Applications

• Soundproofing against airborne noise in vertical walls with low surface density (lightweight partition walls or boards made of different materials).
• Soundproofing against airborne noise in ceilings and lightweight roofs
• Reduction of impact noise level in all types of floors, sandwiched between floor slabs and loose-laid flooring.
• Damping of impact noise caused by rain or hail on metal decks.
• Combined with sound-absorbent materials, it offers products with high acoustic performance.
• Can be used to dampen resonance on the thin metal bodywork of cars and other types of machinery.
