OVERVIEW
Chestnut is a species of wood that exudes natural beauty and a golden colour. Chestnut is suited to a wide range of timber cladding projects. It is typically the preferred species for projects that require a hard wearing and stable wood as it isn’t as vulnerable to knocks, scrapes and scratches as other materials.
