  • Soundproofing against airborne noise in vertical walls with low surface density (lightweight partition walls or boards made of different materials).
  • When bonded between stiff rigid sheet materials it greatly reduces the resonance and coincidence dips.
  • When stapled over frameworks it greatly improves the overall performance of a lightweight partition.
  • When bonded to lightweight resonating metal panelling it greatly reduces vibration and re-radiated noise.
  • Combined with sound-absorbent materials, it offers extremely high acoustic performance.
  • Its applications in the industrial field range from the soundproofing of booths to the acoustic insulation of machine rooms, gutter pipes and sound damping of metal sheets, etc.

For further information see examples in systems sheets.

Installation Guidance

  • Ensure walls are clean and free from dust and debris
  • Cover entire area
  • Butt edges together
  • Tape seams
  • Seal edges and gaps with flexible sealant
