In 2021, two major fire tests were carried out: "Assessment of fire-technical properties of wooden façade cladding - Fire testing of wooden cladding with different types of treatment" and "Fire in cavities behind royal-treated pine cladding". The fire tests were carried out by RISE Fire Research and show that Royal-impregnated cladding is not more flammable, or leads to increased spread, than other types of finished surface-treated cladding.
The good news is that with the help of the digital tool Branntrygg.no or a fire advisor, you can use Royal on most wooden buildings.
Feel free to contact us in connection with the use/training in Branntrygg, or ask your fire consultant to add class E to the surface cladding in connection with the preparation of a fire concept.
Branntrygg is free to use and takes a maximum of 15 minutes.
