After successfully passing an SBI (Single Burning Item) Woodenha is now in possession of a Euroclass C Classification Report for BIME® preserved spruce cladding with tongue-and-groove jointed planks. The installation configuration for which this RC is valid:
- tongue-and-groove joint siding blades,
- mounting on wood frame classified at least D2-s2, d0 (no fireproofing required in most cases),
- with or without an air gap,
- against a support classified at least A2-s1, d0 with minimum density 525 kg/m3, minimum thickness 12 mm, with or without rain shield classified at least E.
This therefore offers new perspectives for 3rd and 4th family collective housing buildings, Public Access Buildings (ERP) or any other building with wooden cladding that requires an improved reaction to fire.
