Timber acoustic panels for ceilings and walls

Perforated acoustic panels enable a wide range of options to control reverberation in many types of space. There are several perforation patterns from large to Nanoperforated, and bespoke designs on request. Different edge details and panel sizes provide installation options for walls, ceiling, and now also doors.
Finishes include wood veneers, timber effect HPL (high pressure laminate), Birch plywood and solid colour HPL.

Drawings and samples will be provided on request.

How the panels absorb sound

The perforations, combined with a cavity behind the panel create resonance, due to the air in the cavity which acts like a spring. In combination with damping, typically provided by a layer of mineral fibre in the cavity, to reduce sound energy. This is known as a Helmholtz absorber.
Typically, increasing the open area created by the perforations increases absorption.

αW = 0.70 (class C)

Cupboard door with 500mm cavity (simulated filled).
αW = 0.70 (class C)

Cupboard door with 500mm cavity (Empty).
αW = 0.55 (class D)

Acoustic cupboard doors and furniture panels


It is now possible to have instead of acoustic walls - made to measure acoustic cupboards, sliding doors, and folding partitions which match the perforated wall panels.
Not visible externally, the core of the panels have reinforced core boards which create rigid frames and allow for many types of hinges and handles.


Further design options


We aim to offer a solution with continuity across the design. This includes offering reflective panels to match the acoustic ones, fire rated acoustic doors and cupboards, flexible boards to form curves, veneer coordination with other trades, and finish matching.


Panel options


Environment

FSC sourced materials available on request

Fire performance

When specified Class O (Euro Class B) components are used.

Face finishes

HPL laminates are available in over 500 different finishes, including timber effect and solid colours, and offer a durable, modern aesthetic.

Veneers give the most natural finish, and can be matched to other joinery items. They are generally supplied with a matt lacquer or coloured oil finish.

For full selection see Timber finishes page.

Installation


Wall panel installation

Typically mounted on a wooden frame with invisible 45° split battens. The wooden frame is filled with sound absorbing mineral wool (e.g. Rockwool at 45kg/m3). We advise you to leave a space of 2.5 mm per meter in height and width around the panels to allow expansion.

Left: Typical installation with panels on 50mm softwood battens, black tissue to the rear of the panels and 50mm of mineral fibre in the cavity.


Suspended ceilings

For ceilings, we can supply in T&G planks for mounting to MF metal framing. For panels with larger holes, full sheets can be mounted to an MF frame.

We can also supply panels with profile for hidden T-grid suspension.
