Choosing an acoustic panel supplier as a trade buyer comes down to five checks: what documentation they can actually produce (not just claim), whether they'll send a real sample before you order, how tight their manufacturing tolerances are, how the goods are packaged and palletised for transit, and how quickly and clearly they communicate once you've placed an order. A supplier who is vague on any of these is a bigger risk than one whose answer is simply 'not yet'.
- Ask what documentation exists, not what's planned. A supplier who says 'certification is coming' is telling you it doesn't exist yet — treat that as the current state, not a near-term promise.
- Always get a physical sample before committing to a bulk order — colour, texture and edge finish vary between a spec sheet and the real panel.
- Ask about manufacturing tolerances, especially on width and length, since these affect installation and wastage at scale.
- Check how goods are packaged and palletised for export, and whether that packaging meets import requirements such as ISPM15 for wood packaging material.
- Test communication before you rely on it — ask a real question during the quoting stage and see how long a clear answer takes.
Documentation: ask what exists today, not what's coming
The single most useful question to ask any acoustic panel supplier is: which documents can you send me right now? Test reports, formaldehyde-emission declarations, timber-sourcing certificates and declarations of performance either exist for a specific product, or they don't. A supplier who answers with a timeline ('certification is in progress') is telling you the true answer is 'not yet' — which may still be an acceptable answer for your project, but only if you know it going in.
Where documentation doesn't yet exist, a credible supplier will say so plainly rather than imply it. See importing & compliance for how we handle this ourselves — we publish exactly what we hold, and nothing we don't.
Sampling: see the real panel before you order at volume
Spec sheets and product photography can't fully convey colour, texture, grain or edge finish, all of which vary between a rendering and a production run. Before committing to a bulk order, request a physical sample of the exact decor and build-up you intend to buy — not a similar one. A supplier reluctant to send a sample, or one that only offers stock photography in its place, is a signal worth weighing.
Manufacturing tolerances
Ask what tolerance the supplier manufactures to on panel width and length. Small variances compound across a large installation or a full pallet run, affecting how panels butt together and how much wastage to allow for on a job. A supplier who can quote a tolerance figure, even a wide one, is giving you more to plan against than one who can't answer the question at all.
Packaging and palletisation
How panels are packaged and palletised affects both damage risk in transit and how efficiently a truck or container is loaded. Ask for the pallet configuration (panels per pallet, base layout, whether double-stacking is standard) and whether wood packaging material used for export meets ISPM15 requirements, which is a standard import requirement for wood packaging entering the UK. See pallets and loading for how we publish this ourselves.
Communication and lead times
A supplier's communication style at the quoting stage is a reasonable preview of how they'll behave once you have an order and something needs resolving. Ask a specific, slightly awkward question early — about a dimension, a lead time, or a document — and see how quickly and how directly it gets answered. See lead times & delivery for how transit-time expectations should be set and confirmed per order, not left as a vague promise.
Frequently asked questions
Should I avoid a supplier that has no test reports yet?
Not necessarily — it depends on your project's requirements. What matters is that the supplier tells you clearly what is and isn't evidenced, so you can decide whether that's acceptable for your use case, rather than discovering a gap after you've ordered.
How many samples should I request before ordering at volume?
At minimum, one sample of the exact decor and build-up you plan to buy — not a similar finish. For a large or specification-critical order, ask whether a small trial batch from the actual production run is available before committing to full volume.
What packaging standard should wood packaging meet for UK import?
Wood packaging material (pallets, crates, dunnage) used in international trade generally needs to meet ISPM15 treatment and marking requirements. Ask your supplier to confirm their packaging is ISPM15-compliant as part of your due diligence.
Specifying acoustic panels?
Order finishes to see and hear, model the room with the reverberation calculator, or send us the spaces and targets for panel selection and a quote. We publish no performance figure we cannot evidence — what that means for your project.
