Understand the benefits of Knauf Danoline products:


The properties of Knauf Danoline products will not diminish for at least 50 years. They retain the same strength, the same acoustic characteristics and the same fire resistance. All products can be repainted again and again without any loss of acoustic or other technical properties.

And at the end of their lifespan, our products are wholly recyclable.


Knauf Danoline products are painted with water-based paint. This ensures maximum recyclability, maintains the gypsum’s natural humidity regulating properties and keeps the gypsum core free from harmful additives.

In addition, the acoustic cellulose felt on the back of Knauf Danoline’s perforated gypsum boards not only increases their flexibility, it is also biodegradable.

Similarly, the cardboard in Kanuf Danoline plasterboard products is produced from 100% recycled sources. The cardboard and paper foils are also separated from the gypsum at the recycling plant, enabling a greater proportion of waste to be recycled.
