HD1015 Hush Batten 55 acoustic insulation system for floors and ceilings

The Hush Acoustics HD1015 Hush Batten system provides a highly effective solution for improving sound insulation in separating floors and ceilings. Utilising Hush Acoustics' own high quality insulation materials, the system has been fully tested to achieve performance requirements in excess of the Building Regulations minimum standards.

Perfect for refurbishment and conversion projects falling under Material Change of Use, HD1015 brings together the Hush-Felt 10 Resilient Layer, Hush-Seal 20 and Hush-Slab 100 sound absorbers in one easy to specify and use system. The system can be applied to floors with a beam and block structure with a minimum density of 260 kg/m2, with a design that creates service voids above and below the floor structure to deliver its excellent acoustic performance.

The system complies with the requirements of the Building Regulations relating to passage of sound within buildings - Approved Document E (England & Wales), Part G (Northern Ireland) and Section 5 (Scotland).

The HD1015 Hush Batten 55 system comprises:

• Hush Battens which are loose laid at required centres over a layer of Hush Felt 10 Resilient Layer.
• T&G chipboard/plywood, to suit batten centres and loadings, is laid over the Hush Battens using Hush Bond and screw fixings, with all perimeters sealed using the Hush Seal 20 perimeter strip.
• Hush MF system is installed to the underside of the beam and block structure. The Hush MF ceiling creates a 150mm void from the underside of the beams to the back of the plasterboard lining.
• Hush Slab 100 Sound Absorber is installed tightly together within the ceiling void.
• Two layers of plasterboard are attached to the underside of the Hush MF ceiling. The plasterboard lining should be 19mm Plasterboard Plank and 12.5mm Soundbloc.
