Statutory requirements

To limit or delay the spreading of fires via the wooden facade, the Royal Decree imposes various requirements with regard to the reaction to fire of wooden facade cladding in its end-use conditions (in other words, as present on site).

This means that when assessing the reaction to fire of the wooden facade cladding, one must take into account the potential influence of the underlying material layers and the way in which they are fastened.

What are the requirements?
