PET, Fabric-Wrapped or Wood Slat Acoustic Panels: Which Should You Specify?

Compare PET felt, fabric-wrapped and wood slat panels against the acoustic target, appearance, fire requirements and maintenance conditions of each space. Absorption depends on the complete build-up and mounting arrangement; fire evidence must also cover the specified product and assembly. FBM Sourcing coordinates the selected products as a sourcing partner.

FBM Sourcing supplies all three panel families from Chinese production for hotel, office, school and apartment projects as a building material sourcing agent, so this comparison is written the way a specifier actually decides: by room, by rating, and by what survives contact with the public. The product-page counterparts — acoustic wall panels from China and acoustic ceilings from China — cover the buying process; this page settles which type belongs on your drawings.

Quick Summary: Which Acoustic Panel Type for Which Space?

How Do the Three Panel Types Compare on Acoustic Performance?

Obtain the acoustic report for the nominated product, thickness, backing, air gap and mounting arrangement. Direct-fixed panels, suspended baffles and panels on cavities are different test configurations. Compare results that correspond to the proposed installation instead of assigning NRC ranges to PET, fabric-wrapped or wood slat families.

Keep the installation build-up shown in the report with the procurement specification. If the cavity, backing or fixing method changes, ask the supplier and acoustic designer whether the reported result still applies. A brochure value without its mounting condition is insufficient for that comparison.

Have the acoustic designer set the required treatment and coverage for the room, taking account of the other surfaces and intended use. Select panels against that design and their matching reports rather than a universal NRC target by room name.

Fire Ratings: What Do ASTM E84 Class A and B-s1,d0 Require Here?

Specify the required fire classification for the actual project and request the report for the complete panel build-up, including core, facing, adhesive and backing where relevant. Do not treat ASTM E84 and EN 13501-1 classes as equivalents. A report for one thickness or construction does not automatically cover a different panel profile.

For school, hospital and government projects this paperwork is not a formality — it is the submittal that decides whether the container clears the consultant’s desk. Batch-matched test reports are requested with the order, and verification that the shipped goods match the certified specification happens at the factory, by FBM Sourcing’s own QC team, documented in photos and video before loading.

How Do the Three Types Compare on Cost Logic?

Without quoting numbers that shift with fiber, fabric and timber markets, the supplied-cost ranking is stable: PET is the budget floor, fabric-wrapped sits mid-range with the fabric choice driving the spread, and wood slat tops the table — a real-veneer slat panel can run to a multiple of the PET cost for the same wall area. Two structural points refine that ranking on a project budget. First, installed cost compresses the gap: PET’s knife-cut, glue-up installation is the fastest of the three, while fabric-wrapped panels ordered to size leave no site trimming at all, so labor-expensive destinations favor both against slat systems that need battens and cavity work. Second, panels are a materials-dominated trade — the product itself carries most of the installed cost, which is exactly the profile where ex-factory Chinese pricing moves a budget most, the same logic that governs which partition packages are worth importing.

Compare the confirmed panel weights, packed dimensions and handling instructions in the shipping plan. Different constructions can change pallet weight, lifting requirements and container space. Calculate those quantities from the actual packing list rather than a material-family weight range.

What Are the Lead Times, and What Should the Order Include?

Production windows are short relative to furniture: ex-factory lead times for PET panels, fabric-wrapped panels and wood slat systems are confirmed by the factory in writing for each order, with sea freight on top, confirmed by the carrier at booking. The order file matters as much as the dates. It should fix the acoustic targets per room (so substitutions can be checked against something), name the fire classification and the exact thickness the certificate covers, include an approved control sample per finish, and carry a cutting overage on any patterned or mitered layout. Color consistency is the quiet risk on PET — fiber batches vary, so panels for one continuous wall should be produced in one run rather than topped up later.

Durability, Weight and Installation: The Site Realities

At a glance, the physical comparison:

At sample review, inspect edge protection, cleanability, repair options and the proposed fixing method. For panels within reach, agree the required impact and maintenance performance. Confirm the actual panel weight and suitable support with the installer before ordering.

Which Rooms Get Which Panel on a Real Project?

On a full commercial fit-out the answer is almost never one panel type — it is a schedule. A typical hotel splits three ways: wood slat across the lobby, reception and restaurant feature walls; fabric-wrapped in the ballroom and boardrooms where the acoustic consultant’s reverberation targets bite; PET in back-of-house corridors, the gym and staff areas. An office project inverts the ratio — PET across the open plan and ceiling baffles, fabric-wrapped in the townhall room, wood slat at reception only. A school is PET nearly wall-to-wall, with fabric-wrapped reserved for the auditorium, and its assembly-space walls should be read alongside the partition strategy in our guide to glass, drywall and movable partitions for commercial fit-outs.

Two coordination notes complete the schedule. First, walls are only half the acoustic package — the ceiling plane usually carries more treatable area, and the parallel decision is covered in mineral fiber vs gypsum vs metal ceilings. Second, freight favors consolidation: all three panel types flat-pack efficiently, and a 40-foot high-cube carries a large area of PET panels — which is why acoustic packages ride along with the wider fit-out container plan rather than shipping alone.

Once the panel type is settled the next question is who makes it — see acoustic panel manufacturers in China for commercial interiors for the supplier types, the production clusters and the test evidence worth requesting from each.

Get a China Procurement Quote for Your Project

If you are specifying acoustic panels for a hotel, office, school or apartment project, send the room schedule and target ratings — a china sourcing agent working at the production end will price PET, fabric-wrapped and wood slat options against the same drawings, with per-thickness fire reports, control samples for approval, and inspection by our own QC team before anything ships. Submit your BOQ or drawings, quantities, destination port and timeline through our China procurement inquiry page, and our team will review your requirements and get back to you.
