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. Examples of waney edge cladding can be seen on buildings dating back many hundreds of years, often painted in traditional black bitumen paint.

Today the most common species used for waney-edge cladding are British larch and elm. Oak is occasionally used but the tendency of the sap wood to rot can cause problems. This style of cladding is ideal for projects such as barn conversions and listed buildings.

The boards are laid to show the waney edge, with an overlap of 40 – 50mm. It is important to follow fixing advice, particularly when using green (wet) timber.
