Specifying acoustic wall panels for a commercial fit-out means turning a vague echo complaint into a signed-off schedule: room list, finish, size format, fixing method, and fire paperwork, all before the contractor lifts a panel. This guide walks through the brief-to-installation sequence for 2026 fit-out projects.
- Specifying acoustic wall panels starts with a room-by-room brief, not a finish choice - measure wall area first.
- Akustiq UK panels ship in 240cm and 300cm formats; match format to ceiling height before ordering, not after.
- Order samples before committing budget - lighting in a reception area reads finishes differently than a showroom.
- Skip fire compliance checks on public-facing commercial walls and the fit-out stalls at building control. Buy samples, then specify.
Why this matters
A fit-out spec that skips the acoustic brief gets revisited mid-install, and that costs programme time, not just money. Open-plan offices, reception areas, and breakout rooms all reflect sound differently, so the same finish that quiets a boardroom can leave a lobby echoing.
Acoustic wood panels solve two problems at once on a commercial job: they cut reverberation with a felt backing, and they carry a real wood veneer finish that reads as premium fit-out rather than acoustic foam. Getting the black oak wall panel or a lighter oak finish onto the spec sheet early avoids a scramble when the M&E contractor asks for wall build-ups in week three.
What you'll need
- Floor plan with wall elevations and net wall area per room
- A room-by-room use list (reception, meeting room, breakout, corridor)
- Ceiling height measurements to decide between the 240cm and 300cm panel formats
- Sample panels in the finishes under consideration
- Fixing method confirmed against substrate (plasterboard, concrete, steel frame, or stud wall)
- Budget sign-off and a fit-out programme slot for panel delivery and installation
- Panel adhesive or mechanical fixings, plus end pieces and trims for clean edges
The steps
1. Define the acoustic problem room by room
Walk the floor plan and flag which rooms actually need acoustic treatment versus which just need a decorative finish. A reception with hard flooring and a glazed frontage reflects sound very differently to a carpeted breakout room, so the felt-backed panel does more work in the reception. Write down wall area in square metres for each flagged room before you touch a product page. The common mistake here is speccing acoustic panels uniformly across a floor when only two of six rooms have a genuine echo problem, which inflates the budget for no acoustic gain.
2. Set the specification brief
Turn the room list into a brief: finish, quantity per room, size format, and fixing method. This is the document the architect or specifier signs off before procurement starts. A tight brief for 2026 fit-outs names the exact wall elevation, not just "reception wall," because panel counts change with door and window openings. Skipping this step is why fit-outs order too few panels and then wait on a second delivery mid-programme.
3. Choose finish and size format against ceiling height
Akustiq UK panels come in 240cm and 300cm lengths, and matching the format to ceiling height cuts waste and visible joins. A standard 2.4m commercial ceiling suits the shorter format with almost no cutting; anything taller benefits from the 300cm board to avoid a horizontal seam at eye level. Darker finishes such as black oak or smoked oak read well in low-light corridors, while natural oak or grey oak keep a reception brighter. Get this wrong and you end up with visible offcuts on a feature wall that was meant to be the first thing visitors see.
4. Order samples before you commit
Sample panels cost a fraction of a full order and remove the single biggest specification risk: a finish that looks different under LED downlights than it did on screen. Architects and specifiers working across multiple sites use samples to lock a finish across a portfolio before a single full panel ships, a process covered in the architect and specifier buying guide. Order at least two finishes per room type if the client hasn't already picked one; the common mistake is speccing from a swatch and finding the real veneer reads warmer or cooler once it's on the wall.
5. Confirm fixing method and fire compliance
Fixing method depends on the substrate: plasterboard, concrete, or steel frame each need a different approach, and getting this wrong means panels that come loose within a year. Public-facing commercial spaces also carry fire compliance requirements that residential jobs don't, so check building control expectations for the space before finalising the spec, detailed further in the fire-rated acoustic panel guide. Missing this step is the single most common reason a commercial fit-out spec bounces back from building control in 2026.
6. Calculate quantity and order fixings
Measure each flagged wall's net area, divide by panel coverage for your chosen format, and round up for cuts around doors, sockets, and corners. Order end pieces and trims alongside the main panels so edges finish cleanly rather than with a raw cut visible at the join. High-tack panel glue works for most stud and plasterboard fixings; steel frame and concrete substrates usually need mechanical fixings instead. Underestimating quantity by even 5% on a large open-plan floor means a delayed second order that stalls the install crew.
7. Slot the install into the fit-out programme
Panel installation happens after first-fix electrics and before final decoration, so confirm that window with the programme manager early. Panels need a stable, dry substrate, so scheduling install before plastering has fully cured causes adhesion problems later. Build in a day for snagging once the main install is done, particularly around door frames and light switches where panels need precise cuts.
8. Sign off against the original brief
Walk the finished rooms against the brief from step two: correct finish, correct format, no visible gaps, edges finished with trims. This is also the point to photograph the install for future maintenance reference, since replacement panels years later need to match the original finish batch as closely as possible.
Troubleshooting
- Panels ordered before wall squareness was checked - out-of-square walls create visible wedge gaps; measure diagonals before finalising quantity.
- Wrong size format for ceiling height - a 300cm panel on a 2.4m ceiling wastes 60cm per board in cutting; recalculate format against actual room height, not a standard assumption.
- No samples ordered before full commitment - finishes shift under different lighting; always order the £4.45 sample panels for finishes under real consideration.
- Fixing method mismatched to substrate - adhesive alone won't hold on some steel frame builds; confirm mechanical fixing compatibility with the substrate before install day.
- Fire compliance overlooked - public-facing commercial spaces often need documentation building control will ask for; check this before the panels are ordered, not after.
- Quantity underestimated around openings - doors, sockets, and corner returns eat more panel than a flat wall-area calculation suggests; add a buffer before finalising the order.

For reception areas or breakout zones that want a decorative accent alongside the acoustic slat panels, handcrafted 3D wall panels work as a feature wall element without adding to the acoustic wall count.
What to do next
Once the brief and finish are locked, the next document to build is the fire compliance file for the space if it's public-facing, then the fixings order. Get the sample panels moving in week one of the programme; everything else in the spec depends on that finish decision holding.
FAQ
How do you specify acoustic wall panels for a commercial fit-out?
Start with a room-by-room brief that names wall area, finish, size format, and fixing method before ordering anything. Confirm fire compliance for public-facing rooms and order samples before committing full budget in 2026.
What size acoustic wall panels are available for commercial jobs?
Akustiq UK panels come in 240cm and 300cm lengths. Match the format to ceiling height: 240cm suits standard 2.4m commercial ceilings, 300cm suits taller floor-to-ceiling walls.
Do commercial fit-outs need fire-rated acoustic panels?
Public-facing commercial spaces typically carry fire compliance requirements that residential rooms don't. Check building control expectations for the specific space before finalising the panel spec.
How much does it cost to sample acoustic wall panel finishes?
Sample panels cost £4.45 per finish as of 2026, a small outlay against the risk of ordering a full run in the wrong tone. Order at least two finishes per room type before committing.
Should acoustic panels be fixed with glue or mechanical fixings?
That depends on the substrate: plasterboard and stud walls often take adhesive fixing, while steel frame and concrete substrates usually need mechanical fixings. Confirm compatibility before ordering fixings.
How many acoustic wall panels does a commercial room need?
Divide net wall area in square metres by the coverage of your chosen panel format, then round up for cuts around doors and sockets. Add a buffer of roughly 5% for openings and corner returns.
What's the difference between acoustic panels and decorative wall panels?
Acoustic wall panels carry a felt backing that reduces reverberation, while decorative 3D panels add texture without the acoustic layer. Commercial fit-outs often use acoustic panels on problem walls and decorative panels as a feature accent elsewhere.
When should acoustic panels be installed in a fit-out programme?
Install after first-fix electrics and before final decoration, once the substrate is dry and stable. Scheduling before plaster has cured risks adhesion problems later in the programme.
One last thing
The fit-outs that go smoothest in 2026 are the ones where samples get ordered in week one, not week six - a £4.45 sample panel is cheap insurance against a full room order in the wrong finish.
