What the panel is made of, and what it does

Three layers, one product family. Below: the construction, the measured absorption figures and the honest limits of both.

Panel construction: MDF slats, polyester fibre felt, MDF backing
Construction

The three layers

Wearing faceMDF slats, 6 mm, 750 g/m² density, cut on a CNC. Carries the pattern and the rigidity.
Absorbing corePolyester fibre felt in 500 / 800 / 900 / 1000 / 1350 g/m², 3–7 mm depending on the build. Open-cell, this is the layer that absorbs sound.
BackingThe felt itself acts as the backing. Shaped panels add a black MDF rear layer to hold the relief.
FinishTechnical wood veneer or PVC film, hot-pressed, 0.2–0.5 mm depending on the series.
Acoustic data

NRC by build

Noise Reduction Coefficient is a single-number average of absorption at 250, 500, 1000 and 2000 Hz. It is useful for comparing products and useless for predicting a room. Figures below are the average of our own sample tests, quoted as a range because the mounting method moves the result.

BuildFeltNRC (sample average)Typical use
DT-1 · 9 mm3 mm / 500 g/m²0.75 – 0.80Corridors, light renovation
DT-2 · 11 mm5 mm / 800 g/m²0.75 – 0.80Offices, classrooms, retail

Mounted on battens?

Add roughly 0.05 to the NRC and a clear improvement below 250 Hz. The most cost-effective upgrade in the range.

Large room?

NRC is not enough. Ask your acoustic consultant for a reverberation-time calculation; we can supply panel dimensions and absorption data for the model.

Certificate needed?

B1 and E0 certificates are supplied with shipping documents on request — needed for most tender files.

NRC absorption comparison chart
Fire and emission

B1 and E0 on every model

Fire rating B1 (China GB 8624) and formaldehyde emission E0 (GB 18580) apply to the complete panel build, not to the veneer on its own. For a tender file, ask for the certificate set — it goes out with the shipping documents at no extra cost.

  • B1: difficult to ignite, self-extinguishing, low smoke
  • E0: formaldehyde emission ≤ 0.05 mg/m³, suitable for interiors with prolonged occupancy
  • Certificates issued per production batch; tell us if your client needs a specific batch reference

Local building codes vary. B1 and E0 satisfy the Chinese national standard — check whether your market requires an additional local test and tell us before the order, not after.

Screen colour is not panel colour. Every series is available as a physical A4 sample — free, you pay the courier. Order the sample before you specify a colour on a 500 m² project.
