Sound insulation 'a key concern for Dublin Airport's Terminal 2'

Sound insulation has been described as a key concern in the construction of the roof for Dublin Airport's Terminal 2.

Writing for Building.co.uk, Stephen Kennett said acoustics was a primary specification, but thermal performance and ease of maintenance were also important.

The roof has eight separate layers, with a structural steel deck, an acoustic insulation layer and an acoustic liner tray for internal noise.

Above the steel deck is a 10mm thick cement particle board, which protects against external sound pressures, while 200mm of Rockwool insulation is used as a heating material.

'The Kalzip aluminium standing seam panels provide the weathering layer which is overclad with the Alucobond rainscreen,' he explained.

Architect with Pascall + Watson Paul Ruggles noted that the solution is clever because it wraps around the entire building, with a sound reduction of between 47 and 54 decibels.

Terminal 2 is expected to handle around 15 million passengers per year and cost around €395 million (£333 million) to build.
