🛡️ MAGNUM AL15 – High-performance aluminium noise barrier panel
The MAGNUM AL15 is a metallic noise barrier panel developed by UNIPROMET and distributed by SOLOSAR, designed to reduce noise pollution along roads, highways, railways, or in industrial environments.
Made from 1.5 mm thick aluminium, it combines very high acoustic absorption with natural corrosion resistance and long-term durability, even in harsh environments (coastal areas, tunnels, industrial sites).
⚙️ Technical specifications
Material: aluminium, 1.5 mm thick (solid or perforated face depending on project)
Core: high-density rock wool (≈ 60 kg/m³), with mineral fleece on road-facing side
Top cover: plastic (PP) or aluminium, clipped or crimped depending on the model
Mounting: on HEA posts 140 / 160 / 180 mm
Average weight: approx. 30–36 kg/m² depending on configuration
Finish: raw aluminium or optional RAL powder coating
Standard dimensions: L = 4,000 mm; H = 500 or 1,000 mm (other sizes on request)
