Solflex soundproof slat wall

Type: DGF 280mm

Technical description :

Professional noise reduction is achieved through soundproofing louvers, manufactured from Magnelis as standard. Upon customer request and for an additional charge, the soundproofing louvers can be powder-coated in RAL colors.
The soundproof louvers are filled with acoustically absorbing material (non-combustible fiberglass panels with abrasion-resistant and rain-repellent glass silk coating on the perforated sheet metal side d=1mm) for maximum noise reduction and are manufactured in a frame (d=1.5mm).
The distance between the soundproofing louvers is 150mm.
