Description

The phonestop V acoustic panel consists of sintered expanded glass granulate made from recycled glass without binders and is fully bonded to walls or ceilings with no substructure and no cavity. The purely mineral panel is used indoors and outdoors in new build and refurbishment, for example in offices, schools, stairwells, swimming pools and industrial halls, in underground car parks, tunnels and railway stations, and on noise barriers. For surfaces without visible panel joints, there is the variant phonestop V fugenlos with an acoustic plaster finish.
