Wooden fire-retardant cladding Euroclass B / C: the BIME®1 process


vignette-bardage-m2-bime-plaquette

In some cases a Euroclass C or B facade may be required, especially for the Public Assembly Buildings when the "C+D rule" shall not apply, or for some kinds of Appartment Buildings (4 floors and over mainly).

This can be reached for wood treated following Woodenha's BIME®1 process:  it consists of a fire-retardant treatment in autoclave followed by Kiln Drying and coating with the BIME®F1 wood stain. Depending on the wall system mount, the wood classification can then reach Euroclass C and sometimes Euroclass B. Woodenha now holds numerous Euroclasse Classification Reports and Certificates for Durability Outdoor.

 

The BIME®1 (french accronym for Bois Ignifugé dans la Masse pour Extérieur) Process

 

Test of durability have been made on BIME®1 Douglas Fir and BIME®1 Larch. Both have succeeded Woodenha holds a Certificate of Durability for those two species. Others species are being tested such as thermo-treated wood, Red Cedar etc...

The Euroclass test (Single Burning Item / SBI) has been made first on continuous building systems (groove-and-tongue type of cladding) going from 19mm to 43mm of thickness. With years, Woodenha has certified other systems such as lattice-work cladding (Douglas Fir, Larch, Western Red Cedar and High-Temperature-Treated Wood), solid wood pannels (Douglas Fir and Larch).

Any other combination of species/mounting system for which no report is available should be SBI-tested first. Woodenha can run such tests on demand.
