Aluminium Acoustic Panels
Maximum acoustic performance with minimal structural weight.
product description
FLORA ALUthe ALUMET system
The ALUMET system has been engineered for long-term performance, high resistance to weather conditions, and compliance with stringent safety standards — across road, industrial and railway infrastructure.
Available in three variants: ALUMET 1 (single-side sound-absorbing), ALUMET 2 (double-sided sound-insulating) and ALUMET 3 (double-sided sound-absorbing, maximum attenuation from both sides).
The panels are made of high-quality aluminium, fixed to top and bottom profiles with a tongue-and-groove system, with a standard height of 500 mm and a maximum length of up to 5,000 mm. They hold the IBDiM Technical Approval and CE marking confirmed by TSÚS.
