HD1007 Hush System HDC: economical sound insulation system between separating floors

The HD1007 system from Hush Acoustics is ideal for providing a high level of acoustic insulation in separating floors/ceilings constructed using a concrete structure at 400 kg/m² minimum. A relatively simple concept, its excellent performance characteristics are possible thanks to the quality of the Hush Acoustics insulation materials it utilises, particularly Hush Panel 28 for the creation of a floating floor.   

An economical and fully tested system, HD1007 Hush System HDC can be applied in new build, conversion or refurbishment projects and is fully compliant with the relevant UK Building Regulations - Approved Document E (England & Wales), Part G (Northern Ireland) and Section 5 (Scotland).

HD1007 is installed in the following way:

• Hush Panel 28, with all T&G joints glued using Hush Bond and all perimeters sealed using Hush Seal 20, is laid over 200mm in-situ concrete slab (400 kg/m2).
• Timber battens are fixed to the underside of the concrete at required centres.
• One layer of 12.5mm Gyproc Soundbloc or Fireline plasterboard is then secured to the timber battens and all perimeters are sealed prior to skimming.
