Pictured:  CEDAR CLADDING | Shiplap Profile | 133 mm x 18 mm Cedar Shiplap Cladding is a stylish, natural and strong alternative to traditional softwood and manufactured cladding systems. Shiplap boards are profiled to produce an overlap, which allows for a continuous timber cladding look with uninterrupted, clean lines. Cladding can be used in both vertical and horizontal alignment.
