OVERVIEW
Hush Acoustics provided a range of acoustic products for the construction of Warren Court, a new development of 9x luxury two bedroom apartments.
Working with Marlowe Building Contractors, we provided advice and materials for the apartments’ soundproofing to give acoustic performance better than New Build standard.
The Standard Assessment Procedure (SAP) energy ratings had already been calculated and passed before Hush were involved with the acoustic design. The building’s structure consisted of lightweight masonry walls and a timber joist floor structure, which could not be changed due to SAP compliance.
As a result, Hush was tasked with developing a comprehensive design to ensure compliance to Approved Document E of the Building Regulations with this form of construction detail. The biggest issue was the continuous lightweight block walls that may be thermally very efficient, but present major difficulties acoustically.
To go over and above the new build standard, it was necessary for all blockwork and timber floor joists to be isolated on Hush Resilient Seating. Ceilings were also isolated by using Hush Suspended Ceilings in the main and an Enhanced Clip and Channel System was used where the floor/ceiling heights were at a premium. Hush Panel 28 was provided throughout as the floating acoustic flooring system.
We carried out pre-completion sound tests which achieved results well in excess of the new build standard. Airborne sound test results ranged from 49 dB (DnTw+Ctr) to 61 dB (DnTw+Ctr) and impact achieved 46 dB (LnTw), 16 dB better than the required new build standard.
