External Oak Cladding
Oak weatherboarding is an attractive way to finish the exterior of both new and old buildings. Oak has been used for hundreds of years to protect houses from the elements. Of all the species available Oak is the most durable and therefore has the longest lifespan potential. It has only medium moisture movement in changing moisture levels. One feature of oak that must be considered is the high tannin content. During the first few years after the cladding has been attached, tannin will exude from the boards, resulting in streaks down the cladding and stains on masonry. Tannin also corrodes ferrous metal, so it is therefore important to use either stainless-steel or at least good galvanized fixings.
Oak cladding is typically available in square-edge, feather-edge and waney-edge boards in dimensions up to 300mm wide and lengths up to 4.0m.
Square-edge boards are simple 25mm sawn planks available in a range of widths. Square-edge boards can be overlapped to form horizontal cladding or used vertically.
Waney-edge cladding is a very traditional style of cladding created by overlapping boards sliced straight from the tree. Each board has one waney edge (with bark on) and one square edge.
Feather-edge boards are formed by sawing a rectangular section at an angle, resulting in two sections tapered across the width. Feather-edge boards are laid horizontally.
Oak cladding is supplied green (fresh sawn) with a sawn finish, cut from logs harvested in well-managed woodlands. Various widths and thicknesses are available by request.
