EPDs document the carbon footprint from Troldtekt acoustic panels
In August 2025, EPD Denmark published new environmental product declarations (EPDs) for Troldtekt's acoustic panels. One of the main things documented by the EPDs is the carbon footprint (Global Warming Potential) in all life cycle stages of the panels.
In just a few clicks, developers, consultants and installers can find the carbon footprint for different variants of Troldtekt acoustic panels. This is useful when preparing life cycle analyses (LCAs) for building projects.
The Troldtekt EPDs have been drawn up in accordance with the EN 15804+A2 standard and include the stages:
See the total carbon footprint
One crucial piece of data in the EPDs is the carbon footprint per square metre of a Troldtekt acoustic panel, which is known as the Global Warming Potential (GWP). You can see the total carbon footprint for four different Troldtekt acoustic panel variants in the graphs below.
Important to know:
> The graphs show the carbon footprint of four Troldtekt acoustic panel variants. Each of the four has its own EPD.
> The footprint is calculated for each stage. For some stages, the footprint will be negative, while for others it will be positive. The total is calculated as a number. Read more about each stage in our guide to using EPDs.
> Please note that the four EPDs apply to unpainted Troldtekt panels. If you use painted panels, you need to add the footprint from the paint to the specified figures. The number you need to add can be found in the EPD. The paint's footprint has been taken from our paint supplier's EPD.
> The four EPDs apply to all panels with a thickness of 25 mm. If you use panels with a thickness of 15 mm or 35 mm, you need to convert using the factor specified in the EPD.
Reduction from cement
Compared to Troldtekt's previous EPDs from 2021, the carbon footprint has been reduced:
> The carbon footprint is now 12 per cent lower for Troldtekt in natural wood, which is based on white cement
> The carbon footprint is 20 per cent lower for Troldtekt based on the FUTURECEM™ cement type.
Troldtekt acoustic panels consist of wood and cement and, at the Troldtekt factory in Troldhede, 98.3 per cent of energy used in production originates from renewable sources. In 2021, this figure was already 97.8 per cent.
The carbon reduction in the 2021-2025 period has primarily taken place in the production of cement, which Troldtekt purchases from external parties. There have been reductions for both the white cement included in the panels available in natural wood and for FUTURECEM, which is included in all other panels.
Three end-of-life scenarios
In addition to the lower carbon footprint, the EPDs have been updated in a number of areas since the 2021 versions. For example, construction waste has been included in stage A5 and the conditions for product transport from Troldtekt's factory to the building site have been adjusted in stage A4. The average transport distance has increased.
It is now also possible to select carbon figures for three different end-of-life scenarios when the panels reach the end-of-life stage:
> Incineration (main scenario in Denmark, where Troldtekt's production takes place)
> Landfill
> Recycling of crushed panels in the biological cycle.
Landfill results in a higher carbon footprint than the main scenario, while recycling results in a lower footprint.
Independent verifiers
The EPDs have been published by EPD Denmark. The life cycle analyses themselves were prepared by Stefan E. Danielsson, who is an independent verifier affiliated with EPD Denmark. The EPDs have been third-party verified by one of the other independent verifiers affiliated with EPD Denmark.
