Clapboard is a wooden siding material comprising narrow horizontal planks overlapped to create a weatherproof exterior covering for buildings. Each plank overlaps the one below, allowing water to shed downwards. The boards are typically tapered in profile, with the thicker edge at the bottom. Traditionally made from cedar or pine, modern clapboard may also be manufactured from composite or vinyl materials. The style originated in New England and remains common in North American architecture. In the UK, clapboard is less common but appears in period buildings and heritage restoration projects.
