Being both durable and tough, oak has long been a favourite choice for hardwood cladding. Oak cladding boards are selected for limited knot content and are supplied as random lengths or as finger-jointed boards.

Instability and tannin
Oak cladding from Vastern Timber
The colour of oak is quite variable, ranging between pale yellow and light brown. The variation is more pronounced on the finger-jointed boards and zigzag joints are noticeable. Oak cladding boards will contain small pin knots and tight knots up to approximately 30mm.
Finger-jointed boards will include noticeable zigzag joints at intervals of 400 to 900mm.
As the boards naturally weather the colour will change to a silver-grey. On shaded elevations or in areas of higher pollution the oak may weather to more of a black colouring. In semi-shaded areas such as under eaves the exuding tannin may leave unsightly stains.
Desired service life
Occasionally wet 60 yrs. Frequently wet 30 yrs.
Resistance to impact
Dry oak is hard and will require pre-drilling.

Oak contains tannic acid, which will corrode ferrous metals. All fixings used in conjunction with oak must be stainless steel. Tannic acid could also leave unsightly brown stains in the surface of the cladding and will stain any porous materials below the cladding. The reactivity of tannin makes oak cladding unsuitable for polluted areas and shaded areas.
How to fix
Pre-drill and hand nail with stainless steel nails through the face. Do not attempt to secret nail through the tongue. We do not recommend first or second fix nail guns.
** Be sure to leave an expansion gap between boards**
