vitAcoustic 3D-Wave PET Felt Acoustic Panels – Thermally Formed Wave Design (Profile W17) 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 on walls and ceilings that plays with light and shadow while both scattering and absorbing sound.
The 3D-Wave is primarily a design product: its wave shape creates depth, movement, and a changing interplay 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 W17 mold – a distinctive, expressive wave with a strong interplay of light and shadow. You can find an overview of all three wave profiles below.
What Defines the 3D-Wave
Light, shadow, and depth: The sculptural wave breaks up incoming light and creates a dynamic play of shadows throughout the day. A flat wall becomes a statement surface with depth – ideal wherever a surface is intended to become a design focal point.
Diffusion as an added benefit: The wave geometry scatters incoming sound in several directions rather than reflecting it back in a single direction like a smooth wall. This distributes reflections more evenly throughout the room and reduces flutter echoes between parallel walls – the 3D-Wave thus acts as a combined absorber and diffuser.
Biophilic appearance: Wave- and hill-like forms feel organic and calming. Combined with LED lighting positioned along the sides or behind the panels, they create a particularly atmospheric play of light in the evening.
Wave Profile W17 and the Three Variants
This model uses the W17 mold: panel size 2400 × 1100 mm, wave height 14 mm, wave spacing 33 mm + 14 mm valley – a distinctive, expressive wave with a strong interplay of light and shadow.
The 3D-Wave is available in three wave profiles, each 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 a strong interplay of light and shadow
-
W18 – 2400 × 1200 mm | Wave height 7.5 mm | Spacing 36 mm + 1.5 mm valley – a subtle, fine wave for elegant, calm 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 crucial to achieving a good value. We report NRC and the 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 here; 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 chamber), rated to DIN EN ISO 11654; PET felt 9 mm, 1.9 kg/m², pressed wave shape. The wave's diffusion effect is a qualitative added benefit and is not included in these metrics.
In practice, this means that when the 3D-Wave is mounted on battens or a substructure with an air gap of approximately 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 spaces: Reception and lobby walls, foyers, and showrooms – as a statement wall with depth.
Hotels and 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 practices, clinics, and wellness areas.
Events and stage design: Striking backgrounds and stage sets; media and home theater walls.
Colors, Order Quantity, and Delivery Time
The 3D-Wave is manufactured 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 starting at 20 panels per wave profile – colors can be freely combined
-
Smaller quantities starting at 10 panels are available 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 but 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 mold is made 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 your own design language.
Material and Manufacturing
The vitAcoustic PET felt panel is made from recycled PET plastic bottles that 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 blending differently colored fibers. The recycled content is certified by SCS Global Services.
For the 3D-Wave, the flat 9-mm raw panel is pressed into an aluminum mold in an additional step using a heated press at a defined temperature and pressure. Depending on the wave shape, the material is compressed to approximately 4 mm at the pressing points, creating a wave panel that is firm throughout and has no laminated facing.
- Water-resistant and dimensionally stable when exposed to moisture
- 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 common tools (sawing, waterjet cutting, and CNC cutting with an oscillating knife, including freeform shapes). Various fastening systems are available depending on the application:
-
Adhesive bonding: e.g., UHU Polymax High Grip, UHU por contact adhesive, or double-sided tape (CT-S 5735)
-
Screws and staples: Particleboard screws, staples
-
With an air gap: Installation on battens/a substructure 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.
Certificates and Standards
Tested for harmful substances and low-emitting: Our PET acoustic panels are GREENGUARD Gold certified (UL 2818) and meet strict limits for indoor chemical emissions. Formaldehyde emissions are well below the requirements that apply throughout the EU from August 6, 2026 (REACH Annex XVII). In addition, the materials are tested for substances of health concern in accordance with OEKO-TEX Standard 100.
Fire performance even in freestanding applications: The 9-mm PET felt achieves Class B-s1,d0 (flame-resistant, EN 13501-1, TÜV SÜD) even when freely suspended or freestanding – without rear fastening – relevant for ceiling clouds, baffles, and room dividers.
