Challenge
Contractors
Guaranteed Asphalt (GA) faced a unique conundrum regarding the
insulation of the roof of the O2 Arena, the centre piece
on the site of the former Millennium Dome and the first
purpose-built music venue in London since The Royal Albert Hall in
1871.
As the area required superior acoustic properties, a rock mineral
wool product was the obvious solution, however the split level roof
form of the construction meant that loose mineral wool fibres were
visible in the surrounding airspace. This is where Knauf
Insulation’s technical expertise became invaluable! Knauf
Insulation was able to specify a bespoke white-tissuefaced Krimpact
product which entrapped the loose fibres.
Solution
Knauf Insulation
supplied over 100 tonnes of their Rocksilk Krimpact Flat Roof Slab
Extra at 150mm (2x75mm), a consistent, high density rock slab with
superior impact and compression resistance. This material is
designed to offer not only the acoustic performance required by
such a venue, but also good thermal resistance and an excellent
fire rating classification (Euroclass A1 non-combustible, the
highest level possible). The white-tissue-faced product was
suitable to be exposed to the elements, and later sprayed with a
grey solar reflective paint to seal the surface and enable the
product to camouflage into its environment.
To make the project even more complicated, the cranes used in the
production did not fit under the existing structure of the Dome
which meant that the roof had to be constructed at ground level and
lifted into its final position. This was no problem for Knauf
Insulation thanks to its innovative Supakube delivery system, which
meant the product could be delivered to the correct area of the
project with minimum effort. Supakube uses advanced compression
technology and strong packaging materials, which ensures the
product is not only easy to store but can be delivered more
efficiently saving time and reducing carbon emissions from delivery
vehicles as more product can be loaded onto each lorry.
