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

Decorative acoustic wall and ceiling panel consisting of wood-grain 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 dark walnut technical 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 sophisticated, 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;
• can improve speech intelligibility;
• helps reduce the perception of reverberation;
• suitable for residential, working, social and leisure spaces.

The MDF slat surface is covered with a technical wood veneer featuring a dark walnut wood grain. The finish is characterised by a darker, muted grey-brown tone and an expressive longitudinal wood grain.

• darker and more restrained walnut tone;
• pronounced longitudinal wood grain;
• sophisticated and modern surface appearance;
• matches black, grey, beige and white surfaces;
• can be combined with concrete, glass, metal and stone finishes;
• suitable for contemporary, industrial and minimalist interiors.

The slats are made from MDF board with the declared emission class 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 fibre. 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 effect 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 – creates a rhythmic and modern surface design.
• PET acoustic felt – provides a sound-absorbing backing.
• Dark walnut finish – provides a rich, restrained and sophisticated wood-grain appearance.
• CARB P2 MDF – controlled formaldehyde emissions.
• Installation with screws or suitable adhesive – depending on the substrate construction.
• Suitable for walls and ceilings – for various interior design applications.
• 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 zones.
• Home offices – to reduce echo and sound reflections.
• Work offices – for sophisticated 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 – for a representative and darker wall background.
• Studios – for partial control of sound reflections.
• Training rooms – to reduce reverberation.
• Retail spaces – as a sophisticated and modern interior accent.
• Ceiling finishing – when a decorative and sound-absorbing surface is required.

For example, a decorative dark walnut slat zone can be created behind a TV in a living room. The 600×600 mm panels are arranged in several rows while maintaining a consistent slat rhythm.

The black PET felt is visible between the dark brown MDF slats and creates a restrained contrast. 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 only selected accent zones to be created, such as backgrounds for a TV, 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 acoustic mineral wool layer.

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

For interior designers: the 600×600 mm modular format allows accent zones of various sizes, vertical or horizontal slat compositions, and combinations of 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 a representative interior appearance and reduced echo and reverberation are important.

For acoustic improvement: suitable for rooms with 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 composing smaller areas and working 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 fastening is recommended for ceilings.

1. Measure the wall or ceiling. Calculate the required number of panels and allow for cutting waste.
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 each 600×600 mm panel will be oriented.
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 panel position and slat rhythm. Adjacent panels should create the desired continuous composition.
9. Cut openings for sockets and switches only after their exact positions have been marked.
10. Finish visible edges. If necessary, use suitable finishing profiles or other edge-finishing solutions.
11. Remove dust after installation 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 excessive amounts of water.
• Do not use abrasive sponges.
• Do not use aggressive chemical cleaners.
• Prevent moisture from entering the cut edges of the MDF slats.

• The panel is intended for dry indoor areas.
• Do not use in locations 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 fasteners suitable for the substrate and panel weight.
• Mechanical fastening is recommended for ceilings.
• The suitability of adhesive-only ceiling installation must be verified according to the technical specifications of the adhesive used.
• 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 of the specific product.
