Hush Acoustics were called to a former Woolworths Store turned Snooker Hall in Ellesmere Port, Cheshire, which was being converted into a ground floor sports shop with nine 1st floor apartments above. The brief given was to address both the acoustics within the building whilst also meeting the fire regulations required.
The HD1030 system was specified to meet the requirements. The HD1030: Hush System LP is compliant with UK Building Regulations Approved Document E and is suitable for refurbishment projects with timber structures that incorporate lath and plaster ceilings. It also has 1-hour fire resistance at ceiling level.
To install the HU1030 system, the floor was insulated between the joists with Hush Slab 100, rested on Hush Mesh Fire Wire, before a new structural deck of plywood on timber packers were installed, creating a level base to hold the acoustic floor system.
19mm Plasterboard Plank was then laid over and sealed using our Hush Acoustic Sealant. Hush Panel 28 was then fitted as the overlay acoustic flooring treatment, finished over the plank in the opposite direction, ensuring all joints were staggered. The perimeters of the Hush Panel were then sealed using Hush Seal 20 and all joints glued with Hush Bond Panel Adhesive.
Hush Twin Frame Metal Stud Party Walls were installed onto the plywood structural floor and isolated using our Heavy-Duty Isolation Tape. The stud walls were insulated using the Hush Slab 100 Sound Absorber, ensuring the cavity between the two stud frames were kept clear.
Two 15mm Soundbloc Plasterboards were used either side of the wall, ensuring both the acoustic and fire performance requirements were achieved.
Once completed, Hush Acoustics tested their twin metal stud wall which achieved an airborne performance of 56db (DnTw+Ctr). An airborne sound test was then carried out between the sports shop and one of the 1st floor apartments which achieved a performance of 47 dB (DnTw+Ctr).
