Description

The Acousdpc has been developed to offer vertical protection and complement the horizontal Acoustray and Acousformer systems in minimising flanking noise transmission along the cavity of an external cavity wall at the intersection of a party wall. It also operates fully as an effective fire barrier cavity stop and in conjunction with the polythene DPC has no risk of water penetration.

Where a party wall meets the cavity wall, Building Regulations stipulate the use of a mineral wool closer for sound insulation purposes. The NHBC requires that any such closer is protected by a suitable DPC. It has been developed to meet these requirements.

Features:

  • Complies with Building Regulations (E&W) Approved Document B and E.
  • Fully compatible with horizontal Acoustray.
  • Excellent sound insulation properties.
  • As a fire stop achieves four hours (240 minutes) fire integrity to BS 476- 20: 1987.
  • Cavity options available.
  • Self-supported by compression fit.
  • Easily installed.

Satisfies NHBC requirements. Complies with Building Regulations (E&W) Approved Document E Resistance to the passage of sound. Complies with Building Regulations (E&W) Approved Document B Internal fire spread (structure). Complies with Robust Details edition 2 (Jan 2005).
