✖ Requires more maintenance compared to synthetic materials

Best Applications:

• Concert halls and auditoriums requiring acoustic performance with elegant aesthetics
• Luxury hotels and restaurants
• Corporate boardrooms where aesthetics and function matter

1.5 Polyester Fiber Acoustic Ceiling Panels

Composition:

Made from compressed polyester fibers, often derived from recycled plastic bottles, making them an صديق للبيئة acoustic solution.

Key Features:

• NRC: 0.60 – 0.90
• Flame-retardant and moisture-resistant
• Available in a variety of colors and designs

المزايا:

✔ Excellent sound absorption for mid and high-frequency noises
✔ Lightweight and easy to install
✔ Non-toxic and environmentally friendly
✔ Customizable in shape and color

العيوب:

✖ Less effective for low-frequency sound absorption
✖ May require additional treatment in very noisy environments

Best Applications:

• Office environments to reduce noise pollution
• Schools and educational buildings
• Home theaters and gaming rooms

1.6 Foam Acoustic Panels (Polyurethane or Melamine)

Composition:

Foam panels are made from polyurethane or melamine foam, often molded into pyramid, wedge, or egg-crate shapes to enhance sound absorption.

Key Features:

• NRC: 0.70 – 1.00
• Low-density and flexible
• Available in self-adhesive formats for easy installation

المزايا:

✔ Budget-friendly acoustic solution
✔ Excellent absorption of mid-to-high frequencies
✔ Easy to install and remove

العيوب:

✖ Not highly durable; prone to wear and tear
✖ Lower fire resistance unless treated

Best Applications:

• Home recording studios and podcast rooms
• Gaming setups and home theaters
• Rehearsal spaces and small performance venues

1.7 Gypsum Acoustic Ceiling Panels

Composition:

مصنوعة من calcium sulfate dihydrate (gypsum) and sometimes combined with sound-absorbing layers for improved performance.

Key Features:

• NRC: 0.50 – 0.80
• Highly fire-resistant
• Heavy-duty and impact-resistant

المزايا:

✔ Provides good acoustic performance in large spaces
✔ Resistant to fire and high temperatures
✔ Long-lasting and durable
