PET Felt vs Traditional Acoustic Materials: Which One Is Better?
This comparison helps buyers understand performance differences, installation complexity, and cost considerations before making a specification decision.

PET Felt vs Traditional Acoustic Materials: Which One Is Better?
Common Comparison Materials
- PET felt panels
- Mineral wool boards
- Fabric-wrapped fiberglass panels
- Wood slat acoustic systems

1. PET Felt Panels
- Lightweight
- Easy to CNC cut
- Modern appearance
- Recyclable material
- Offices
- Commercial interiors
- Decorative acoustic applications
2. Mineral Wool / Fiberglass Panels
- Strong absorption performance
- Good for high acoustic demand
- Requires fabric wrapping
- Heavier
- More complex installation
3. Wood Slat Acoustic Panels
More comparison details
Criteria | PET Felt Panels | Mineral Wool / Fiberglass Panels |
|---|---|---|
Raw Material | Recycled PET bottles (post-consumer) | Mineral fibers / glass fibers |
Sustainability | High – recyclable, supports ESG & green building goals | Limited – difficult to recycle, energy-intensive production |
Health & Safety | No fiber shedding, non-irritating, safe to handle | Fiber dust may cause skin & respiratory irritation |
VOC Emissions | Low VOC, suitable for indoor environments | Depends on binder; potential VOC emissions |
Acoustic Performance | NRC up to 0.85–0.90 (depends on design & installation) | High NRC, typically 0.80–1.00 |
Weight | Lightweight, easy to transport and install | Heavier, fragile edges, harder to handle |
Installation | Easy cutting, mounting, and customization | Requires protective handling during installation |
Durability | Stable over time, no crumbling or sagging | Can deteriorate, compress, or shed fibers |
Design Flexibility | 3D shapes, colors, CNC cutting, custom sizes | Limited options, mostly hidden applications |
Maintenance | Low maintenance, cleanable surface | Surface damage and fiber exposure over time |
Application Areas | Offices, commercial spaces, hospitality, education | Mainly ceilings or concealed acoustic layers |
Cost Structure | Competitive total cost (material + labor savings) | Lower material cost, higher handling & labor costs |
Which One Should You Choose?
- Echo control + modern design → PET felt
- High-performance acoustic engineering → Fiberglass system
- Decorative wood look → Slat system
