Description
The soundSTOMP acoustic panel is a CNC-cut absorber made of Basotect G+, the open-cell melamine resin foam from BASF (8.5 ± 1.5 kg/m³). Panels in 1000 × 500, 500 × 500 and 1150 × 500 mm, optionally with a 45° decorative chamfer, in light grey, white and black; material thicknesses from 5 to 100 mm as well as special shapes, contours and fabric covering from 50 × 50 mm. The sound absorption follows the established BASF material curves for Basotect (Technical Information “Acoustics Basotect G”, reverberation room per DIN EN ISO 354), with a complete third-octave curve for each material thickness, from class D (20 mm) to class A (60 mm). As a suspended baffle system (type J) the material was additionally measured by TÜV Rheinland LGA. Reaction to fire C-s2,d0 per DIN EN 13501-1, documented by MPA NRW classification report 230008744-6.
