Soundproofing a multi-use residential and commercial building, Ellesmere Port

Hush Acoustics provided the acoustic floor and wall solutions for a development in Ellesmere Port, Cheshire involving the conversion of a former Woolworths store turned snooker hall, which was being transformed into a ground floor sports shop with nine first floor apartments above.

In addition to meeting the acoustic performance requirements, the client was also keen to ensure the design would meet the fire regulations required.

Following a site visit, the Hush HD1030 system was specified for the separating floors. This is compliant with UK Building Regulations Approved Document E and is suitable for refurbishment projects with timber structures that incorporate lath and plaster ceilings – all with the benefit of a 1-hour fire resistance at ceiling level.

We worked closely with EH Building Contractors to ensure the HD1030 acoustic floor system was installed to the required standard.

For the separating walls, Hush Twin Frame Metal Stud Party Walls were installed onto the plywood structural floor and isolated using 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.

The client had initially discussed keeping the original existing lay in grid ceiling within the shop, however, in order to achieve outstanding acoustic performance, the majority of the perforated metal panels from within the lay in grid ceiling had to be removed. Some of the original ceiling could be retained, however, with higher performing ceiling tiles used to replace it in other areas, maintaining the original features as per the client’s request.

Once completed, acoustic testing was carried out on site to determine the success of the acoustic design and installation. First of all, the twin metal stud wall was tested, which achieved an airborne performance of 56db (DnTw+Ctr). An airborne sound test was then conducted between the sports shop and one of the first floor apartments which showed a performance of 47 dB (DnTw+Ctr).

All of the acoustic performance goals were achieved without any significant ceiling treatment and our client was happy with the results.
