HD1019 Advanced System 2003: Acoustic floor system for timber floor refurbishment

The Hush HD1019 Acoustic system offers a fully tested, economical acoustic solution for separating floors and ceilings constructed using traditional timber joists, particularly in refurbishment projects.

The system utilises several of Hush Acoustics' high performing sound insulation products including Hush Panel 28 floating floor boards, Hush Seal 20 and Hush Slab 100 sound absorbers. It enables separating floors/ceilings to meet the minimum Building Regulations requirements - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland).

HD1019 is constructed in the following way:

• Hush Panel 28, with all T&G joints glued using Hush Bond, is laid over 19mm plasterboard plank and an 18mm chipboard deck, with all perimeters sealed using Hush Seal 20.
• Hush Slab 100 is fitted between joists with Hush Bar Plus System screw fixed to the underside of joists at 450mm centres.
• One layer of 19mm plasterboard plank and one layer of 12.5mm Gyproc Soundbloc plasterboard is secured to Hush Bar Plus System, with all perimeters sealed prior to skimming.
