3D Polyester Acoustic Panels for Modern Interiors
Decorative PET panels that reduce echo and improve speech clarity.
Decrasound 3D Polyester Acoustic Panels
Decrasound™ 3D wall panels bring visual depth to interiors while improving room acoustics.
Made from PET polyester fibre (typically with high recycled content), these sculpted panels provide
reliable sound absorption without compromising design intent. They suit feature walls, meeting rooms,
classrooms, studios, and reception areas where echo and background noise make conversations hard to follow.
With a choice of geometric and flowing profiles, matte or felted finishes, and practical installation
options, 3D polyester panels offer a neat way to reduce reverberation, support better focus, and present
a neat, durable surface that’s easy to maintain.
Key Features
- Sound-absorbing PET polyester with durable, low-maintenance finish.
- Three-dimensional patterns for a striking architectural effect.
- Good acoustic performance (final results depend on thickness, backing and air-gap).
- Suitable for offices, schools, hospitality, retail and studios.
- Simple installation: adhesive, mechanical fixings or sub-frame.
Typical Applications
- Feature walls in lobbies, corridors and reception areas.
- Meeting rooms and open-plan offices to reduce echo and distraction.
- Lecture theatres, libraries and multi-purpose halls.
- Studios and creative spaces needing broadband absorption.
3D Polyester vs Other Panel Types (Quick Comparison)
| Panel Type | Material | Look | Acoustic Use | Notes |
|---|---|---|---|---|
| 3D Polyester Panels | PET polyester | Sculpted 3D profiles | Broadband absorption (varies by thickness/air-gap) | Decorative feature walls with real acoustic benefit |
| Flat PET / Decrasound Panels | PET polyester | Clean, minimalist | Good absorption for walls/ceilings | Cost-effective coverage for large areas |
| Serenity Fabric Panels | Core with fabric finish | Fabric textures/colours | High absorption; custom sizes | Ideal for boardrooms and classrooms |
| Murano Timber Panels | Perforated/slot timber | Warm timber aesthetic | Tuned absorption/diffusion | Great for premium interiors |
Installation Guidelines
- Prepare surface: Clean, flat, and dry substrate.
- Set out: Dry-lay to align 3D profiles across joins.
- Fix: Use suitable adhesive or mechanical fixings; a 10–30 mm air-gap can improve low-frequency results.
- Finish edges: Shadow gaps or trims keep lines neat.
- Verify: For critical rooms, measure reverberation time after install.

Frequently Asked Questions
What are 3D polyester acoustic panels?
They are PET polyester panels formed into three-dimensional shapes to deliver sound absorption with a decorative surface suitable for public and commercial interiors.
How effective are they?
Performance depends on thickness, backing and any air-gap. In practice they provide broad-spectrum absorption that reduces echo and improves speech clarity.
Where should I use them?
Feature walls in offices, schools, hospitality and reception areas. They pair well with ceiling baffles and flat wall panels for complete coverage.
How are they installed?
Panels can be adhered directly, mechanically fixed, or mounted on a sub-frame. A small air-gap behind the panel can improve low-frequency results.
Are they suitable for fire-regulated spaces?
Panels can be specified to meet relevant fire-safety standards. Confirm the required rating for your project and jurisdiction.
Decrasound 3D Wall Panels
Creative interior design and effective sound absorption sometimes can be difficult to achieve with a single product. Most acoustic treatments are thin two dimensional panels and hence have limited creative potential. Decrasound 3D Panels provide a dynamic alternative to these conventional rectangular acoustic panels. These efficient decorative sound absorbers are moulded or shaped into three dimensional patterns that include waves, blocks and many other exciting designs.
Decrasound 3D acoustic panels are manufactured from 100% polyester fibre (PET) and contain a minimum of 75% recycled material. They are available in a smooth matt finish, or a fibre felt finish. Decrasound 3D Panels have excellent acoustic properties, so are ideal in spaces like Studios, Schools, Auditoriums or Offices.
