Troldtekt A/S becomes part of Kingspan Group: Common vision of growth and sustainability journey

Troldtekt A/S, the Danish producer of acoustic panels made from wood and cement, becomes a part of the Irish Kingspan Group. Thus, Troldtekt joins a global group that shares the vision of a sustainable construction industry. The new ownership will prepare the company for continued international growth – with a significant production expansion in Denmark.


After thorough dialogue with both manufacturing companies and private equity funds, Troldtekt A/S has found a new owner. On Thursday the 10th of February 2022, the contract with the listed construction group Kingspan Group was signed. Now remains the formal approvals from authorities, which are expected to fall into place within the next couple of months.

– Right from the beginning, we have had a good dialogue with Kingspan, and we have only been further reassured, that there is a strategic match between our companies. Our ambition was to find the right owner, who has the insight and values to develop Troldtekt – also as a manufacturing company. And at the same time an owner, who shares Troldtekt’s ambitions on growth through a focus on sustainability. Both aspects are fully fulfilled with Kingspan, says Kurt Bering Sørensen, Chairman of the Board at Troldtekt A/S.

Troldtekt continues under the same name and with the same well-known brand, which has been on the market since 1935. Also, the production remains in Denmark, where Troldtekt now must double the capacity with an extra factory to the existing factory in Troldhede in Western Jutland.

Troldtekt has a great potential
– Troldtekt is an innovative company with a wide range of acoustic solutions, which will be a strategically strong supplement to our product portfolio in the Kingspan Group. Troldtekt is also a well-run company, which has been able to continuously innovate, and which sets the bar impressively high in the field of circular economy. The potential for international growth is great. We look forward to realizing that potential together with Troldtekt’s skilled employees, he says.

Great ambitions in the circular economy
For more than a decade, Troldtekt has worked specifically and strategically with the sustainable design concept Cradle to Cradle.

Of the energy used in production, 97.8 per cent comes from renewable sources, and the cement-bonded wood wool waste is recycled as a raw material in new cement at Aalborg Portland.

In March 2022, Troldtekt will be launching acoustic panels based on the cement type FUTURECEM™. The new panels have a significantly reduced carbon footprint compared to Troldtekt based on traditional cement.

– Troldtekt’s business strategy is based on a sustainability focus and Cradle to Cradle-thinking. This is the central reason to the growth in recent years. It has been important to us to find an owner with solid ambitions within the climate field, and we are confident Kingspan will build on the already sound foundation, says Kurt Bering Sørensen.
