Used in many varied applications and industries including construction, marine, automotive, and OEM.

Some applications use the product as a component layer within a bespoke Siderise composite material. The barrier is then optionally combined with sound absorbents, spacing layers, facings, and self-adhesive backings.

Common construction applications include high-performance wall and partition constructions; overlays to timber intermediate floors; cladding to external ducts/ pipes and for temporary screens on construction sites.


Combining a high surface mass with ‘limp’ mechanical characteristics, Siderise BM series barrier mat: BM0100 offers optimum acoustic performance. Primarily designed to improve the sound insulation value of existing panels of metal, wood, plastic, GRP, etc. It is particularly effective in reducing the effect of coincidence dip resonance found in these stiff, lightweight materials. Additionally, Siderise BM series barrier mat: BM0100 may be used:

  • On its own as a flexible void closure material; in sandwich constructions between boards.
  • As a membrane in frequency selective sound absorbers.
  • As an overlay treatment to materials or constructions with perforations or minor gaps resulting in potential sound leakage.

The product is robust, clean & simple to use and can be readily cut to size with a sharp knife.

Siderise BM series barrier mat: BM0100 can be used in multiple offset layers which both increases the total applied mass and negates the normal requirement for overlap joints to maintain acoustic integrity.

Features and benefits:

  • High acoustic performance.
  • Thin and flexible.
  • Reduces ‘coincidence dip’.
  • Low cost unsupported option.
  • Inherent fire resistance.
  • Low odour.
