The word ‘fillet’ comes from the Latin ‘filum’, meaning ‘thread’
In classical architecture, a fillet is a narrow band with a vertical face. Fillets are often interposed as rectangular or square ribbon-like bands between curved mouldings and ornaments. They may also be found between the flutings of columns.
Types of fillet include:
- Raised: A fillet that is raised in a band from an architectural element.
- Scotia: A concave moulding between two fillets. This is also one of the elements used in the attic base of columns.
- Sunk: A fillet that is depressed in a band between two other architectural elements.
- Tænia: A fillet that is part of the entablature and positioned directly above the architrave.
In modern construction, the term ‘fillet’ can be used to refer to any thin strip of material, for example a tile fillet, in which roof tiles are set into mortar beneath a parapet to form a flashing, or a mortar fillet, used in place of a flashing at the joint between roof slates and a wall.
In engineering, the term ‘fillet’ can be used to refer to a round joint between two parts connected at an angle.
