Decorative Acoustic MDF Slat Panel – 600×600×22 mm, PET Felt, NRC 0.8, Walnut Finish

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 impact of unwanted echo and sound reflections.

The walnut-finish engineered wood veneer gives the panel a warm, rich natural wood appearance, while the black acoustic backing highlights the slats and helps create a modern, rhythmic wall or ceiling surface.

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

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

The MDF slat surface is covered with walnut-effect engineered wood veneer. It reproduces the texture of natural wood and gives the surface a rich brown tone.

• warm and rich walnut tone;
• suitable for modern, classic and premium interiors;
• matches black, beige, grey and white surfaces;
• can be combined with metal, concrete, glass and natural stone;
• creates a natural wood appearance without a solid wood construction.

The slats are made from MDF board with a stated 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;
• intended for use under normal indoor conditions.

The black rear backing is made from compressed PET fibres. 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 black background between the walnut slats;
• forms the base for the MDF slats;
• helps reduce the impact of sound reflected from hard surfaces.

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

• EN 13501-1:2018 classification;
• ASTM E84 Class A classification;
• an additional 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.
• Walnut finish – creates a warm and rich wood-effect appearance.
• CARB P2 MDF – controlled formaldehyde emissions.
• PET fibre sound-absorbing felt – supports the acoustic properties of the panel.
• Screw or adhesive installation – depending on the substrate construction.
• Suitable for walls and ceilings – for various interior design solutions.
• Square 600×600 mm format – suitable for creating modular compositions.
• One panel covers 0.36 m².

• Living rooms – for TV walls or accent interior zones.
• Bedrooms – for walls behind beds or decorative accent areas.
• Home offices – to reduce echo and sound reflections.
• Office rooms – for decorative and acoustic wall 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 wall background.
• Studios – for partial control of sound reflections.
• Training and educational spaces – to reduce reverberation.
• Retail spaces – as a warm and sophisticated interior accent.
• Ceiling finishing – when a decorative and sound-absorbing surface is required.

For example, a decorative walnut-coloured slat area can be created behind a television in a living room. The 600×600 mm panels can be arranged in several rows while maintaining a continuous slat rhythm.

The black PET felt is visible between the rich walnut-coloured MDF slats, creating a contrasting background. At the same time, the acoustic backing helps absorb part of the sound travelling through the room and reflected from hard surfaces.

The square format allows the entire wall to be covered or selected accent areas to be created, such as a background for a television, desk, bed or relaxation area.

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 rich wood-effect finishing is desired together with improved room acoustics.

For interior designers: the 600×600 mm modular format allows accent areas of various sizes, vertical or horizontal slat compositions, and combinations of the walnut surface with the black PET acoustic backing.

For offices and commercial spaces: suitable for meeting rooms, offices, reception areas, hotels, restaurants, cafés and other spaces where both a 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 square 600×600 mm format is convenient for smaller areas and around other interior elements. The panels can be oriented vertically or horizontally, cut to the required dimensions and adapted around electrical sockets, switches or other elements. Reliable mechanical fixing is recommended for ceilings.

1. Measure the wall or ceiling. Calculate the required number of panels and allow additional 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 how the slats of individual 600×600 mm panels will be oriented.
4. Mark the position of the first panel. Use a spirit level or laser level.
5. Cut the panel if required. MDF slats should be cut with a tool suitable for woodworking, while PET felt can be cut with a sharp knife.
6. For adhesive installation, apply mounting adhesive according to the adhesive manufacturer's instructions.
7. For screw installation, screw the panel through the PET backing. Fixing points can be positioned between the slats.
8. Check the panel position and slat rhythm. Adjacent panels should form the desired continuous composition.
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.

• Vacuum dust using 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 enter the cut edges of the MDF slats.

• The panel is intended for dry indoor spaces.
• Do not use it in areas exposed to direct water.
• MDF is not intended 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 screws and plugs suitable for the substrate and panel weight.
• Reliable mechanical fixing is recommended for ceilings.
• Disconnect the power supply before working 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.
• Check the fire classification according to the certification documents for the specific product.
• Project installation should be carried out by a qualified finishing or construction professional.
