Fural Soft Akustik

Fural Soft Akustik is Fural's brand for sound absorbers: ceiling rafts, baffles, acoustic panels, wall absorbers, inserts for grid ceilings and the seamless acoustic plaster phonestop V, mostly made of melamine resin foam and PET. The products come from the former pinta acoustic, whose machines, test reports and many employees Fural took over.

Description

Absorber Linear is a lamella absorber for ceilings with concrete core activation, in which strips of melamine foam (Basotect) in several heights are bonded into aluminium carrier profiles, either with joints or butt-jointed. The profiles run in rows directly on the soffit, and because the lamellas cover only part of the ceiling area, they have little effect on the cooling performance of the slab. It is used in office and administration buildings, meeting rooms, and exhibition and assembly venues.
