Summary
The INSA AL 114 metal noise barrier represents the natural evolution, compared to steel, offering superior resistance to oxidation and long-term degradation.
Its structure, made of aluminum with a rock wool core, makes it an even lighter option without compromising its high insulation and acoustic absorption properties. The INSA AL 114 is the optimal solution when lightness, durability, and corrosion protection are required. It is ideal for highly corrosive or humid environments, such as coastal areas or critical infrastructure.
Installation is typically done by embedding it into HEAA profiles, ensuring a stable and secure fix. It is available painted in the RAL color range, with RAL 6009 (fir green) being the most common.
