  • Acoustic | Sound-Absorbing PET Panel | Herringbone Pattern | 300x300x9mm | Black

    Code: ES-SW-339

    Acoustic PET fibre panel with a herringbone-pattern surface is intended to reduce room echo, reverberation and some unwanted sound reflections. The panel is made of pressed PET polyester fibre and can be used as a functional and decorative acoustic finish for walls or ceilings.

    The surface features repeating diagonal rectangular segments that meet in a V shape and form a decorative herringbone or chevron pattern. The lines separating the segments divide the continuous surface into a directional geometric composition. Panel dimensions: 300×300 mm, thickness: 9 mm. 

  • Acoustic sound-absorbing PET panel – 300×300×9 mm, herringbone pattern, black

    Acoustic PET fibre panel with a herringbone-pattern surface is intended to reduce room echo, reverberation and some unwanted sound reflections. The panel is made of pressed PET polyester fibre and can be used as a functional and decorative acoustic finish for walls or ceilings.

    The surface features repeating diagonal rectangular segments that meet in a V shape and form a decorative herringbone or chevron pattern. The lines separating the segments divide the continuous surface into a directional geometric composition. Panel dimensions: 300×300 mm, thickness: 9 mm.

    Important information about the intended use:
    The PET acoustic panel is primarily intended to improve room acoustics by reducing echo, reverberation and some sound reflections. By itself, it does not provide complete sound insulation between adjacent rooms and does not replace an airtight, massive, multilayer sound-insulating structure.
    Important information about flammability:
    The supplied information describes the panel as flame-retardant or slower-burning, but no specific reaction-to-fire class, test standard or certificate is stated. Where a project includes fire-safety requirements, the test documentation for the specific product must be used.
    Important composition information:
    The supplied information states that up to 60% of the panel may be made from recycled PET bottles. The actual recycled-material content may vary between production batches.
    Main purpose:
    The panel is installed on walls or ceilings when it is necessary to reduce room echo, soften sound reflections from hard surfaces, improve speech or recording clarity and create a decorative herringbone-pattern acoustic surface.

    Acoustic operating principle

    When sound waves reach the porous PET fibre structure, part of their energy enters the spaces between the intertwined fibres and is attenuated within the material. This helps reduce the intensity of sound reflections returning from walls or ceilings.

    The lines separating the diagonal segments and the V-shaped pattern divide the completely flat surface into geometric zones oriented in different directions. The PET fibre structure absorbs part of the sound energy entering the panel, while the segmented surface creates a decorative relief effect.

    The actual acoustic result depends on the area covered with panels, room size, wall and ceiling materials, furniture, installation location, air gap, panel density and sound frequency.

    Sound absorption and sound insulation are not the same:
    The PET acoustic panel reduces sound reflections within a room but does not block all sound transmission through a wall. Sound insulation requires airtight, massive and properly designed wall, ceiling or floor structures.

    Herringbone-pattern surface

    The panel surface features vertical bands of repeating diagonal segments. Adjacent segments are oriented in opposite directions and meet in a V shape, making the surface resemble a herringbone or chevron pattern.

    • creates a directional decorative geometric pattern;
    • divides the continuous surface into diagonal segments;
    • the V-shaped joints give the surface a rhythmic structure;
    • allows several panels to be combined into a larger wall composition;
    • suitable for modern, minimalist and geometric interiors;
    • can be used for both acoustic and decorative finishing.
    Shape description:
    The surface of this panel may be described as herringbone pattern, chevron style, V-shaped geometric profile or segmented with diagonal rectangles.

    9 mm PET fibre panel

    The panel thickness is 9 mm. This is a thin acoustic and decorative finishing panel that projects only slightly from the wall and is suitable where a compact construction is important.

    The 9 mm PET panel is primarily intended to reduce room echo and some sound reflections. The exact operating frequency range depends on panel density, installation method, air gap and the overall acoustic construction.

    Installing the panel on an additional acoustic backing or leaving an air gap can alter the acoustic properties of the complete construction. The exact effect must be assessed according to the specific installation system.

    Acoustic performance:
    The supplied specification does not state a sound absorption coefficient, NRC, αw, panel density or test standard. Therefore, it is not possible to specify precisely what proportion of sound the panel absorbs in individual frequency ranges.

    PET polyester fibre construction

    The panel is made of pressed PET polyester fibre. It is stiffer and retains its shape better than soft polyurethane foam, making it suitable for decorative modular wall and ceiling finishing.

    • porous fibre structure for absorbing part of the sound energy;
    • rigid, shape-retaining construction;
    • thin 9 mm profile;
    • low weight and easier installation;
    • can be cut and adapted to the installation location;
    • up to 60% of the composition may consist of recycled PET material;
    • the black colour suits modern, minimalist and technical interiors.
    Recycled PET material:
    The supplied information states that up to 60% of the panel may be made from recycled PET bottles. In this way, part of the used plastic can be returned to the production cycle and used in a new product.

    Calculating the required quantity

    The area of one 300×300 mm PET panel is 0.09 m². To cover a theoretical area of 1 m², approximately 11.1 panels would be required, so in practice it is recommended to calculate 12 panels per square metre, excluding cutting and installation losses.

    Number of panels Approximate coverage area
    1 pc. 0.09 m²
    6 pcs. 0.54 m²
    12 pcs. 1.08 m²
    24 pcs. 2.16 m²
    48 pcs. 4.32 m²

    9 mm PET acoustic panel with a herringbone pattern for reducing room echo and sound reflections

    The acoustic PET fibre panel is intended to absorb part of the sound travelling through a room and reduce reflections from walls and ceilings. The diagonally arranged segments meet in a V shape to create a decorative herringbone or chevron pattern.

    The 300×300×9 mm modules can be installed on walls or ceilings, combined into larger geometric compositions and cut to suit the shape of the room when required.

    The pressed PET fibre construction is thin, rigid and suitable for decorative acoustic finishing. The supplied information states that up to 60% of the panel composition may consist of recycled PET material.

    The PET acoustic panel improves room acoustics but is not a complete sound-insulation system. For a precise acoustic or fire-safety project, sound absorption, reaction-to-fire and material-emission test documentation must be checked.
