Cladding is a concept that describes components that are added to a building's primary structure to construct non-structural exterior surfaces. In comparison, in buildings where the exterior surfaces are created by structural elements like masonry walls or applied surfaces like render, the external surfaces are formed by structural elements like masonry walls or applied surfaces like render.
HPL panels are a form of cladding made by layering sheets of wood or paper fiber with a resin and bonding them together under heat and pressure. They are available in a variety of colors and finishes, and they can contain additional chemicals to provide fire retardant properties. The word "FR" refers to panels that contain fire retardant chemicals.
