Troldtekt®-acoustic panels, Tivoli Congress Center

01 product description

Product description

The Tivoli Hotel and Congress Center was designed by Kim Utzon Arkitekter. Together with a central green pedestrian street, the Center’s architecture is inspired by the natural conditions of the site – the cliffs eroded by the sea and a pleasant adjunct to the Danish landscape not exactly abundant with mountains. The Tivoli hotel itself rises 13 floors and is topped with a roof terrace commanding spectacular views of the city.

Troldekt acoustic panels have been used in most rooms including the 1700sqm lobby which is designed for a variety of purposes. Together with the Oland stone floor, the pale shades of the ceiling inject the only colours into this white painted space which is flooded with daylight . It also conceals all the services, such as power and sprinkler systems.
As architect Kim Utzon says, ‘The acoustics in the foyer are well-balanced because the panels are set between the ribs of the structural concrete elements. It’s a tried and tested solution which works beautifully and never lets us down – even when noise levels are high.’

Like a large rock formation, the huge 2500 seat congress hall lies halfway between the two existing hotels. Constructed on two levels, it has a black painted Troldekt Acoustics Plus ceiling set within very large black triangular lattice girders which dominate with their span of almost 40 metres. The walls have birch veneer panels with slits to supplement the ceiling’s acoustic absorption.

Troldtekt panels are made from 100% natural materials; wood from Danish forests and cement produced by Aalborg Portland, Denmark. The structure of Troldtekt panels provides a basis for excellent sound absorption, and using Troldtekt ceilings will, therefore, reduce noise and provide optimal room acoustics. Troldtekt is available in a high number of combinations that vary according to surface structure, edge, installation system, colour, dimension and thickness.
