Acoustic Slat Wall Panels: Wood vs PET Specs Compared

Wood slat panels (BN-01–BN-05) pair MDF slats and 0.4–0.5mm veneer with an in-house PET acoustic backing; PET Slat Panels use 100% polyester fiber with no wood core. Catalog sizes overlap at 2400/2700/3000 × 605mm, 18/21mm thick, but certification scope, published density, and a site-wide dimension conflict change what each product can be specified for.

Two Different Cores Under the Same Slat Profile

The BN wood slat series builds from an MDF slat core, reported at approximately 760–800 kg/m³, faced with a wood veneer roughly 0.4–0.5mm thick. Behind the slat sits a PET acoustic backing produced in-house. The MDF component follows an E0-grade raw material policy per BEIEN’s documentation.
PET Slat Panels skip the MDF and veneer layers entirely. The slat itself is 100% polyester fiber, drawing on the same in-house PET felt production line that supplies the wood series’ backing. That difference matters for weight, moisture exposure, and machining — a veneered MDF slat behaves differently on-site than a felt-fiber slat — but BEIEN’s documentation doesn’t currently publish a per-panel or per-m² weight for either line, so any weight-based load calculation still needs to come from a direct factory confirmation rather than the catalog.

Spec and Dimension Comparison

What Each Certificate Actually Covers

BEIEN holds an FSC Chain of Custody certificate (GFA-COC-008037) issued by GFA Certification GmbH under FSC-STD-40-004, Version 3.1, valid from 29 October 2024 to 28 October 2029. Its published scope covers timber-based products, including wooden sound-absorbing boards — relevant to the BN wood slat line in principle, but the certificate doesn’t list every model by name, so the specific BN part number and order volume should be confirmed against the certificate scope before an FSC claim goes into a spec sheet.

The CE Type Examination Certificate (DE/7552), issued by CSI S.p.A. in Italy under EN 15102:2007+A1:2011, covers a product described as “BEIEN WALL PANEL” — a decorative wall covering. This is a wall-application certificate. Whether it extends to ceiling installations of the same slat product hasn’t been confirmed, so a ceiling spec built on this CE number is not yet supportable.

Here’s the edge case worth flagging directly: BEIEN’s only fire classification on file is an SGS test (report SHFS2403000289FF, EN 13501-1:2018, classification B-s2,d0) run on a flat 9mm PET board sample, model BN-002, at a density of 1700 g/m². That’s a board — not a slat panel of either material. Carrying a flat-board fire result over to a slat-format product, wood or PET, is exactly the kind of certificate-scope error this comparison is meant to prevent. If a project spec requires a fire rating for the finished slat assembly, that needs a separate test on the slat construction itself.

MOQ and Pricing — What’s Still Unresolved

BEIEN’s own pages disagree on minimum order quantity: company history and customized-service pages state 50 panels, while some individual product pages list 100. This applies to both slat lines and hasn’t been standardized, so confirm the current MOQ for the specific model and finish at quoting stage rather than assuming either figure.
Pricing is quotation-based and depends on panel type, dimensions, thickness, surface finish, fire-performance requirements, customization level, packaging, order quantity, and shipping terms — there’s no published price range for either the BN series or PET Slat Panels to cite here.How This Construction Compares to the Broader Market
Compared to common wood-slat wall systems on the market, which typically combine an MDF or solid-wood slat face with a separately sourced PET felt backer, BEIEN’s BN series follows the same general principle — a veneered slat over a felt acoustic layer — but ties the felt component to its own in-house PET production rather than a third-party felt supplier. That doesn’t change the physics of the assembly, but it does mean the backing material’s specification traces back to one factory’s documentation rather than a separate vendor’s data sheet.

FAQ

Does BEIEN’s SGS fire test cover the slat panels in this comparison?

No. The B-s2,d0 classification (SGS SHFS2403000289FF, EN 13501-1:2018) was tested on a 9mm flat PET board sample, model BN-002 — not on a wood slat or PET slat panel assembly.

Are wood slat and PET slat panels the same size?

The 2026 catalog lists both at 2400/2700/3000 × 605mm, 18 or 21mm thick. A separate product page for PET Slat Panels shows 1220 × 2440mm in 6/9/12/24mm thicknesses instead — this conflict is unresolved and should be checked per SKU.

Does the FSC certificate apply to both products?

The FSC Chain of Custody scope covers timber-based products, which is directly relevant to the wood slat (BN) line. It has no bearing on the all-polyester PET Slat Panel, which contains no timber content.

What’s the MOQ?

BEIEN’s site states 50 panels in some places and 100 in others. Confirm the current figure for the specific model before ordering.
If ceiling installation or a project-specific fire rating is part of your spec, that’s the confirmation to request from BEIEN before locking in either product — not something either catalog currently answers on its own.
