Decorative acoustic wall panel with hourglass-shaped elements – 482.87×861.94×18 mm, MDF + PET, grey-brown walnut imitation

Decorative acoustic wall panel consists of repeating hourglass-shaped MDF elements covered with engineered wood veneer and a black sound-absorbing PET fibre backing. The elements are arranged in an overlapping, irregular geometric composition, creating an expressive relief pattern while providing both decorative and acoustic functions.

Grey-brown walnut-effect surface features muted brown, walnut, grey-brown, darker chocolate and earthy tones. The longitudinal and locally pronounced wavy wood-grain pattern gives the surface a character close to natural walnut, while the black PET backing between the elements emphasises their angular shapes and creates a strong contrast.

• the elements have wider ends and a narrowed central section;
• different element orientations create an irregular geometric pattern;
• the overlapping effect adds visual depth to the wall;
• the black PET backing emphasises the outlines of the elements;
• the angular edges help scatter some sound reflections;
• several panels can be joined to create a larger wall composition.

The visible surface of the MDF elements is covered with engineered wood veneer. Its colour, texture and pattern are designed to resemble grey-brown-toned walnut wood.

• decorative natural-wood surface effect;
• more uniform and controlled wood pattern;
• muted brown, walnut and grey-brown tones;
• darker chocolate and earthy shades visible in places;
• visible longitudinal and locally pronounced wavy wood grain;
• the grain direction of individual elements may differ visually;
• suitable for wall finishing in residential and commercial interiors;
• the surface is not natural walnut veneer or solid walnut.

The surface has a muted grey-brown walnut shade. Medium-dark brown, grey-brown, walnut, darker chocolate and earthy tones predominate, complemented by a clearly visible wood-grain texture.

• medium-dark grey-brown wood shade;
• brown, walnut and muted earthy tones;
• darker chocolate shades visible in places;
• longitudinal and locally pronounced wavy wood lines;
• slight differences in tone may occur between individual elements;
• strong contrast with the black PET backing;
• coordinates with black, cream, grey and beige surfaces;
• can be combined with concrete, glass, metal and stone finishes;
• suitable for modern, industrial, classic and minimalist interiors.

The panel backing is made from compressed black PET fibre felt. It performs acoustic, structural and decorative functions: it absorbs part of the sound energy, supports the MDF elements and forms a black background between them.

• helps absorb part of the sound reaching the panel;
• reduces some sound reflections from hard walls;
• may help reduce the perception of reverberation;
• creates a black background between the MDF elements;
• emphasises the outlines of the hourglass-shaped elements;
• creates black geometric lines of varying widths;
• contrasts with the grey-brown walnut-effect surface;
• joins the individual MDF elements into a single module.

• Decorative wall finish – for an expressive and relief interior surface.
• Acoustic function – to absorb part of the sound energy and reduce reflections.
• Hourglass-shaped elements – for an irregular geometric wall composition.
• Overlapping pattern – for a dynamic surface with visual depth.
• Engineered wood veneer – for a more uniform decorative pattern.
• Grey-brown walnut imitation – for a muted, neutral and solid wood surface.
• Black PET felt – for acoustic performance and a contrasting background.
• Angular element edges – papildomai garso sklaidai ir reljefiniam efektui.

• – for a representative and modern finish. – for a feature wall and to reduce some sound reflections.
• Hotels – for rooms, corridors and common areas.
• Restaurants and cafés – for decorative acoustic finishing.
• Reception areas – for a distinctive and presentable backdrop.
• Retail spaces – as a backdrop for displays and products.
• Lounge and waiting areas – for a cosier and visually expressive environment.

For example, a decorative acoustic wall with a grey-brown walnut effect is created behind the television in a living room. The panels are positioned next to one another after first checking the direction of the hourglass-shaped element pattern.

Muted brown, walnut and grey-brown tones create a more neutral and restrained wood backdrop. The black PET backing emphasises the angular elements and adds visual depth to the wall.

The PET backing absorbs part of the sound reflected from the television, speakers, floor, ceiling and other hard surfaces. This may reduce the perception of echo and reverberation within the room.

Where required, openings can be planned in the panels for electrical sockets, switches, a television bracket or lighting cables; however, their positions must be marked accurately before cutting.

1. Measure the wall. Calculate the required number of panels and allow a cutting margin.
2. Check the substrate. The wall must be dry, solid, level and free from loose or peeling finish layers.
3. Plan the composition. Determine in advance how the hourglass-shaped element pattern will continue.
4. Lay the panels out on the floor. Check the shades, wood-grain direction and alignment between modules.
5. Mark the position of the first panel. Use a spirit level or laser level.
6. Cut the panel if necessary. Cut the MDF elements with a suitable woodworking tool and the PET felt with a sharp knife.
7. For adhesive installation, apply mounting adhesive to the rear of the panel in accordance with the adhesive manufacturer’s instructions.
8. For screw installation, fasten the panel through the PET backing. The screw heads can be concealed in the black felt.
9. Check the module position. The next panel must continue the planned geometric composition.
10. Cut openings for sockets and switches only after accurately marking their positions and disconnecting the electrical supply.
11. Finish the visible edges. Suitable finishing profiles or edge trims can be used for cut edges.
12. Remove dust after installation with a soft brush or vacuum cleaner.

• Remove dust with a vacuum cleaner using a soft upholstery or brush attachment.
• Clean the decorative surface with a dry, soft cloth.
• Clean the gaps with a soft brush or a narrow vacuum-cleaner nozzle.
• Do not use excessive water.
• Do not spray cleaning products directly onto the surface.
• Do not use abrasive sponges or cleaning products.
• Do not use aggressive chemical cleaners or solvents.
• Do not allow moisture to enter the cut edges of the MDF.

• The panel is intended for dry indoor spaces.
• Do not use in areas exposed to direct contact with water.
• MDF is not intended for continuously high humidity.
• Grey-brown walnut imitation is not natural walnut veneer or solid walnut.
• The colour shown on screen may differ from the actual product shade.
• The pattern and distribution of tones may vary between elements and production batches.
• Before installation, allow the panels to acclimatise to the room temperature.
• Check the actual panel dimensions before cutting.
• Use screws and wall plugs suitable for the substrate and the weight of the panel.
• Before installing several modules, the pattern direction and alignment must be checked.
• Disconnect the electrical supply before cutting around electrical equipment.
• The panel is not a structural or load-bearing element.
• The acoustic result depends on the covered area and installation system.
• Check the fire-reaction and sound-absorption ratings in the documentation for the specific product.

Quick selection guide

Choose a grey-brown walnut-effect acoustic panel with geometric elements when an expressive, relief wall finish in restrained wood tones is required that also helps reduce some room echo and unwanted sound reflections.

Hourglass-shaped elements, grey-brown walnut imitation and black acoustic backing

The decorative acoustic panel combines hourglass-shaped MDF elements, engineered wood veneer and a black sound-absorbing PET fibre backing. Elements arranged in different directions create a dynamic, overlapping and visually expressive geometric composition.

The grey-brown walnut-effect surface combines muted brown, walnut, grey-brown, chocolate and darker earthy tones. The black PET backing highlights the angular outlines of the elements and gives the wall a solid, contrasting and modern character.

The panel is intended for accent wall finishing and to improve the room’s acoustic comfort. It can help reduce some unwanted sound reflections and reverberation, but does not replace a complete sound-insulation structure.

The 482.87×861.94×18 mm modules can be installed with screws or suitable mounting adhesive and joined into larger wall compositions. Precise alignment creates a continuous, rhythmic and unconventional geometric surface.
