Description

Flamex PU is a flat melamine foam panel designed to absorb unwanted sound reflections and reduce reverberation. Its lightweight open-cell structure improves acoustic clarity and speech intelligibility. The material withstands temperatures from -43 °C to +150 °C and is resistant to moisture, oil, and cleaning products, making it suitable for commercial, educational, and industrial applications. Panels are available in the standard size of 1,200 × 600 mm and in multiple thicknesses to suit different performance requirements.

Properties

The Flamex PU panel provides a sound absorption coefficient up to αw = 0.80 when properly installed. It also offers thermal insulation with a thermal conductivity of λ ≈ 0.033–0.037 W/(m·K), contributing to both acoustic and thermal performance. Safety is ensured according to EN 13501‑1 Class C, with smoke production s₂ and droplet formation d₀. The non-fibrous foam is lightweight, easy to cut to size, and can be quickly mounted with water-based adhesives.

Applications

Flamex PU is ideal for offices, studios, call centers, classrooms, public spaces, and industrial environments where acoustic optimization is required. Its easy installation on walls and ceilings, combined with a 24-hour acclimatization period, makes it suitable for both renovation and new construction projects.

Answers to common questions

Answers to the most common technical and practical questions.
Can the acoustic performance be predicted for a specific space?

Merford can perform acoustic analyses or simulations to predict noise levels and reverberation times based on material selection, room dimensions, and finishes, ensuring the right solution is designed.

How maintenance-friendly are these materials?

Our acoustic materials generally require minimal maintenance. Dusting and cleaning is usually sufficient to maintain long‑term performance.

What is the difference between vibration isolation, sound insulation, and sound absorption?
  • Vibration isolation reduces mechanical vibrations from machines or equipment, preventing transmission to the building structure or floor.
  • Sound insulation prevents sound from passing from one space to another, e.g., between rooms or to the exterior.
  • Sound absorption reduces echo and reverberation within a space by damping sound waves, improving comfort and speech intelligibility.

Merford materials can provide one or more of these effects depending on the product type, such as absorption panels for rooms or isolation around ventilation units.
