vitAcoustic 3D-Wave PET Felt Acoustic Panels – Thermally Formed Wave Design (W18 Profile) for Walls and Ceilings
The vitAcoustic 3D-Wave transforms our proven 9-mm PET felt acoustic panel into a sculptural design element. In a heated press, the flat panel is pressed into an aluminum mold and formed into a three-dimensional wave structure – a sculptural focal point for walls and ceilings that plays with light and shadow while scattering and absorbing sound.
The 3D-Wave is primarily a design product: its wave shape creates depth, movement, and changing patterns of light and shadow throughout the day. Acoustically, it acts as a porous sound absorber with additional sound scattering (diffusion) – it achieves its highest absorption value with an air gap behind the panel. If maximum sound absorption is your priority, we recommend our flat acoustic panels in 9, 12, or 24 mm.
This model uses the W18 mold – a subtle, fine wave pattern for elegant, understated surfaces. An overview of all three wave profiles is provided below.
What Defines the 3D-Wave
Light, shadow, and depth: The sculptural wave breaks up incoming light, creating shifting shadow patterns throughout the day. A flat wall becomes a statement surface with visual depth – ideal wherever a surface is intended to become a design focal point.
Diffusion as an additional benefit: The wave geometry scatters incoming sound in multiple directions rather than reflecting it in a specific direction like a smooth wall. This distributes reflections more evenly throughout the room and reduces flutter echoes between parallel walls – allowing the 3D-Wave to act as a combined absorber and diffuser.
Biophilic appearance: Wave- and hill-like shapes have an organic, calming effect. Combined with LED lighting positioned along the side or behind the panels, they create particularly atmospheric lighting effects in the evening.
W18 Wave Profile and the Three Variants
This model uses the W18 mold: size 2400 × 1200 mm, wave height 7.5 mm, wave spacing 36 mm + 1.5 mm valley – a subtle, fine wave pattern for elegant, understated surfaces.
The 3D-Wave is available in three wave profiles, each offered as a separate model with the full color selection:
-
W17 – 2400 × 1100 mm | Wave height 14 mm | Spacing 33 mm + 14 mm valley – a distinctive, expressive wave with pronounced light-and-shadow effects
-
W18 – 2400 × 1200 mm | Wave height 7.5 mm | Spacing 36 mm + 1.5 mm valley – a subtle, fine wave pattern for elegant, understated surfaces
-
W19 – 2400 × 1200 mm | Wave height 8.5 mm | Spacing 68 mm + 3 mm valley – a broad, expansive wave with a calm, flowing rhythm
Acoustic Performance (Tested to ISO 354, Rated to DIN EN ISO 11654)
The 3D-Wave is a porous sound absorber. Because the 9-mm nonwoven is compressed during pressing, its absorption is slightly lower than that of a flat panel of the same thickness – the air gap behind the panel is critical to achieving a good value. We report the NRC and weighted sound absorption coefficient αw from our own measurements:
-
Directly on the wall (0 mm): NRC 0.25 / αw 0.20 – Class E (the acoustic contribution is low in this configuration; the focus is on design)
-
50 mm air gap: NRC 0.70 / αw 0.70 – Class C (a solid absorption value)
Values from our own measurements to ISO 354 (reverberation room), rated to DIN EN ISO 11654; PET felt 9 mm, 1.9 kg/m², pressed wave shape. The wave's diffusion effect is an additional qualitative benefit and is not included in these metrics.
In practical terms: when the 3D-Wave is installed on battens or a support structure with an air gap of around 50 mm, it achieves solid Class C absorption in the mid- and high-frequency range – the range most important for speech intelligibility – and helps reduce reverberation time in accordance with DIN 18041. For the highest sound absorption classes, we recommend combining it with our flat acoustic panels or the nonwoven composite (Class A).
Applications
High-visibility surfaces: Reception and lobby walls, foyers, and showrooms – as statement walls with visual depth.
Hospitality: Design accents on walls and ceilings in hotels, restaurants, bars, and cafés.
Offices and conference spaces: Accent walls in meeting and conference rooms, focus and quiet zones, and acoustic pods.
Retail, medical practices, and wellness: Distinctive branded and reception walls, medical offices, clinics, and wellness areas.
Events and stages: Striking backgrounds and sets; media and home theater walls.
Colors, Order Quantity, and Delivery Time
The 3D-Wave is made from our 9-mm stock panels and is available in over 45 design colors from the 9-mm collection (see the full 9 mm collection). Colors can be freely mixed within an order.
-
Orders start at 20 panels per wave profile – colors can be freely combined
-
Smaller quantities starting at 10 panels are possible on request if we take the remaining panels from the batch into stock
-
Made-to-order item – delivery time approx. 7 weeks: The 3D-Wave is not supplied from stock; it is manufactured in the press from our 9-mm stock panels for your order
In addition to the three standard profiles W17, W18, and W19, custom shapes are also possible – from your own wave contour to a sculptural brand motif. A dedicated press mold is produced for this purpose; the customer contributes a share of the mold-making costs. From the second production run onward, we can manufacture cost-effectively using the existing mold. Contact us about projects with a distinctive design language.
Material and Manufacturing
The vitAcoustic PET felt panel is made from recycled PET plastic bottles, which are processed into textile fibers and laid into a fiber web using the needle felt process (nonwoven) – entirely without adhesives or chemical binders. The characteristic heathered appearance is created by mixing fibers of different colors. The recycled content is certified by SCS Global Services.
For the 3D-Wave, the flat 9-mm raw panel undergoes an additional step in which it is pressed into an aluminum mold in a heated press at a defined temperature and pressure. Depending on the wave shape, the material is compressed to approximately 4 mm at the pressure points, creating a consistently firm wave panel without a facing.
- Water-resistant and dimensionally stable in humid conditions
- Resistant to mold, pests, and dust mites
- Suitable for allergy sufferers – no volatile constituents
- Fully recyclable at the end of its service life
Fabrication and Installation
The 3D-Wave can be worked with standard tools (sawing, waterjet cutting, and CNC cutting with an oscillating knife, including freeform shapes). Various fastening systems are available depending on the application:
-
Adhesive mounting: e.g., UHU Polymax High Grip, UHU por contact adhesive, or double-sided adhesive tape (CT-S 5735)
-
Screws and staples: Particleboard screws, staple gun staples
-
With an air gap: Installation on battens/a support structure with an air gap of approx. 50 mm – recommended for the best acoustic performance
Cleaning and care: Vacuum or wipe with a damp cloth, as with textile coverings.
Certifications and Standards
