The so-called Iceberg residential block in Aarhus is another remarkable design from celebrated Danish architects Cebra. It is also a showcase for the way in which bare basements and indoor car-parking areas can be transformed into pleasant and quieter environments by using sound-absorbent ceiling panels.
The building’s unique geometry is the result of a desire to maximise the views of every apartment over the water. Consequently, it has transformed the former container port of Aarhus into a vibrant and lively local community with a variety of different apartments for 7000 people and 12,000 workplaces. Since its completion, it has received international interest and recognition, including Archdaily’s Building of the Year Award, the MIPIM 2013 Award and, ARCHITIZER A+ Award 2013.
Like many other residential blocks, cars are parked under the building together with special niches around the staircases to accommodate cycles. In this large and rather ‘cold area’ with hard concrete surfaces, it was considered important to upgrade by reducing noise from cars and other resident activities. The architects’ solution was to install 2000sqm of Troldtekt panels in natural colours to improve the acoustics and create a pleasant texture and warmth.
Danish manufactured Troldtekt acoustic tiles are specified throughout the UK and Europe. Made with 100% natural wood fibres, their benefits are high sound absorption, high durability, natural breathability, low cost life cycle performance and sustainability. They are used to improve acoustics in many different projects, such as schools, swimming pools, commercial and public buildings. Available in various sizes and in three grades from ultrafine to coarse, they can be left painted or painted in virtually any RAL colour.
Troldtekt sustainability has also been recognised with certification at Silver level within the Cradle to Cradle concept. This international certification has been achieved because the panels do not contain hazardous substances and can be recycled.
