The Green Wall FLORA C absorbing acoustic panel is one of the most popular noise protection solutions on the market.
The panel is made up of a steel frame made of horizontal cold-formed C-profiles connected by a tongue and groove system. The frame has a 6 mm dia. rod grid welded on, with a mesh size of 150 mm x 150 mm. All steel components are abrasion-treated and then corrosion-protected by hot-dip galvanisation with a coating thickness of 90 µm. This guarantees high product durability. Inside there are two layers of acoustic insulation wool of a specific thickness and density, separated by felt. The green, light grey or dark grey colour is conveyed by the PE mesh and technical fabric placed between the steel mesh and the wool. Due to the acoustic layers of the fill and the acoustic parameters, we differentiate between three panel types:
- Flora C type C3 – the most commonly used panel
- Flora C type C4 – increased insulation capacity panel
- Flora C type C6 – significantly increased insulation capacity panel
The standard panel height is up to 2000 mm – whereby it may be increased even up to 4000 mm if pillars are spaced at 2000 mm. Please note that the top panel length is 6000 mm.
The Flora C type panels are adapted to standard HE160 I-beams in terms of width. It is possible to install them in larger I-beams.
Our panels have all the necessary documents confirming their quality KOT issued before IBDIM and CE issued by the TSUS.
