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.

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.

Our design team are on-hand to provide details and guidance, from specification to completion.

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.

For further details, contact us.

Q.  Are you able to provide typical details and specification guidance for your systems?

A.   Sure. Contact us and our designers can look in to your requirements.


Q.  How do we match finishes across the project?

A.   For HPL finishes in solid colour, We can provide references for joiners to order sheets. Edge band matching is also available and we can provide RAL references.

A.   For HPL finishes in timber effect, We can provide references for joiners to order sheets. Edge band matching is also available.

A.   For veneer finishes we can provide samples for joiners to match.
On special request and with minimum orders we coordinate between joiners and veneer supplier for very precise matching across the project. Contact us for details about this.

A.   If you already have a finish selected, contact us and we can advise on the feasibility of a suitable match.


Q.  Can you also supply ancillary parts to match the timber acoustic panels?

A.  Yes. We can offer flat panelling to match the veneer of the acoustic panels, edge trims, and many other extras. You can design them yourself, too. See Bespoke section or email us for details.


Q.  What size are the cupboard doors?

A.   Made to measure with maximum 3000mm x 600mm wide. Acoustic doors guide available here.



Q.  How do I obtain a quotation?

A.  (When our product is clearly specified)

Assuming that our products have been specified on the project, we would require the specification, relevant drawings and BOQ.
Typically perforated panels are made to measure so we likely require a way to check sizes.

A.   (Budget costs)
 
We might typically need to ask:
-   Which of the perforation patterns has been selected?
-   What would the quantity be and can we asses panel sizes?
-   Is there a specific acoustic requirement?
-   If for ceilings, do the panels need to be fully demountable, or can access be localised?
-   Will the finish be veneer with oil / veneer with lacquer / HPL (most cost effective) / Birch ply (P16-C only)?
-   Do the panels need to be fire rated?
-   Are drawings available which show the area?
-   We will require a project reference and location.


Q.  What is the lead time?

A.  Typically 5-7 weeks from order unless made to measure panels are required and information is missing.
In that case 5-7 weeks from final confirmations.


Q.  Do minimum order quantities apply?

A.  Typically around 30m2


Q.  Where as a main contractor do we buy the products from?

A.  Either from us to install yourselves, an approved installer, or through the procurement package of designated installers.



Q.  What ceiling options do we have?

A.  Microperforated/Nanoperforated:

-   T&G planks (access panels may be required)
-   Concealed T-grid (demountable)

A.  P16-C (larger perforations):

-   Bespoke panel sizes fixed to MF grid (access panels may be required)
-   Concealed T-grid (demountable)


Q.  How do we address light fittings and services?

A.   We have typical details which cover most situations. If not, this can be addressed during the design process.



Q.  Do you provide installation services or have recommended installers?

A.   We do not install ourselves. We can suggest approved installers or provide installation guides to your designated installers.


Q.  How big are the panels?

A.   This varies depending on the design. Check relevant datasheet for maximum sizes.


Q.  Can you provide method statements/fixing details?

A.   Sure. Contact us for details.
