HD1014 Hush System 2003 Overlay

HD1014 Hush System 2003 Overlay provides an effective sound insulation solution for separating floors in refurbishment projects constructed using timber joists.

This fully tested system treats both the floor and ceiling, bringing together Hush-Panel 28 floating floor panels, Hush Seal 20 and Hush-Slab 100 sound absorbers fitted to Hush-Bar resilient bars.

HD1014 is a system which can upgrade the acoustic performance of traditionally constructed timber joists floors/ceilings with relative ease.

Tested as a complete system, HD1014 provides assured performance and is fully compliant with the Building Regulations relating to sound insulation - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland). It also provides 1 hour fire resistance.

How HD1014 is formed:

• Hush-Panel 28, with all tongue and groove joints glued using Hush-Bond, is laid over 18/ 22 mm T&G chipboard/plywood or the existing floorboards.
• The perimeters of the Hush-Panel 28 sound insulating boards are sealed using Hush-Seal 20.
• Hush-Slab 100 is then fitted between joists with Hush-Bars screw fixed to the underside of joists at 600 mm centres.
• Two layers of 15 mm Soundbloc plasterboard are then installed to the underside of the Hush-Bars, and all perimeters are sealed prior to skimming.
