SOPREMA TECSOUND CLG 3900
TECSOUND CLG 3900 is a single-component acrylic compound used as a soundproofing material for walls and ceilings. TECSOUND CLG 3900 acts as a decoupling material using mass-spring-mass principle by changing the vibration frequency of the assembly, reducing the transmission of airborne noise (ASTM E90) and impact noise (ASTM E492).
