Application

Suitable for use in new build, conversion and refurbishment developments where a block stud wall is used. Can be used in domestic, commercial and public buildings.

Description

The HD1056 Block Acoustic Cavity Wall System is ideal for soundproofing cavity walls in new build, conversion and refurbishment projects.


A simple yet tried and tested acoustic system, it creates a dense block cavity masonry wall with excellent acoustic performance due to the mass of the blocks and the clear 100mm cavity, working together with Soundbloc plasterboard sealed with Hush Acoustic Sealant.


This combination works together to deliver an effective result that is compliant with all relevant UK Building Regulations - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland).


How HD1056 is formed:


  • Construct a block cavity wall from two dense concrete blocks at a density of 1900 kg/m3 minimum.
  • Create a clear 100mm gap between both 100mm block walls (this gap should remain clear of mortar snots at all time).
  • Face both sides of the masonry walls with 15mm Soundbloc Plasterboard.
  • Seal the perimeters of the plasterboards with Hush Acoustic Sealant.


Features and benefits:


  • Can be used in new build, conversion and refurbishment developments.
  • Building Regulations Approved Document E (England & Wales), Technical Handbook Section 5 (Scotland) and Technical Handbook G (Northern Ireland) compliant.
  • Excellent acoustic performance.
