About us

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 material wood, and cement extracted from Danish mineral resources.

We design, develop and manufacture the panels in Denmark – from local materials and under state-of-the-art and eco-friendly conditions.

Since 2022, Troldtekt has been part of the Kingspan Group, an Irish company which supplies high-quality building materials to the global construction industry.

About us

Cradle to Cradle roadmap

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.
