Description

The HD1057 Hush Wall System from Hush Acoustics provides the ideal solution for upgrading the acoustic performance of an existing masonry wall, typically of a bricks / block construction.


It is a class-leading system suitable for residential, commercial and public buildings whether they are new build, conversion and refurbishment projects.

  • Building Regulations Approved Document E (E&W), Technical Handbook Section 5 (Scotland) and Technical Handbook G (Northern Ireland) compliant.
  • A tried and tested thin solution to upgrade existing masonry walls.
  • Excellent acoustic performance levels using a thin acoustic wall lining system.


The HD1057 acoustic system combines a variety of Hush Acoustics sound insulation products, including Hush Slab 25, a high performance sound absorber which is applied directly to the masonry.

How it is installed


To maximise the performance of the HD1057 Hush Wall System, the various component parts must be installed in full to either side of the existing masonry as follows:


  1. Install Hush Bar Resilient Bars to both sides of the wall, insulating within the bars using Hush Slab 25 Sound Absorber.
  2. Face the resilient bars with the Hush Wallboard. Ensure the fixings attaching the Hush Wallboard to the Hush Resilient Bars do not penetrate through to the masonry.
  3. Finally, ensure the perimeters of the Hush Wallboard are sealed using the Hush Heavy Duty Isolation Tape and the Hush Acoustic Sealant as per the Hush Wall System data sheet.
