FOMEX FLAT – Fire Resistant Acoustic Foam Panel

FOMEX FLAT is a high-density fire-resistant acoustic foam panel designed to deliver superior sound absorption in challenging environments. Manufactured from advanced polyurethane foam, it offers exceptional performance across medium and high-frequency ranges, ensuring a balanced and controlled sound environment.
With its smooth surface and sleek dark-grey finish, FOMEX FLAT provides both technical efficiency and visual refinement. Engineered to withstand high temperatures without melting or deforming, this acoustic solution offers reliable performance for industrial, commercial, and architectural applications where safety and durability are critical.
Available in standard thicknesses of 10 mm and 20 mm, FOMEX FLAT is lightweight, flexible, and easy to integrate into various surfaces, from walls and ceilings to ducts and machinery enclosures.
How It Works
The open-cell structure of the polyurethane foam captures airborne sound waves, dissipating them as low-grade heat through internal friction. This process reduces reverberation and prevents the build-up of reflected sound energy.
Thanks to its high material density (75–110 kg/m³), FOMEX FLAT effectively absorbs mid and high-frequency sounds while providing moderate insulation values. The material’s fire-resistant composition ensures stability even under elevated thermal conditions, offering a safe and long-lasting acoustic solution.
Key Benefits
- Provides excellent absorption of mid and high-frequency sounds.
- Fire-resistant construction ensures long-term safety and performance.
- Lightweight and easy to cut, handle, and install.
- Durable polyurethane foam maintains shape and density over time.
- Smooth surface offers clean integration into any interior or industrial design.
- Customisable dimensions and shapes for specialised applications.
Installation Overview
FOMEX FLAT panels can be securely mounted using DECIBEL’s recommended installation adhesive or other industrial-grade bonding systems. The lightweight foam allows for quick installation on walls, ceilings, and duct interiors without requiring complex tools or structural reinforcement.
