Étains La Flamme is Chateau Napoleon's signature French oxidation flaming process, an artisanal technique that enhances the natural beauty of premium French Oak and Black Walnut before the finishing stage. By carefully applying controlled heat, the wood's grain, texture, and character are brought to life, creating remarkable depth and individuality in every plank. Combined with traditional European craftsmanship and our exclusive finishing methods, this process produces the distinctive luxury hardwood flooring that defines every Chateau Napoleon collection.
