# What Fabric Is Best for Acoustic Panels?
Selecting the right fabric for acoustic panels is crucial for optimal sound absorption, durability, and aesthetics. Professionals in sound insulation materials need high-performance fabrics that balance acoustics, fire safety, and design flexibility. Below, we break down the best options and key considerations.
Top Fabrics for Acoustic Panels
1. Guilford of Maine FR701
- Material: 100% polyester
- Key Features:
- High NRC (Noise Reduction Coefficient) rating (0.70–0.95)
- Fire-resistant (meets ASTM E84 Class A standards)
- Breathable, allowing sound waves to penetrate the absorber core
- Wide color selection for design versatility
2. Wool Felt
- Material: Natural or synthetic wool blend
- Key Features:
- Excellent mid-to-high-frequency absorption
- Eco-friendly option (if natural wool)
- Dense structure enhances durability
3. Polyester Fiber (PET Felt)
- Material: Recycled polyethylene terephthalate
- Key Features:
- Lightweight yet effective for broadband absorption
- Sustainable (made from recycled plastics)
- Resistant to moisture and mildew
4. Burlap (Hessian Fabric)
- Material: Jute or hemp fibers
- Key Features:
- Cost-effective and breathable
- Best for low-budget projects with moderate acoustic needs
- Less durable than synthetic alternatives
5. Acoustically Transparent Fabric (e.g., Speaker Cloth)
- Material: Polyester or polypropylene blends
- Key Features:
- Minimal sound wave obstruction (ideal for speaker covers)
- Stretchable for seamless panel wrapping
Key Selection Criteria
1. Acoustic Transparency
- The fabric must allow sound waves to pass through to the absorber core.
- Test with a blow test – if air passes easily, it’s acoustically transparent.
2. Fire Resistance
- Look for ASTM E84 Class A or European EN 13501-1 certifications.
- Critical for commercial and public spaces.
3. Durability & Maintenance
- High-traffic areas need abrasion-resistant fabrics (e.g., polyester blends).
- Stain-resistant coatings improve longevity.
4. Aesthetic Flexibility
- Custom colors, patterns, and textures enhance design integration.
Industry Insights & Data
- According to a 2022 study by the Acoustical Society of America, polyester-based fabrics retain acoustic performance longer than natural fibers due to moisture resistance.
- Fire-rated fabrics reduce insurance costs in commercial installations (NFPA 101 compliance).
Final Recommendations
- Best Overall: Guilford of Maine FR701 (performance + safety)
- Budget Pick: Burlap (for low-impact areas)
- Eco-Friendly Choice: Wool felt or PET felt
