Air Dried Oak Shiplap External Cladding

Our Air Dried Oak Shiplap External Cladding is shiplap cladding in European oak, for external use.

About European oak

Air dried (seasoned) European oak: the boards are dried outside for approximately 6 months, to between 16% and 25% moisture content. More stable and less prone to shrinkage than fresh sawn oak.

Characterful boards that may show a small amount of sap on the underside, sound knots without limitation and occasional historic insect damage.

Supplied untreated.

Left alone it weathers to silver grey.

Profile and fitting

Usually fitted horizontally. The shiplap profile gives clean shadow lines along the length of the building.

Grades and options

• First Grade: mostly clear of knots, with some knots up to 5 mm allowed and a small amount of sap on the underside only.
• Character Grade: sound knots without limitation, sap and occasional historic insect damage.
• End matching (tongue and groove on the board ends) lets you place joints where they fall rather than on a batten, which speeds up fitting and reduces wastage.

Good to know

• Use stainless steel fixings only. This is essential for oak: its tannin reacts with ordinary steel fixings and causes dark staining.
• Natural timber varies: expect some differences in colour and grain from board to board and from the photos.
• Boards left exposed to changing weather before fitting are likely to cup, warp and split. We suggest fitting between October and April where possible, within 7–14 days of delivery.
• Sizes are nominal and can vary slightly with moisture content.
• Not sure? Order up to two cladding samples first.
