Acoustic panels with a negative carbon footprint
The new Troldtekt® panels absorb more CO2 than they emit during production.
Troldtekt A/S is now launching acoustic panels made using the patented cement type FUTURECEM™ from Aalborg Portland.
The mixing of the wood in the well-known acoustic panels with FUTURECEM rather than traditional cement represents a major milestone in Troldtekt’s work with sustainability. FUTURECEM is a patented cement product which synergises calcined clay with lime filler. In this way, much of the fired clinker in Aalborg Portland’s cement production can be replaced.
The CO2 embedded in the wood exceeds what is emitted during the production of FUTURECEM.
During use, the cement layer in a Troldtekt panel gradually absorbs CO2 via the chemical process of carbonisation, which further reduces the negative carbon footprint.
“It is the cement that gives Troldtekt acoustic panels their strength, durability and fire-protective properties without the use of harmful chemicals. The benefits are difficult to achieve with binders other than cement. Therefore, we’re very excited that Aalborg Portland has developed FUTURECEM, as it enables us to be both climate-friendly while preserving all the well-known benefits of our acoustic panels,” says Peer Leth.
Both the classic panels and the solutions in the Troldtekt design series will be available based on FUTURECEM.
Both the classic panels and the solutions in the Troldtekt design series will be available based on FUTURECEM. “Our ambition is for the Troldtekt panels which are currently made with white cement to be manufactured using FUTURECEM in the future. The potential carbon savings are even greater when replacing the white cement, which emits more CO2 during production. We are confident, but further product development is still required,” says Peer Leth.
