Troldtekt sound absorbing acoustic panels are made using nature's own materials - wood (wood wool) and cement

Natural raw materials

Troldtekt is cement-bonded wood wool panels made using certified wood (wood wool), a 100% natural material, and cement extracted from Danish mineral resources.

The recipe for Troldtekt acoustic panels is as simple as it is viable, and has been followed since 1935.

By mixing wood and cement, we create cement-bonded wood wool, combining the strength of cement with the natural properties of wood. The result is a healthy material with a number of inherent natural benefits.

Structures & colours

The surface structure of Troldtekt acoustic panels is determined by the width of the wood shavings (wood wool).

Troldtekt products are available in four different structures; extreme fine (0.5 mm), ultrafine (1 mm), fine (1.5 mm) and coarse (3 mm).

Troldtekt is available as untreated and completely natural panels, and as painted panels. The acoustic panels consist of wood wool mixed with either white or grey cement, from these mixtures we produce the two basis variants: natural wood and natural grey.

Painted Troldtekt panels are available in any RAL/NCS colour code.

Wood wool acoustic panels from Troldtekt are available in several standard colours and four structures from extreme fine to coarse

Storage and acclimatisation of Troldtekt wood wool panels

Storage & acclimatisation

Troldtekt is a natural material consisting of about 50% wood, and the panels will therefore ‘work’ in order to achieve the same temperature and moisture level as their surroundings.

You should therefore not begin installing Troldtekt panels before the building has been completed and the heating has been turned on.


To ensure that you achieve the best possible result, it is important that you store Troldtekt panels correctly and that you follow our installation instructions when installing the Troldtekt ceiling.
