Softwood

European Douglas

European Douglas is one of the strongest and most dimensionally stable softwood species native to Europe. Its heartwood falls into durability class 3, offering reliable outdoor performance, a warm reddish‑brown colour and a distinctly robust appearance. When left untreated, Douglas naturally weathers to an elegant blue‑grey tone — a process that can be slowed or prevented through staining or impregnation.

Thanks to its structural reliability, natural strength and visual appeal, European Douglas is a valued material for both exterior and interior applications.
