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

Waffel is an acoustic panel made of Basotect, a fibre-free melamine resin foam, with a waffle structure on one face for direct bonding to ceilings and walls. Alongside the standard version, the range includes the more finely structured Waffel Mini and the water- and oil-repellent Waffel H. The panel is intended for surfaces where low weight and a shallow build-up are required, for example in production facilities and recording studios.
