This iconic Grade II* Listed building began construction in 1911, although World War 1 and 2 halted completion until 1958. For 64 years, County Hall served as the home of the British Government. Under new ownership, County Hall houses the London Aquarium, London Dungeon attractions as well as the Premier Inn and Marriott Hotels.
In 2016, London venue company ‘etc.venues’ announced plans to open a conference and event space in County Hall. It features 20 multi-purpose interconnecting spaces including two river fronting suites for groups of up to 900. The nature of the business and the noisy external environment required a demanding level of sound attenuation and compliance with BREEAM requiring special measures to reduce heat loss.
Synergy Architects turned to Selectaglaze, the leading provider of secondary glazing, to install thermal and acoustic efficient secondary glazing. As there were no rising ducts of a satisfactory size, air needed to be supplied and extracted through the existing windows; therefore secondary glazing was only required to the lower part of these windows.
Selectaglaze installed a total of 148 secondary glazing units which were a combination of horizontal sliders and lift-out units. Those units exceeding 1600mm high were fit with a 6mm toughened low-E glass. A minimum glass to glass cavity of 150mm allowed for optimal noise reduction. All aluminium profiles and timber grounds were powder coated in a matt grey finish.
The secondary glazing has enhanced business prospects at ‘etc.venues’, with conference rooms, event suites and bars now providing an ambient and warm environment to suit any event requirement.
Selectaglaze will be exhibiting at the UK Security Expo, at London Olympia on the 29th and 30th November 2017. Located on stand L66, Selectaglaze Technical Advisors will be happy to answer any secondary glazing related questions.
