Acoustic sliding panels are the fit-out item that a procurement team is least able to inspect and most likely to be asked about after handover. Nobody can hear a sound test on the loading dock, and nobody can prove a performance claim by looking at a panel face. So the value a procurement team adds on acoustic sliding panels is not in the purchase order; it is in the documentation that sits behind the purchase order. Get that documentation right and the product is auditable. Get it wrong, and the building has an expensive sliding wall whose acoustic behaviour nobody can explain to the client, the consultant or the end user.

Start by recording what the listing does not say

This is not a criticism of the product; it is the nature of configurable listings. A configurable catalogue entry tells you the panel system exists, that finish, layout and dimensions can be specified per space, and that sizing is made to measure. It does not tell you the acoustic rating of the assembled wall, the track and hardware set, or the panel build-up. It also carries an explicit instruction to confirm project requirements and acoustic performance for the selected configuration. A procurement team that treats the catalogue entry as a specification has documented nothing at all.

So the first document in the file is a statement of what has still to be established for your project, written before you request a quotation: the performance the room requires, the configuration proposed, and the gap between them. Everything below is how you close that gap on paper.

Record the acoustic requirement as the project's own number

Do not let the supplier set the target. Take the requirement from the project: the acoustic brief, the consultant's note, or the operator's written standard for that room type. Record it with the source and the date — for example, the reverberation or sound-insulation behaviour the space is expected to achieve when the panels are closed, and what is acceptable when they are open. Then record the panel system's stated performance for the specific configuration you are buying, not for the range in general.

Where the two do not obviously line up, ask the supplier to state, in writing, what the assembled system delivers and on what basis: which test or calculation method, on what build-up, with what assumptions about seals, perimeter detailing and the flanking paths around the track. An unanswered question here is not a gap in the paperwork; it is the risk itself, priced into your order and discovered after the wall is installed. If the supplier cannot state it, record that too, and escalate it as a design risk rather than a commercial one.

Specify the build-up, not the product name

"Acoustic sliding panel" describes a function, not a construction. The file should hold, per panel: the core or infill, its thickness and how it is contained; the facing material and its thickness; the edge detail, because a panel's acoustic performance is usually lost at its edges and not through its centre; the face finish and the sheen; and the total assembled thickness of the closed wall, since that drives pocket size, track position and structural loads.

Related systems in the same catalogue make the point: fixed acoustic wall panels and sliding acoustic panels can share a face finish while behaving completely differently as a wall, and the reason is always the build-up and the joint, not the visible surface. Record the two as different systems with different evidence.

Document the track, hardware and suspension as a separate scope

Sliding panels are only as good as what holds them. The order file needs its own record of the hardware: the track type and its mounting arrangement, the hangers and their load rating, the panel weight per hanger, the operating force expected, the lock or latch detail at the meeting stiles, and the ceiling or structural support the track is fixed to, with the party responsible for providing it.

Then record the interface decisions that determine whether the acoustic claim survives installation: what the perimeter seal is, how the head detail meets the structure above, how the vertical meeting stiles close, and whether panels are floor-guided or floating. Every one of those is a line someone has to build on site. If it is not on a drawing referenced by the order, it will be decided by whoever is on site that day.

Fix the layout and storage geometry before the panel schedule

Acoustic sliding walls are bought as a stack. Document the layout in the same terms the factory needs: total opening width, panel width and count, the stacking direction, the parking zone, and how the stack is retained when open. Record the panel schedule as a numbered drawing with each panel's size, face finish, edge detail and position, and have the client or architect sign it. A changed parking zone after production starts is one of the few changes on this product that cannot be absorbed quietly.

Finish references and the sample you approve

Because the panels present a large continuous face to the room, the finish reference is a whole-wall decision rather than a small one. Keep in the file the approved physical panel sample, its finish and sheen, the joint and shadow-line detail between panels, and the tolerance agreed for variation across a run. Approve the sample standing vertically, in the orientation it will be installed, under the room's lighting.

Where the wall also carries integrated services or lighting in the adjacent joinery, record how cables and drivers are routed through the moving elements and who owns them, because a sliding panel that also carries services is two scopes pretending to be one.

Use the project workflow so the record is created by the process

SANTERSON describes a project workflow running through consultation, design and planning, production, logistics, installation and after-sales, with custom and OEM work and door-to-door delivery. Those stages are the natural places for the documents to be produced and signed, so put them there: the requirement and configuration confirmation at design stage; the panel schedule and finish reference at planning; the acoustic basis for the chosen configuration before production; packing, inspection and handover at delivery. Confirm dimensions and the selected specification for your project before production begins, because on made-to-measure wall systems a measurement error cannot be corrected by returning goods.

Treat supplier service descriptions as claims to be verified for your project, not as commitments. Record in the file what the supplier states and what has actually been confirmed for your job in writing — lead time, delivery scope, who installs, who inspects on arrival, what after-sales covers for a moving wall system, and how a damaged panel is replaced and matched to the approved finish later.

The file a procurement team should be able to hand over

At handover, the acoustic sliding wall should have one folder containing: the acoustic requirement, with its source; the stated performance of the selected configuration and the basis given for it, including test method and assumptions about seals and flanking; the panel build-up and edge detail; the panel schedule, signed; the track, hanger and lock specification with load ratings; the interface details at head, jambs and meeting stiles, shown on a drawing; the approved finish sample and its tolerance; the measured opening record; the packing, inspection and handover record; and the after-sales scope for a moving system, including replacement and finish matching. If any one of those is missing, the risk on this item is undocumented — and undocumented acoustic risk is always found late, by someone who was never on the project team.
