footer' skirtings

We have a range of skirting details or you can design your own to give an extra finishing detail to the panels.

Veneers, laminates and lacquers

We can source almost any veneers to face the panels; clear, tinted or full colour lacquers can be factory applied; or laminates used to customise the appearance.

Suspended ceilings

For ceilings, the same approach can be taken and applied to a suspended system or you can use our ceiling tile version, which is easily removable and acts to conceal a standard grid system.


Installation


Wall panel installation

Groove acoustic panels are typically installed on to battens in a simple tongue and Groove fashion to create a seamless finish. The cavity should include a sound absorbing mineral fibre or foam which will increase the acoustic performance. Panels can be mounted either with the Grooves running horizontally or vertically.
