Decorative acoustic MDF slat panel – 2400×600×22 mm, PET felt, NRC 0.8, dark walnut

Decorative acoustic wall and ceiling panel consisting of wood-effect MDF slats and sound-absorbing PET fibre felt. It is designed for interior finishing, improving room acoustics and reducing the effect of unwanted echo and sound reflections.

Dark walnut engineered wood veneer features a darker, muted brown tone with a clearly visible longitudinal wood grain. The black acoustic backing highlights the slats and helps create a solid, modern and rhythmic wall or ceiling surface.

The declared sound absorption coefficient is NRC 0.8. The actual sound absorption performance depends on the panel installation method, the complete construction and the room conditions.

• helps reduce echo in the room;
• reduces unwanted sound reflections;
• may improve speech intelligibility;
• helps reduce the perception of reverberation;
• suitable for residential, working, social and leisure spaces.

The MDF slat surface is covered with dark walnut engineered wood veneer. The finish features a darker, muted grey-brown tone and a distinctive longitudinal wood grain.

• darker and more subdued walnut tone;
• distinctive longitudinal wood grain;
• solid and modern surface appearance;
• combines well with black, grey, beige and white surfaces;
• can be combined with concrete, glass, metal and stone finishes;
• suitable for modern, industrial and minimalist interiors.

The slats are made using MDF board with a declared emission class of CARB P2.

• MDF board with controlled formaldehyde emissions;
• suitable for interior finishing products;
• uniform structure helps maintain the shape of the slats;
• surface suitable for decorative finishing;
• designed for use under normal indoor conditions.

The black rear backing is made from compressed PET fibres. The PET felt forms the acoustic backing to which the MDF slats are attached.

• absorbs part of the sound reaching the panel;
• helps reduce room reverberation;
• creates a contrasting background between the dark walnut slats;
• forms the backing for the MDF slats;
• helps reduce the impact of sound reflected from hard surfaces.

The provided technical data indicates that the acoustic PET felt, depending on the specific version and testing system, may have different fire classifications:

• EN 13501-1:2018 classification;
• ASTM E84 Class A classification;
• a B1 flame-retardant PET felt version is also mentioned.

• Sound absorption – helps reduce echo and reverberation in the room.
• NRC 0.8 – declared sound absorption rating.
• MDF slat construction – provides a rhythmic and modern surface design.
• PET acoustic felt – provides a sound-absorbing backing.
• Dark walnut finish – creates a rich, subdued wood-effect appearance.
• CARB P2 MDF – controlled formaldehyde emissions.
• Screw or suitable adhesive installation – depending on the substrate construction.
• Suitable for walls and ceilings – for various interior design solutions.
• 2400 mm length – convenient for continuous wall finishing.
• One panel covers 1.44 m².

• Living rooms – for TV walls or accent interior areas.
• Bedrooms – for the wall behind the bed and a cosier environment.
• Home offices – to reduce echo and sound reflections.
• Office rooms – for solid decorative and acoustic finishing.
• Meeting rooms – to improve speech intelligibility.
• Hotels – for rooms, corridors and common areas.
• Restaurants and cafés – to improve acoustic comfort.
• Reception areas – as a representative and darker wall background.
• Studios – for partial control of sound reflections.
• Educational spaces – to reduce reverberation.
• Retail spaces – as a solid and modern interior accent.
• Ceiling finishing – where a decorative and sound-absorbing surface is required.

For example, a dark walnut slatted acoustic wall can be installed behind a television in a living room. The 2400 mm long panels are installed vertically, with the edges joined so that the slat pattern remains continuous.

The black PET felt is visible between the dark brown MDF slats, creating a subdued contrast. At the same time, the acoustic backing helps absorb part of the sound travelling through the room and reflected from hard surfaces.

The perception of echo in the room may be reduced, while the wall becomes a distinctive, darker and solid interior accent.

If greater sound absorption is required, the panels can be installed on a frame with an air gap and, if necessary, an additional layer of acoustic mineral wool.

For home users: suitable for living rooms, bedrooms, TV walls, home offices or other spaces where dark wood-effect finishing is to be combined with improved room acoustics.

For interior designers: allows the creation of vertical or horizontal slat compositions, accent walls and ceiling zones by combining the dark walnut surface with the black PET acoustic backing.

For offices and commercial spaces: can be used in meeting rooms, offices, reception areas, hotels, restaurants, cafés and other spaces where both representative interior appearance and reduced echo and reverberation are important.

For acoustic improvement: suitable for rooms containing many hard sound-reflecting surfaces. The panels help absorb part of the sound energy and reduce unwanted sound reflections within the room.

For installers: the panels can be installed vertically or horizontally, cut to the required dimensions and adapted around electrical sockets, switches or other interior elements. For walls, mechanical fastening or suitable mounting adhesive can be used, while reliable mechanical fastening is recommended for ceilings.

1. Measure the wall or ceiling. Calculate the required number of panels and allow extra material for cutting.
2. Check the substrate. It must be dry, solid, level and free from loose finishing layers.
3. Plan the slat direction. Decide whether the panels will be installed vertically or horizontally.
4. Mark the position of the first panel. Use a spirit level or laser level.
5. Cut the panel if necessary. MDF slats should be cut using a suitable woodworking tool, while PET felt can be cut with a sharp knife.
6. For adhesive installation, apply the mounting adhesive according to the adhesive manufacturer's instructions.
7. For screw installation, fasten the panel through the PET backing. Fastening points can be positioned between the slats.
8. Check the slat direction and spacing. Adjacent panels should continue the overall pattern consistently.
9. Cut openings for sockets and switches only after their positions have been accurately marked.
10. Finish visible edges. If necessary, use suitable finishing profiles or other edge-finishing solutions.
11. After installation, remove dust using a soft brush or vacuum cleaner.

• Remove dust using a vacuum cleaner with a soft brush attachment.
• Clean the surface with a dry, soft cloth.
• Clean the gaps between the slats with a soft brush.
• Do not use large amounts of water.
• Do not use abrasive sponges.
• Do not use aggressive chemical cleaners.
• Do not allow moisture to reach the cut edges of the MDF slats.

• The panel is intended for dry indoor spaces.
• Do not use in areas exposed to direct water.
• MDF is not designed for continuous exposure to high humidity.
• Allow the panels to acclimatise to the room conditions before installation.
• Check the actual panel and slat dimensions before cutting.
• Use fasteners suitable for the substrate and panel weight.
• Mechanical fastening is recommended for ceilings.
• The suitability of adhesive-only installation on ceilings must be verified according to the technical specifications of the adhesive used.
• Disconnect the power supply before installation around electrical equipment.
• The panel is not a structural or load-bearing element.
• The NRC 0.8 result depends on the complete installation system and covered area.
• The fire classification must be checked according to the certification documents for the specific product.
