Which thickness for your project
The slat face is identical across all five. What changes is how much polyester fibre sits behind it — and that is what determines how much sound the panel absorbs.
Straight Slat Acoustic Panel 9 mm (DT-1)
The slimmest panel in the range. 9 mm total thickness keeps the finished wall under 15 mm, for renovation projects where floor area and door clearance cannot be lost.
| Panel size | 600 × 2400 × 9 mm |
|---|---|
| Total thickness | 9 mm |
| Polyester fibre felt | 3 mm polyester fibre, 500 g/m² |
| MDF backing | 6 mm MDF, 750 g/m² |
| NRC (sample average) | 0.75–0.80 |
| Fire rating | B1 |
| Formaldehyde emission | E0 |
Straight Slat Acoustic Panel 11 mm (DT-2)
Our best-selling thickness. 11 mm balances absorption, rigidity and freight cost, and is the panel most West African distributors stock as a standard line.
| Panel size | 600 × 2400 × 11 mm |
|---|---|
| Total thickness | 11 mm |
| Polyester fibre felt | 5 mm polyester fibre, 800 g/m² |
| MDF backing | 6 mm MDF, 750 g/m² |
| NRC (sample average) | 0.75–0.80 |
| Fire rating | B1 |
| Formaldehyde emission | E0 |
Straight Slat Acoustic Panel 16 mm (DT-3)
16 mm with a 7 mm felt core. The extra fibre mass lifts absorption in the 500–2000 Hz speech band, which is where intelligibility problems start.
| Panel size | 600 × 2400 × 16 mm |
|---|---|
| Total thickness | 16 mm |
| Polyester fibre felt | 7 mm polyester fibre, 1000 g/m² |
| MDF backing | 6 mm MDF, 750 g/m² |
| NRC (sample average) | 0.80–0.85 |
| Fire rating | B1 |
| Formaldehyde emission | E0 |
Straight Slat Acoustic Panel 18 mm (DT-4)
18 mm high-density build for large wall areas. The heavier felt core resists panel drumming on wide stud spacing.
| Panel size | 600 × 2400 × 18 mm |
|---|---|
| Total thickness | 18 mm |
| Polyester fibre felt | Polyester fibre, 1350 g/m² |
| MDF backing | 6 mm MDF, 750 g/m² |
| NRC (sample average) | 0.80–0.85 |
| Fire rating | B1 |
| Formaldehyde emission | E0 |
Straight Slat Acoustic Panel 21 mm (DT-5)
The full 21 mm build — the same construction as our shaped panels, so straight and 3D panels can be mixed on one wall without a visible step.
| Panel size | 600 × 2400 × 21 mm |
|---|---|
| Total thickness | 21 mm |
| Polyester fibre felt | Polyester fibre, 1350 g/m² |
| MDF backing | 6 mm MDF, 750 g/m² |
| NRC (sample average) | 0.80–0.85 |
| Fire rating | B1 |
| Formaldehyde emission | E0 |
Hidden clip joint, no visible fixings
Panels butt-joint edge to edge. The slat pattern is continuous across the joint, and the fixing sits in the gap between slats, so the finished wall shows no screws and no shadow gaps.
- Install on a flat substrate: gypsum board, plywood, MDF or a levelled masonry wall
- Minimum substrate flatness 2 mm over 2 m — check with a straight edge before starting
- Two workers fix 40–60 m² per day on a prepared wall
- Cut with a fine-tooth circular saw; cut edges are covered by the matching edge trim
Where the straight panel is the right choice
Office and meeting rooms
11 mm on corridor walls, 16 mm and above on the wall behind the speaker. The aim is speech clarity, not silence.
Hotel guest corridors
9–11 mm keeps the wall thin and the fire rating intact. The slat pattern hides scuff marks better than a flat painted wall.
Schools and classrooms
16–18 mm on rear and side walls. Some reverberation is needed in a teaching room — do not cover all four walls.
Retail and showrooms
A decorative wall that also fixes the loud-room problem caused by hard floors and glass frontage.
