METAL MUTE

METAL MUTE is an advanced acoustic barrier system designed to deliver both effective sound attenuation and high-performance sound insulation in outdoor environments. It is ideally suited for residential and commercial applications, including terraces, rooftops with mechanical equipment, and other noise-sensitive areas.

Engineered for durability and performance, this aesthetically refined metal barrier is available in a range of colours and is specifically designed to withstand ultraviolet radiation, water exposure, and demanding outdoor conditions.

The system features a modular design, primarily composed of acoustic sandwich panels supported by a robust galvanised steel frame. The panels are constructed from high-quality aluminium, rockwool insulation, and a breathable fabric layer, ensuring optimal acoustic performance and long-term reliability.

All components are painted with electrostatic powder coating for enhanced protection and longevity, to meet project requirements and environmental conditions.

TECHNICAL DATA

TECHNICAL SPECIFICATIONS

INSTALLATION

Installation is achieved through mechanical fixing to walls or ceilings, or by mounting as noise barriers within a steel frame structure.

STRUCTURAL DESIGN

Structural design and load calculations are carried out in accordance with applicable standards, including CYS and relevant international codes, as detailed in the project-specific engineering report.

TECHNICAL DOCUMENTATION

Comprehensive technical documentation is provided, including product brochures, material inspection reports, and certification of specifications for all system components.

WEATHER-COASTAL CONDITIONS

The system is designed for durability in outdoor environments and is suitable for use in demanding weather and coastal conditions.

MAINTENANCE

The system requires minimal maintenance and can be easily cleaned using a soft brush, vacuum cleaner, or a damp, well-wrung cloth.

FIRE-RESISTANCE RATING

Available with fire classification ratings of A2-s1,d0 or B-s1,d0, in accordance with relevant European standards.

Additional PROPERTIES

High resistance to ultraviolet (UV) radiation , Recyclable materials , Optimized weight-to-surface ratio for efficient structural performance.

Supporting structure

The barrier system is supported by a galvanised steel framework, constructed using structural hollow sections (SHS), steel plates, and high-grade fastening elements. The modular design allows each barrier panel to be securely installed by sliding it into position above the preceding panel, ensuring ease of installation, structural stability, and precise alignment.

ACOUSTIC SPECIFICATIONS

Sound reduction (performance)

Rw = 31dB [According to ISO 10140-2, ISO717.1]

Sound absorption (performance)

Sound Class A (a_w=0.9) [According to ISO 11654:1997]

Sound attenuation (of the system)

The acoustic performance of the system depends on barrier height, length, and configuration, as well as the relative positions of the noise source and receiver. Expected sound attenuation levels are determined through project-specific acoustic studies and simulations to ensure optimal performance for each application.
