Douglas fir wall cladding panel IGNI-B

for indoor usefor facadefor outdoor use

Overview
IGNI-B is PIVETEAUBOIS's proprietary technology for in‑mass fire protection of wood. By vacuum-pressure autoclave impregnation followed by gentle drying, planed boards achieve a reaction-to-fire classification Euroclass B-s1,d0, maintained over the product service life for both interior and exterior use. Primary application: exterior cladding in Douglas without sapwood. The fire retardant used is Burnblock®. Industrial process performed under CE marking. No finishing treatment or specific maintenance is required to retain the Euroclass B performance.
