Application

Suitable for use on timber stud, metal stud, brick and block walls.

Description

The HD1040 Hush Wall System is a highly versatile solution for providing acoustic insulation in timber stud, metal stud, brick and block walls, delivering a high standard of airborne sound reduction.


It is tested as a complete system and fully compliant with all UK Building Regulations - Approved Document E (England & Wales), Part G (Northern Ireland) and Section 5 (Scotland).


HD1040 is ideal for transforming sound insulation levels in different separating wall constructions, with an innovative design to reduce both flanking and direct sound transmission with only a minimal loss of space in the room. Key to this is the incorporation of a composite three layered board (1800mm x 900mm x 27mm) and a resilient bar system.


Key features and benefits:


  • Building Regulations Approved Document E (E&W), Technical Handbook Section 5 (Scotland) and Technical Handbook G (Northern Ireland) compliant.
  • High standards of airborne sound reduction.
  • Can reduce both flanking and direct sound transmission.
  • Minimal loss of space.


How the system is formed:


  • Hush-Wall Boards are fitted with all gaps filled using acoustic mastic and sealed at all perimeters with Hush-Isolation Tape, fixed horizontally to Hush-Bar Resilient Bars with 32mm dry wall screws.
  • Hush-Slab 25, or thickness to suit, is fitted into cavity between studs or tightly between Hush-Bars when applying to brick or block
  • Hush-Bar Resilient Bars are then fixed horizontally at 450mm centres to stud or wall, to allow for scrim joints and all perimeters to be sealed prior to skimming.
