Acoustic Panels for Auditoriums: A Specification Guide

Auditoriums do not need a single named “auditorium panel” — they need large-area coverage planned around specific panel dimensions, batch color matching, and certification scope. BEIEN’s PET Acoustic Panel Sheets and Wood Slat panels each cover part of that job, with different sizes, thicknesses, and documented limits worth checking before you order.

What Makes Auditorium Specification Different From a Standard Room

A conference room order might run a few dozen panels in one color, installed once, on one wall type. An auditorium project is a different scale problem: hundreds of square meters, often split between rear and side walls, sometimes the ceiling, usually procured in phases as construction progresses. Three things matter more here than in a small-room order.
Color consistency across production batches matters because a 400-panel wall run over several weeks can drift in shade if the supplier isn’t controlling for it. Dimension planning matters because auditorium walls are rarely a clean multiple of a single panel size. Designers need to know the real sheet dimensions, not a rounded catalog number, before they lay out a cutting plan. Certification scope matters because auditoriums are public assembly spaces, and a fire or emissions document that covers one product configuration doesn’t automatically extend to another.
None of these are solved by picking a “premium” panel. They’re solved by getting exact numbers before the order is placed, which is the point of this guide.

PET Acoustic Panel Sheets: Specifications for Large-Area Runs

BEIEN’s PET Acoustic Panel Sheets are the more common starting point for auditorium wall and ceiling treatment, since they’re produced as flat sheet stock in a color range wide enough to support custom branding or architectural color schemes.

Two things in that table need a caveat before a designer uses them in a drawing set.
First, the 1220 × 2420 mm figure is the size shown in BEIEN’s 2026 catalog. Some BEIEN product pages list 1220 × 2440 mm for what appears to be the same sheet line. That’s a 20 mm difference per sheet length, small per unit but enough to throw off a cutting plan across a few hundred panels. Confirm the exact current dimension with BEIEN before finalizing a layout, rather than trusting either published figure in isolation.
Second, the EN 13501-1:2018 B-s2,d0 classification comes from a specific SGS test report (No. SHFS2403000289FF, issued by SGS-CSTC Standards Technical Services, Shanghai), and the tested sample was a 9 mm, 1700 g/m² board under model BN-002, not the full PET Acoustic Panel Sheet range. A 24 mm sheet in a different color has not been shown to carry the same classification unless a separate test confirms it. Ask for the report number and match it against your specified thickness before citing this classification in a fire-safety submission.

Planning Batch Color and Dimension Consistency Across a Large Order

For a project running several hundred panels in one specified color, three practical steps reduce the risk of a visible batch mismatch on installation day:

1. Request the color reference by BEIEN’s BP code, not a verbal description, and confirm whether Pantone or RAL matching is being used for that specific order.
2. Ask whether the full order quantity will be produced in a single production run or split across multiple runs, since split runs carry higher risk of shade drift.
3. Request a physical sample panel from the actual production batch — not a catalog swatch — before the full order ships, and sign off on it as the color reference for any dispute.
4. Confirm the exact sheet dimension (1220 × 2420 mm or 1220 × 2440 mm, per the discrepancy noted above) in writing before your installer finalizes the cutting plan.

Compared to sourcing panels from multiple smaller local suppliers to cover a large auditorium run, consolidating the order with a single manufacturer reduces the number of separate production batches in play, though it doesn’t eliminate the need to confirm batch consistency within that single order.

Wood Slat Panels as an Alternative or Complementary System

Where the design calls for a wood-veneer finish on side walls or an acoustic feature wall behind the stage, BEIEN’s Panneaux acoustiques à lamelles de bois are a separate product line with their own specification set, not a finish option layered onto the PET sheet line above.

BEIEN holds an FSC Chain of Custody certificate (registration GFA-COC-008037, issued by GFA Certification GmbH, valid through 28 October 2029) whose published scope covers certain non-timber forest products, mouldings, other wood products, and wooden sound-absorbing boards. It’s worth confirming against your specific BN model before citing it in a sustainability submission.
The line also carries a CE Type Examination Certificate (DE/7552, issued by CSI S.p.A., referencing EN 15102:2007+A1:2011, valid through 10 June 2029). The certificate describes the product as a decorative wall covering under the model “BEIEN WALL PANEL.” If your auditorium design calls for wood slat panels on the ceiling rather than the wall, this certificate’s scope has not been confirmed as covering that application. Check with BEIEN before specifying it for overhead installation on that basis.
No published NRC/absorption data, per-panel weight, or fire test report is currently available for this wood slat construction. If your project requires those figures for a submittal package, request them directly and expect a “to be confirmed” answer if BEIEN hasn’t published them yet. That’s a gap in the documentation, not a hidden number being withheld.

Certification Scope, Summarized by Application

A separate note applies to a claim some readers may encounter elsewhere in BEIEN’s catalog: certain PET Slat Panel product pages reference an ASTM E84 Class B or EN 13501 B-s1,d0 fire rating. No public test report has been identified that verifies this specific claim for that product series, and it should not be relied on for an auditorium fire-safety submission until a matching report is provided.

Commercial Terms for Project-Scale Orders

Pricing for an auditorium-scale order is quotation-based and depends on panel type, dimensions, thickness, surface finish, fire-performance requirements, customization level, packaging, and shipping terms; there is no fixed per-square-meter list price to quote here without those specifics.
Minimum order quantity is inconsistent across BEIEN‘s own published pages: company history and customized-service pages state an MOQ of 50 panels, while individual product pages sometimes state 100. For an auditorium-scale project this is unlikely to be a binding constraint, but confirm which figure applies to your specific model before budgeting a small pilot order or sample run.
Standard production lead time is stated as approximately 7–15 working days depending on order quantity and customization. For a several-hundred-panel auditorium order, expect this to run toward the longer end, and confirm a firm date against your installation schedule rather than assuming the shorter figure applies by default.

FAQ

What’s the standard sheet size for BEIEN’s PET Acoustic Panel Sheets?

BEIEN’s 2026 catalog lists 1220 × 2420 mm. Some product pages list 1220 × 2440 mm for the same line. Confirm the current figure directly before finalizing a cutting plan.

 Does BEIEN’s fire classification cover all thicknesses of PET Acoustic Panel Sheets?

No. The EN 13501-1:2018 B-s2,d0 classification comes from a test on a 9 mm, model BN-002 sample only. It has not been shown to extend to other thicknesses or configurations without a separate test.

Can wood slat panels be installed on an auditorium ceiling under the existing CE certificate?

The CE certificate (DE/7552) describes the product as a decorative wall covering. Its scope for ceiling application has not been confirmed — check with BEIEN before specifying it on that basis.

What’s the minimum order quantity for an auditorium project?

BEIEN’s published MOQ figures are inconsistent — 50 panels on some pages, 100 on others. Confirm the figure for your specific product before ordering.

 How long does production take for a large auditorium order?

Standard lead time is stated as approximately 7–15 working days, with larger and more customized orders running toward the longer end. Confirm a firm date against your project schedule.

 Is absorption performance (NRC) data available for these panels?

Not in verified published form for either the PET Acoustic Panel Sheets or the Wood Slat panel line at this time. Request this data directly from BEIEN if your acoustic consultant needs it for a reverberation calculation.
