About Troldtekt acoustic panels

Classic acoustic panels for all types of building projects

Troldtekt acoustic is our classic acoustic product, which is a popular choice in offices, schools, institutions, sports centres, cultural venues, private homes and many other types of buildings.

The panel is made of cement-bonded wood wool, a combination of certified wood (FSC® C115450 or PEFC/09-31-030) and cement. The surface can be painted, but many choose to leave the panel unpainted for a natural look.

As wood is one of the two raw materials, colour variations may occur, especially in variants such as natural wood and FUTURECEM™. For a uniform result, we recommend mixing up the panels when mounting.



Ensures optimum acoustics

Troldtekt acoustic panels can be mounted as ceiling and wall cladding. As an acoustic ceiling, the panels are installed directly on battens or in a suspended profile system, and often with a mineral wool backing for optimum sound absorption.

In spaces where the need for good acoustics is particularly high, such as in institutions and swimming pools, installing Troldtekt panels on both the ceilings and sections of the walls is an ideal solution.

Benefits of choosing Troldtekt® acoustic

We combine design and enhanced acoustics with a healthy indoor climate.

Outstanding acoustics
Outstanding acoustics
Good acoustics are a prerequisite for a good indoor climate. If the acoustics are bad, sound is experienced as noise, and you'll find it difficult to hear what's being said.
Classic design
Classic design
Troldtekt acoustic is a classic acoustic panel that can be incorporated into most designs while creating a uniform surface that provides visual calm and elegance.
Multiple installation options
Multiple installation options
Troldtekt acoustic is ideal for spaces with a special need for good acoustics, such as classrooms, institutions and swimming pools. Ideally, the classic acoustic panels should be mounted on both the ceilings and parts of the walls to ensure even higher sound absorption.
Sustainability
Sustainability
Throughout the product cycle, Troldtekt places emphasis not only on minimizing the environmental impact, but on optimizing resource consumption and processes.
Effective fire performance
Effective fire performance
Troldtekt panels are made from certified wood, and cement extracted mainly from Danish mineral resources. Wood is an organic and flammable material, but every single wood fibre in a Troldtekt panel is encapsulated and protected by non-flammable cement. Troldtekt panels therefore have low flammability and only emit low heat during a fire, and almost no smoke.
Improved indoor climate
Improved indoor climate
Troldtekt ensures good acoustics, which are an important part of a healthy indoor climate. At the same time, Troldtekt is documented as being free of harmful substances that can contaminate the indoor climate. In addition, the acoustic panels can both absorb and emit moisture, which can make the indoor climate feel more comfortable.
