Beetham West Tower
The Challenge
Liverpool’s tallest building, Beetham West Tower, is a 40-storey mixed-use development, incorporating commercial office spaces, residential apartments and Sky Bar. Located on the top floor, Sky Bar is a luxury restaurant and bar providing excellent views of the city.
At specification stage it was discovered that with no acoustic treatment, the impact sound generated in Sky Bar would be heard in the offices and apartments below. Low frequency noise that would be produced from the extraction system in the kitchen area also caused particular concern. As such, an acoustic solution was required to address the potential impact energy and maintain the premium status of the development by preventing disturbance to residents.
The Solution
After flooring contractors, Elite Screed, consulted CMS Acoustics, Regupol 7210C, a recycled rubber granulate underscreed acoustic system, was identified as the most cost effective impact sound solution. Regupol 7210C delivers superior sound insulation of 46dB and 49dB for impact and airborne sound respectively. The material, available exclusively through CMS Acoustics in the UK, undergoes minimal creep and will retain these high performance levels for the lifetime of the installation, even under high loads.
Supplied in standard sheets sizes of 2,300mm x 1,150mm, Regupol 7210C has a guaranteed material thickness of 5mm. Compatible with all types of screed, Regupol 7210C is ideal for use in new build developments where pre-completion testing is preferred to Robust Detail.
Regupol 7210C was used to cover the entire 375m2 flooring area of Sky Bar. Quick and easy to install, the material does not require separate perimeter strips to achieve complete isolation as the sheets are simply turned up at the edges and the screed laid directly on top.
Results
The specification of Regupol 7210C at Sky Bar effectively prevented the impact sound generated from the bar and kitchen areas from travelling into the offices and apartments below.
Matthew Delargy, assistant quantity surveyor, Elite Screed, comments: “As a premium development it was imperative that noise from the restaurant could not travel into the surrounding apartments. We’d worked with Regupol 7210C previously, so we knew it was quick and simple to lay, and would deliver a cost effective and high performing underscreed solution.”
