Timber slat acoustic panels are strips of real wood fixed over a felt backing, with a small gap between each slat. Sound passes through the gaps and is absorbed by the felt behind. From the room, it reads as joinery: warm, grained and architectural. The acoustics are hidden in the detail. If your interior uses wood, stone and planting, and a fabric panel would feel out of place, this is the product to look at.

How slat panels absorb sound

Wood on its own reflects sound. The absorption comes from the felt, and the gaps are what let sound reach it. That makes the spacing an acoustic decision as much as a visual one. Wider gaps and a bigger open area let more sound through to the felt, so absorption goes up, but the wall looks less solid. Narrow gaps look more like a continuous timber wall, but less sound reaches the absorber. We balance the two for your room, not for a photograph.

Where timber slats work best

  • Reception areas and boardrooms: where the wall is part of the first impression.
  • Hotel lobbies and restaurants: natural materials and warmth. See hotels.
  • Residential and home cinemas: a joinery finish that reads as decor. See residential.
  • Planted, natural-material interiors: alongside stone and greenery.

The advantages

  • It reads as joinery first and acoustic product second.
  • Slat width, spacing and finish can be varied, from fine battens to bold, wide slats.
  • Solid and veneered options exist, which changes the cost and look without changing the acoustic backing.
  • Most arrive pre-finished, so there is little on-site treatment.

The limits

  • Timber moves with humidity. Fixing and finish must suit the room, and it is a poor choice for high-moisture areas. For those, see industrial acoustic panels.
  • Absorption is tied to the slat gap and the felt, so you can't have a tight, near-solid timber look and high absorption at once.
  • Fire performance depends on the whole assembly, timber, felt and any finish. Ask for the Euroclass rating of the complete panel, and see our fire ratings guide.
  • The gaps show dust more than a flat surface, though an occasional vacuum is enough.

Timber slats vs acoustic wood panels

These two are often confused. Slat panels are separate timber strips fixed over felt, with visible gaps. Acoustic wood panels are continuous boards with perforations or grooves that let sound through. Slats give a stronger linear look. Perforated or grooved boards give a smoother, more uniform surface. We compare both against your look and your absorption target.

What to ask before you order

  1. Absorption class for the exact slat spacing and felt you are buying.
  2. Solid or veneer, and the finish or lacquer.
  3. Euroclass fire rating for the whole assembly.
  4. Humidity and temperature limits of the room.
  5. Whether slat spacing can be adjusted from the standard range.

Common questions

Can the timber be a veneer? Yes, veneer and solid options are both available.

Do they need sealing after installation? Most arrive pre-finished, but we confirm this per product.

Can I match existing joinery? Usually yes, by finish and species. We confirm the closest match before ordering.

See the wood in your light

Grain and colour look different in every room. Ask for samples, book a free survey, or see timber acoustic panels.

From first survey to final finish

One team handles all seven stages, the same way on every project, so you always know what happens next.

Acoustic Survey

A surveyor visits the site, or works from your drawings and photos when a visit isn't practical. Either way, the room, its surfaces and how it is used are recorded before any advice is given.

Acoustic Assessment

Reverberation, ambient noise and noise transfer are read against what the space is used for. The findings arrive as a written report with recommendations, yours to keep with no obligation to proceed.

Acoustic Design

Treatment is modelled against a reverberation target, then drawn up with panel positions, fixings and finishes. Nothing moves forward until you have approved the design.

Specification & Quotation

Every quotation comes with the specification behind it, listing products by type, quantity and finish with costs set out line by line. What is quoted is what the design calls for.

Acoustic Product Supply

Panels, baffles, ceilings and screens come from our Acoustic Solutions range and are supplied to the approved specification. What arrives on site matches what was designed.

Acoustic Installation

Our own engineers fit to the approved drawings, checking positions and fixings as they go. One team supplies and installs, so nothing is handed between contractors.

Acoustic Testing & Compliance

Optional: after fit-out the space can be measured again and compared with the original survey, so the improvement is measured rather than assumed. Results are reported against the relevant standards and the written record goes into your building file.
