Sustainability and sourcing
Kankrao grows and is planted in Thailand. Using timber with a traceable local source keeps transport short and helps protect trees in natural forest.
WisutWood uses legal timber, can issue sawn-timber control documents, and kiln-dries to 12% moisture content or less, so the woodwork lasts and does not have to be torn out and replaced.
