PET Becoming the finish of the room.
Acoustic material that becomes the finish of the space. 100% post-consumer recycled polyester fibers, dyed at the fiber stage and compression-molded — color runs through the whole panel, and the cut edge is the same color. No surface coating means no peeling, no fading.
Five thicknesses (9 / 12 / 15 / 24 / 30 mm), 132 standard colors, NRC 0.79–0.90 — thicker panels reach further into low frequencies. Tornex is the official Kingkus dealer in Korea, supplying Felt · 2D panels · 3D panels · tiles, with in-house CNC lines fabricating up to 1.5 × 3.4 m for V-cuts, perforations, and custom sizes. From drawing to install, the designer's intent carried straight into the finish.
Four performances, from a single recycled PET.
100% recycled polyester fibers compressed and molded into PET acoustic panels — refined design and superior sound absorption together. The full palette of colors and patterns makes them at home on walls, ceilings, furniture, partitions, even lighting.
Natural mid/high absorption
The porous PET fiber structure across 9 / 12 / 15 / 24 / 30 mm thicknesses absorbs mid- and high-frequency reverberation. Greater thickness reaches further into low frequencies — without sacrificing visual finish.
100% recycled, 100% eco-friendly
Polyester fibers reclaimed entirely from post-consumer PET bottles. Korean Eco-Label and Low-Carbon Product certifications support green building submissions such as LEED and G-SEED.
Flame-retardant certified
Approved for commercial environments under fire-retardant regulations — public venues, civic facilities, and educational spaces.
In-house CNC fabrication
V-cuts, perforations, and non-standard sizes processed on our own CNC lines (up to 3.4 m).
Made of PET — three types of collections.
We reprocess recycled PET bottle pellets and high-temperature compress them with various molds to create diverse collections.
Uncoated, color as the fiber itself.
PET acoustic panels are never surface-coated. Color is set at the fiber stage and runs uniformly through the panel — the consistency of that finish is the mark of an experienced manufacturer.
The Tornex PET design tile palette currently covers 132 colors, with new additions on a rolling basis.

A single PET design tile palette of 135 colorways. RAL and Pantone custom matching is handled through the Custom Catalog.
Quantity and performance, predicted.
We simulate thickness, air gap, and density combinations at drawing level and calculate the minimum quantity needed to meet your target RT60.
Material and service verified by certification
Certified to GRS, OEKO-TEX, Global GreenTag, EPD, HPD, and other leading environmental and quality standards.
Frequently asked questions.
Common questions from teams evaluating PET acoustic panels.
Q1How does absorption change with thickness?+
Per KCL-accredited test reports (KS F 2805), NRC is 0.79 at 9 mm, 0.84 at 12 mm, and 0.90 at 24 mm — low-frequency absorption improves as thickness grows. These figures were measured with a 56 mm air cavity behind the panel (timber frame · type-E mounting). Mounted directly on the wall with no cavity, absorption below 250 Hz drops, so for full low-end control we recommend 24 mm or installation with a rear air cavity.
Q2What fire-retardant certification is held?+
KS F 2844 Class 1 flame-retardant certified. Meets the requirements specified by Korea's Multi-Use Facility Act, school facility codes, and public-agency specifications.
Q3What installation methods are supported?+
For direct wall or ceiling mounting, use staples or hot glue for temporary placement and silicone adhesive for permanent fixing. Louver or cloud applications can use purpose-built or commercially available hardware.
Q4How far does color matching go?+
We carry 132 colors as standard, with stocked colors ready for immediate shipping. Pantone custom matches outside the standard range can also be produced — MOQ and lead time provided on request.
Q5Can V-cuts and perforations be fabricated?+
Share a reference photo or drawing and we'll quote the build. Our CNC lines are dedicated to PET and deeply tuned to the material — and we operate the only PET fabrication machine in Korea capable of handling panels up to 3.5 m. Browse our Custom Hub for past project examples.
