MP Perforated Metal Sound Barriers: Innovative Soundproofing & Sound Absorption Solutions
Introduction
The MP Perforated Metal Sound Barriers are one of the most advanced soundproofing solutions, combining high sound insulation and sound absorption performance. They are designed to withstand demanding conditions, providing noise reduction of up to 37 dB while ensuring aesthetic harmony and structural strength.
They are widely used in both exterior and interior spaces, such as highways, factories, buildings with high acoustic protection requirements, and facilities where noise shielding from machinery is necessary.
How Do Perforated Metal Sound Barriers Work?
The MP Perforated Metal Sound Barriers rely on two main mechanisms for noise reduction:
- Sound Absorption: The perforated metal sheet allows sound waves to enter the sound-absorbing material inside the barrier. There, the sound waves are converted into thermal energy, reducing their intensity.
- Sound Reflection: The back of the barrier is made of a solid metal sheet that reflects the sound back to its source, reducing its spread in the protected area.
This combination allows the MP panels to perform excellently in areas with high noise pollution.
Construction & Technical Features
The MP Perforated Panels are manufactured with modern, automated processes, ensuring precision and durability.
- External Surface: Galvanized steel sheet with micro-texture, coated with a 25 μm polyester paint, providing excellent weather protection.
- Internal Surface: Perforated galvanized steel sheet (0.6 mm thick), painted with the same polyester coating for optimal sound absorption.
- Core: High-density rock wool (90-100 kg/m³) with vertically oriented fibers for maximum sound absorption.
- Panel Thickness: Available in 50, 60, 80, 100, 120, 150, 200 mm.
- Weight: From 14 kg/m² to 31.5 kg/m², depending on thickness.
- Connection: Male-female system (tongue & groove), ensuring sound tightness and increased static strength.
- Fire Reaction: Classification A2-s1-d0 (non-combustible) according to EN 13501-1.
- Temperature Resistance: From -5ºC to +180ºC.
- Waterproofing: Non-hydrophilic material, resistant to moisture.
Installation
The installation of the MP Panels is fast and flexible:
- Installed by sliding into HEA-type metal profiles, stabilized on the ground.
- Vertical support at the top and bottom or screwing into a metal frame, according to static requirements.
- Easy transport and adjustment to meet the needs of each project.
Applications
The MP panels are ideal for a wide range of applications, such as:
- ⚡ Machine Fencing – Shielding air conditioning units, transformers, and cooling towers.
- 🏗 Industrial Installations – Noise reduction from machines and factories.
- 🚧 Road Networks – Protection of residential areas from traffic noise.
- 🏥 Hospitals & Schools – Creating quiet environments in noise-sensitive spaces.
- 🚆 Railways – Reducing noise pollution from passing trains.
- 🔥 Fire-resistant Applications – Suitable for garages, hazardous material warehouses, and high-fire-risk buildings.
Conclusion
The MP Perforated Metal Sound Barriers are a reliable, durable, and effective solution for noise reduction in both exterior and interior spaces. Their resistance to weather conditions, easy installation, and high soundproofing capability make them a top choice for projects with high sound protection requirements.
