Home > Companies > Siderise Group > SIDERISE CW-AB Acoustic Barrier Overlay - Facades (formerly Lamatherm CW-AB)

A flexible acoustic composite for use as a mass overlay within curtain walling to form a high performance sound barrier. They represent a simple solution to the problem of improving 'floor-to-floor' acoustic performance when used in conjunction with SIDERISE CW-FS Perimeter Barriers and Firestops for Curtain Walling (formerly Lamatherm CW-FS fire and smoke stop for curtain walling).

SIDERISE Acoustic Barriers are extremely quick and easy to install and are suitable for improving sound performance within all curtain walling environments. Being flexible and thin, they are ideal for curtain wall application as unlike rigid boards or partitions, SIDERISE Acoustic Barrier Overlay is designed to accommodate façade deflection.

Features:

  • Accommodates façade movement.
  • Available in strip or sheet form for site cutting.
  • Deforms to contours.
  • Ideal for remedial treatment after installation of fire stops.
  • Quality assured to BS EN ISO 9001.
  • Reduces 'floor-to-floor' sound transmission.
  • Very flexible, easily cut and shaped on site.
