Troldtekt is certified according to the best indoor climate categories by Danish Indoor Climate Labelling (Dansk Indeklima Mærkning).

The indoor climate is a combination of air, smell, sound, light, humidity, static electricity, design and colour.

Danish Indoor Climate Labelling (DIM) is a voluntary labelling scheme for building materials and their impact on the indoor climate. The indoor climate label is common to Norway and Denmark, and is recognised worldwide. Read more about Danish Indoor Climate Labelling (Dansk Indeklima Mærkning (DIM)).

For the indoor climate label to be granted, the product must meet certain product use requirements, while the product’s impact on the indoor air quality is also looked at. One factor is the content of chemical substances in the product, another is which substances are released into the indoor environment. A product certified and labelled under the indoor climate scheme has been subject to extensive testing, and comes with documentation regarding the release of chemical substances into the air. Ceiling products are also tested for the release of fibres and particles.

Testing for degassing
All products are classified with a time value in days – the time value relevant for indoor climate. The time value is determined on the basis of the time that passes before the degassing ‘subsides’. The time value is determined through chemical analysis and sensory (smell) evaluation.

Troldtekt is classified with the time value 10 days, which is the best category.

Testing for particle release
In connection with indoor climate certification, ceiling products are also classified for particle release, determined through sedimentable dust consisting of particles and fibres during the early use of the product.

The release of particles and fibres from Troldtekt is classified as low, which is the best category.
