The Mulberry product line is made by compressing mulberry branches that are sourced first as a by-product from silk production, and then as a by-product from the filtration industry. Silk worms eat the leaves of the mulberry tree to make silk. The branches must be pruned so the leaves can regenerate the next growing season to make more silk. The trimmed branches are collected, sorted, and then they undergo a process to remove the bark, which are then used in industrial water filtration applications. The inside wood fiber from the mulberry branch is what is used for the creation of compressed mulberry block material.

Mulberry Product Formats

The Mulberry is available in both a “solid” and “engineered” format. As described on the Songwood Product section, the “solid” indicates that the entire thickness of the material is made from the same wood strands, in a single lamination. Despite being called “solid” it is more stable than other solid woods because it is, in effect, made from small wood strands compressed to a solid mass. The true “engineered” flooring format takes the solid block material, cuts it into a “wear layer” and then mounts it onto a different core material. The core/base material is typically sourced as a “multi-ply” of poplar, birch, or eucalyptus, but can also be made in a laminate form using High Density Fiberboard (HDF). These engineered core/base structures can be sourced as either “FSC” (enabling the engineered to carry 100% FSC designation like the “solid”), or on a traditional core giving it mixed source designation.
