The 8'x4' 18mm Medium Density Fibreboard (MDF) is a versatile and popular choice for a wide range of indoor construction and woodworking projects. This MDF board is composed of wood fibres bonded together with resin under high pressure and heat, resulting in a strong and uniform material. With dimensions of 8'x4', it provides ample coverage for various applications such as cabinetry, shelving, furniture, and interior panelling. The 18mm thickness strikes a balance between strength and flexibility, making it suitable for both structural and decorative purposes.
