Birch is an abundant species found in the forests of the northern hemisphere being widespread across Canada and most of Northern Europe, in particular Finland, Latvia and countries bordering The Baltic. Birch species are relatively fast-growing and support a myriad of varied wildlife, and were managed as a sustainable forest resource, do not impinge on the natural biodiversity.

We buy no timber from Russia.

For quality, our sustainably sourced Birch Plywood is either FSC® or PEFC certification. We have a comprehensive “Chain of Custody” system in place to ensure transparency in sourcing timber products in line with the requirements of the European Union Timber Regulation (EUTR).
