Troldtekt A/S

At Troldtekt A/S, we believe that acoustic comfort and a healthy indoor climate are key elements of high-quality buildings.

Since 1935, we have manufactured Troldtekt acoustic panels from the natural materials wood and cement. We design, develop and manufacture the panels in Denmark – from local materials and under state-of-the-art and eco-friendly conditions.

Troldtekt manufacturing video

This video gives you a tour in our production facility and shows you the production process - all the way from raw materials to the final product.

Additionally, the video also introduces you to our sustainable solutions and their main characteristics.



At Troldtekt we have made the Cradle to Cradle concept a part of our business strategy. We have entered into a long-term cooperation with Cradle to Cradle Denmark, who will help us implement the new strategy. Together we have developed a roadmap for how we, based on the five main categories of Cradle to Cradle certification, can ensure quality in our Cradle to Cradle work. We have made an ambitious plan with a number of value-creating initiatives towards 2022. Our roadmap is not an answer book, but a plan which will be continuously amended and updated, as we identify new opportunities. For example, we have already surpassed our original goal of getting 50% electricity from wind power by 2015, since we already as from July 2013 receive 100% wind power from DONG Energy.

Troldtekt Award winner 2012

Troldtekt® Award

In 2010, Troldtekt could celebrate its 75th anniversary with an introduction to the Troldtekt Award. The concept competition was for Danish students of architecture and the goal of the competition was to find new creative uses for Troldtekt.

In 2012, we opened the competition for all international students of design and architecture. The competition for the Troldtekt Award involved incorporating Troldtekt into an architectural project in a completely new and original way. The only condition was that Troldtekt was incorporated in a key and innovative way. In other words, participants could choose to impose colours, shapes, their imagination or something completely different on the Troldtekt products.

In 2014, Troldtekt also invited all architectural and design students from all over the world to participate in the Troldtekt Award 2014 competition. The most creative idea for using our acoustic panels was awarded a cash prize of EUR 5,000.
