FASCIA – a profile, which is fixed to the lower ends of rafters and usually supports the guttering. FASTENER – a nail, screw or rivet used to fasten metal roofing or wall cladding to the structure. FIBRE CEMENT – a building board composed of cellulose fibres and cement. FINIAL – a decorative fitting used at the junction of ridges and hips and at the top of conical, pyramid or domed roofs. FIXING – the device used to fix or clip metal roofing or flashings. FLASHINGS – galvanised steel, lead, zinc sheet, etc. that is used to prevent water seeping through to an interior surface. FOOTING – that part of a construction designed to transfer loads to the supporting foundation, usually constructed of reinforced concrete to support base brickwork. FOUNDATION – the natural or built-up formation of soil, sub-soil or rock upon which a building or structure is supported. FURRING CHANNEL – battens fixed to the underside of trusses, rafters or ceiling joists to produce an even level ceiling. GABLE – the vertical triangular end of a building with a pitched roof, between the rafters from eaves level to the apex (ridge). It may be formed in brickwork or timber framed and clad with weatherboards. GABLE ROOF – a roof having two slopes only with a gable at each end. GALVANISING – the process in which steel is coated to prevent corrosion by dipping it into a molten zinc bath. GAUGE – an indicating device usually in brickwork setting out the number of bricks to a certain measurement. E .g. 7 brick courses per 600mm in height. This gauge is adjusted to suit the brick and the site conditions. GCI – galvanised corrugated iron, the old term for zinc-coated corrugated steel sheet and now usually but inaccurately used for corrugated ZINCALUME zinc/aluminium alloy-coated steel. GIRDER TRUSS – a truss that runs in the opposite direction to other trusses and has brackets (shoes) to carry and support the other trusses. The girder truss is often a double truss, made of hardwood in part or has bigger elements than other trusses. GIRT – horizontal members in a wall used to support wall sheeting. GOING – in a stair the horizontal distance from the face of one riser to that of the next. GRADE – the mechanical strength of a metal expressed in yield strength and measured in MPa. GYPSUM BOARD – a wall board made from plaster of Paris and covered with a stiff paper. HAMMER BEAM – the lower cantilever member in the roof truss of the same name. HANGING BEAM – a beam above the ceiling used to support ceiling joists. HEAD – the upper horizontal member at the top of an opening or frame. HEADER – a brick laid with its greatest dimension across a wall usually used to tie two skins together or under a door sill or window. HEARTH – the floor of a fireplace and immediately adjacent area. HERRINGBONE BOND –a brick bond giving a diagonal pattern in the form of a series of vees or inverted vees. HIP – the meeting line of two inclined surfaces. HIPPED ROOF – a roof which is pyramidal in shape with sloping surfaces and level edges all round. HIP RAFTER – the inclined member at the intersection of two roof surfaces. HOOP IRON STRAP – a strip of thin steel (usually about 25mm wide) which is usually built-into brickwork or nailed to frames as a tie-down for wind. IN-FILL CONCRETE SLAB – a concrete slab poured between base brick walls laid on concrete footings. An in-fill slab is supported by formwork or compacted filling. JACK RAFTER – the rafters running from a wall plate to the end of a ridge – sometimes called crown end rafters. JAMBS – the vertical sides of openings or the vertical timber fixed to the opening. JOISTS – horizontal structural members of steel or timber, spanning a room either to carry the floor or the ceiling.
