What is particleboard?

Particleboard is made from recycled wood and sawmill waste – so wood pieces with the wrong shade, woodchips and sawdust become a valuable resource instead of being discarded. We use boards for things like bookcases, bed frames, sofas and kitchen frames. To protect from wear and moisture, we apply varnish, veneer or foil that adds to the furniture's look. The day your sofa or bed needs replacing, the material in the particleboard can be recycled into something entirely new.
