Timber in joinery
Joinery is the non-structural use of wood and includes windows, doors, cladding boards, skirting boards, door linings, staircases and architraves. It also includes decking components such as decking boards, handrails and banisters, as well as less common items such as timber fins for solar shading. Joinery is known as ‘internal’ for applications inside a building and ‘external’ when situated outdoors.
