Polyester acoustic wall panels

What Is a Polyester Acoustic Panel?

A polyester acoustic panel is a porous interior panel designed to absorb reflected sound rather than block sound transmission through a building element. Its fiber structure allows incident sound energy to enter the material, helping reduce excess reflections and reverberation within a room. The product can therefore support clearer, more comfortable acoustic conditions while also functioning as a decorative surface.

This distinction matters when planning a project. A sound-absorbing panel controls sound within a space; it should not be described as a complete soundproofing system unless a separate wall, door, floor, or ceiling assembly has documented transmission-loss performance.

Material, Colors, and Finishes

The LEEYIN panel uses a polyester fiber core with a matte, textile-like architectural appearance. Buyers can select the base-material color or a spray-painted finish, with multiple colors and customized options available according to the applicable color card.

The material can support restrained single-color installations or combinations of charcoal, neutral, natural, and accent tones. Panels may be arranged as large sheets, narrow vertical elements, geometric modules, layered relief patterns, or other project-specific layouts. Final color, finish, edge appearance, and format should be approved using samples or production references before a bulk order.

Thickness, Density, and Size Options

Standard thicknesses are **9 mm and 12 mm**. The TDS lists density options of **110, 130, 148, and 200 kg/m³**, allowing product selection to be discussed according to the required construction and format.

The standard-size field is written in the TDS as **2400 / 1200 / 600 × 1200 / 600 mm**, with custom sizing also available. Because the document does not map every length-width combination to each model, buyers should confirm the exact sheet format, usable dimensions, tolerances, and packing arrangement during quotation.

Model references include **LYJZ-12, LYJZ-15, LYJZ-25, and LYJZ-50**, together with custom products. These model codes should not be interpreted as thicknesses or densities without a matching model specification.

Acoustic Performance

The supplied TDS reports an **NRC of 1.00 for a 9 mm polyester panel**, tested according to **ASTM C423-23e1**. Reported absorption coefficients include **0.46 at 100 Hz**, **0.80 at 125 Hz**, **0.99 at 400 Hz**, **1.08 at 500 Hz**, and **1.10 at 2.5 kHz**.

These results indicate useful absorption across a broad frequency range in the tested configuration. Actual room performance will depend on coverage area, mounting method, air space, backing materials, room geometry, existing finishes, and the location of the panels. For projects with a defined reverberation-time target, the required surface area and assembly should be reviewed as part of the acoustic design.

Fire and Emissions Information

The TDS states a reaction-to-fire result of **B (B-s1,d0)** under its referenced GB/EN framework, citing **GB 8624-2012** and **EN 13501-1:2018**. It also reports formaldehyde emissions of **≤ 0.025 mg/m³ (ENF)** with reference to **GB/T 39600-2021** and **GB/T 17657-2022**.

Project teams should request the applicable reports and confirm that the tested construction matches the ordered thickness, density, finish, color, and intended installation. The product should not be called “fireproof”; the exact reaction-to-fire classification is the accurate specification language.

Polyester acoustic panels are suitable for interior projects that need to manage reflected sound while maintaining control over color, pattern, and architectural appearance.

– **Offices and meeting rooms:** Help reduce distracting reflections and support clearer workplace communication.
– **Reception and collaborative areas:** Create branded acoustic feature walls using coordinated colors and modular layouts.
– **Schools and multipurpose rooms:** Add absorptive wall or ceiling coverage where speech clarity and reverberation control are project priorities.
– **Studios and media rooms:** Support mid- and high-frequency absorption in voice, recording, rehearsal, and playback environments.
– **Retail and showrooms:** Combine product display, visual zoning, and decorative acoustic treatment.
– **Hotels and restaurants:** Integrate sound-absorbing finishes into guest-facing commercial interiors.
– **Auditoriums and arts spaces:** Supplement a professionally designed acoustic treatment strategy with configurable absorptive surfaces.
– **Ceiling concepts:** Form hanging elements, baffles, clouds, or sculptural features when supported by an approved suspension system.

Final suitability and coverage should be reviewed according to room size, surface finishes, occupancy, acoustic targets, and applicable building requirements.

The technical data sheet illustrates a representative wall assembly in which the polyester fiber acoustic panel is installed with **brad nails and adhesive** over **12 mm perforated plywood**. The illustrated system also includes a lightweight block wall, **C50 light-gauge steel studs**, **50 mm, 52 kg/m³ formaldehyde-free ultrafine glass acoustic insulation**, galvanized steel angles, and M8 expansion bolts.

This section detail demonstrates one enhanced wall construction; it is not a mandatory installation for every panel or project. The final fixing method must suit the substrate, panel format, layout, building conditions, fire requirements, and approved project drawings.

Recommended installation workflow:

1. Confirm that the substrate is clean, dry, level, and structurally suitable.
2. Check panel dimensions, color batches, layout direction, and joint alignment before fixing.
3. Mark a level installation grid and dry-position the first panels.
4. Apply the approved adhesive and mechanical fixing method for the selected substrate.
5. Maintain consistent joints and press each panel evenly into position.
6. Inspect edges, color sequence, alignment, and surface condition before the adhesive cures.
