HD1009 Hush System B/B

HD1009 Hush-System BB provides an effective acoustic insulation solution for concrete separating floors created using beam and block.

It is an economical and simple system that is fully tested to deliver excellent sound insulation in new build and refurbishment projects.

The performance of HD1009 is achieved through a design that disrupts sound paths through separation and the use of high quality materials including Hush-Panel 28 - a high mass acoustic floorboard. 

HD1009 Hush-System BB is compliant with the UK Building Regulations relating to acoustic insulation - Approved Document E (England & Wales), Part G (Northern Ireland) and Section 5 (Scotland). 

How the HD1009 system is formed:

• Hush-Panel 28, with all tongue and groove joints glued using Hush-Bond and sealed at all perimeters using Hush-Seal 20, is laid over 50 mm screed, with a 260 kg/m² beam and block concrete below.
• Timber battens are fixed to the underside of the concrete at required centres.
• One layer of 12.5 mm Gyproc Soundbloc or Fireline plasterboard is then secured to the timber battens.
• All perimeters are then sealed prior to skimming.
