Merfocell NOP
Weighted sound absorption coefficient up to αw = 0.80
Available with or without self‑adhesive backing
Resistant to water, oil, fuels, and many cleaning solvents
Merfocell NOP is a sound-absorbing panel made from open-cell polyurethane foam with a studded surface, which enhances sound absorption, primarily in the mid- and high-frequency ranges (above approximately 1,000 Hz). It is ideal for applications where both aesthetics and acoustic control are required. The panel is available with a self-adhesive backing or as a non-adhesive variant for flexible installation.
Merfocell NOP panels are available in 30 mm or 50 mm thicknesses and in a standard size of 1,200 × 1,000 mm, with custom sizes available on request. The foam has a density of approximately 26 kg/m³, and sound absorption is tested according to EN 354. The material is temperature-resistant up to around 100 °C, with the self-adhesive backing rated up to 70 °C. The panel is resistant to water, oil, fuels, and common cleaning products and maintains its performance after drying.
Merfocell NOP is suitable for recording and voice-over studios, ventilation ducts, computer housings, machine and equipment enclosures, and other technical spaces where high-frequency sound absorption and a decorative, protective finish are required. It is also suitable for industrial and maritime environments where fire safety, CE compliance, and durability are essential.

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