Plywood is a type of engineered wood product that is made from thin layers of wood veneer, known as "plies," which are glued together. These plies are usually arranged with the grain of adjacent layers at right angles to each other, creating a strong and stable composite material.
Blockboard is a type of engineered wood product that is commonly used in construction and furniture making. It is made by sandwiching a core of softwood strips or strips of solid wood between two layers of plywood or veneer. The outer layers are typically made from thin sheets of wood veneer, and the core can be composed of strips of wood or particleboard.
A flush door is a type of interior door that is characterized by its smooth and flat surface. It is called a "flush" door because it is designed to be even or level with the door frame when it is closed, creating a seamless, flat appearance.
Shuttering plywood, also known as sheathing plywood or formwork plywood, is a type of engineered wood product specifically designed for use in concrete formwork and construction applications. It is used to create temporary structures, molds, or "shutters" into which concrete is poured and allowed to set.
