Woodsafe is a refinement of wood's natural properties against the effects of fire. The type of wood that is treated is in symbiosis with fire impregnation that achieves the relevant fire class, for example SP-Fire 105 and Euro class B-s1,d0.
The fire impregnation itself is not film-forming in comparison to fire protection paint, which only creates a coating on the current painted surface. This is important to understand because coating with fire retardant paint or varnish is only applied to the surface and does not improve the wood's own properties in terms of resisting fire. In the comparison between Woodsafe fire impregnation and applied fire protection paint, the impregnation always provides 6 sides of in-depth fire protection, while the fire protection paint only provides a surface layer on the currently painted surface, which means that if wooden panels are installed sparsely, the edges must also be painted, and if the panel is installed sparsely with an accessible back, the back must also be treated. You always get this in the bargain with Woodsafe fire impregnation.
