product description
FLORA Cgreen silence in a modern form
The FLORA C Sound-Absorbing “Green Wall” Acoustic Panel is one of the most popular and versatile solutions on the noise protection market. It combines high sound attenuation performance with a distinctive aesthetic that allows the structure to be naturally covered with climbing plants.
This is a solution that not only reduces noise but also blends harmoniously into its surroundings – from road infrastructure to urban and private developments. FLORA C panels are precisely adapted in width to standard HE 160 steel columns, with the possibility of installation in columns with larger cross-sections.
Construction: steel frame made of cold-formed profiled channel sections joined using a tongue-and-groove system, steel mesh made of Ø6 mm rod with a 150×150 mm grid, all components protected by hot-dip galvanizing (average 90 µm), infill of two layers of acoustic mineral wool separated by roofing felt. The panels hold a KOT Certificate (IBDiM) and CE marking (TSÚS).
