MAGNUM AL12 high noise absorption panel

🛡️ MAGNUM AL12 – High-Performance Aluminium Acoustic Panel

The MAGNUM AL12 is a metal 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 1.2 mm thick aluminum, it combines very high sound absorption, natural corrosion resistance, and long-term durability, including in aggressive environments such as coastal areas, tunnels, or industrial zones.

⚙️ Technical specifications

• Material: aluminum, 1.2 mm thick (solid or perforated surface depending on the project)

• Filling: high-density rock wool (≈ 60 kg/m³) with mineral fleece on the road-facing side

• Top cover: plastic (PP) or aluminum, clipped or crimped depending on the model

• Installation: compatible with HEA 140 / 160 / 180 mm posts

• Average weight: approx. 30–36 kg/m² depending on configuration

• Finish: raw aluminum or optional RAL powder coating

• Standard dimensions: L = 4,000 mm; H = 500 or 1,000 mm (other sizes on request)

💡 The aluminum used does not require galvanizing, which simplifies maintenance while ensuring excellent resistance to weather and oxidation.
