Wicket door A small door for one person in the leaf of a large entrance door to a factory or a warehouse
Wide-ringed timber Timber with annual rings which are far apart owing to a high rate growth
Width of the road The whole extent of spaces within the boundaries of road when applied to a new road, as laid down in the surveys of the city or development plans and measured at right angles to the course or intended course or direction of such road.
Wind beam A collar beam
Wind, winding The twist of converted timber. It is a type of warp
Winder A tapered tread in a turning part of a staircase (or circular stair) radiating from a common springing point at the newel post
Window An opening to the outside other than a door which provides all part of the required natural light or ventilation or both to an interior space and not used as means of egress / ingress.
Window back The vertical paneling or lining material between the floor and the window sill
Window Bar A glazing Bar
Window board A horizontal board (or other material) fixed under a window sill inside a window
Window casing The traditional timber cased frame of a sash window

Window sill A horizontal ledge below a window. The outside is weathered outwards and has a throat or drip underneath to protect the top of the breast wall against rainwater and to prevent waterstreaks on the wall
Window unit A unit air conditioner fixed in a window
Wing nut A nut that can be tightened or removed without tools by turning it with figures
Wiped joint A bulging joint round the outside of a lead pipe, made by wiping on heated solder with a cotton
Wiping seal A strip rubber blade seal or a fibre brush seal
Wire brush A tool used for cleaning metals before painting
Wire gauge A method of defining wire diameter by a number, which stated originally the number of passes made through different, increasingly smaller dies. The number of for large wire is therefore smaller than for thin wire
Wire management The prewiring of movable equipment or ensuring that trunking for wiring is big enough over its full length for all present and future needs
Wire nail A nail made by cutting and shaping a piece of round or elliptical steel wire
Wirecut brick Clay bricks made by extruding a strip of clay through a die and cutting it with wires held in frame, followed by drying and firing
Wired glass Flat glass reinforced by embedded wire mesh which holds the pieces together if it breaks. It is mainly used as fire-resisting glass
Wiring The cables, which carry electricity in a building, installed by an electrician.
Wiring diagram Usually a single-line diagram
Wiring in The connecting of cable tails to fittings, usually done after the main wiring and requiring coordination with other trades
Wiring loom A bundle of cables, prefabricated to save time on site
Withdrawable switchgear Plug-in switchgear
Withdrawn The positions of a door lock, bolt or latch, when it is retracted into the case, by turning a handle or key. The opposite is "shot" or "thrown"
Withdrawn load Wire nails driven across the grain are considered to have a safe pulling resistance of about 4.3 kg per cm length per 2.5 mm dia
Wobble saw A circular saw on a pair of tapered washers, making it slightly off perpendicular to the drive shaft to cut a wide herf. It is used in joinery for cutting open mortises
Wood Tough fibrous substance obtain from a tree
Wood borer A slow electric drill used to make holes with an auger bit
Wood brick A fixing brick
Wood chipboard Chipboard
Wood element A wood cell, botanically called xylem
Wood flour Fine sawdust, sometimes used as an extender for adhesives. It is also used in explosives as filler for plastic wood etc
Wood mosaic A warm, resilient, decorative wood block flooring of strips of hardwood 7.5 mm thick and 115 x 25 mm, made up into squares, then put together in a basket weave pattern as panels 475 m square. A sheet of paper on its top surface holds each panel together. It is laid in bituminous adhesive and the paper is removed after laying
Wood primer The first coat of paint on new wood, it should have the right moisture content, with a clean, dry surface. The primer used must be compatible with any preservatives in the wood. Primer should be brushed on and all end grain double primed
Wood roll A joint between bays of supported sheetmetal roofing hand made by folding the edges upwards on a sloping-sided or round-topped wood core. The joint is weatherproofed either by lapping the sheets to form an undercloak and overcloak (with a splash lap) or by turning up the edges and nailing down a capping
Wood screw A steel screw with a tapered gimlet point, a straight shank, and a countersunk, raised or dome head, traditionally with a straight slot
Wood slip A fixing fillet
Wood turning The skilled work of cutting wood to shape as it is spun round in a lathe, using chisels or gouges e.g. to make balusters
Wood-based panel products Panel products made of wood particles, veneers or blocks, bonded together with adhesive, natural resins or cement They include building boards, such as flakeboard, waferboard etc
Wood-block flooring A floor finish made of wooden flooring blocks, which usually have tongued and grooved edges. Blocks are 19 to 38 mm thick, up to 90 mm wide, and from 150 to 380 mm long.
Wood-boring weevil (Pentarthrum huttoni, etc) A borer which forms shallow channels in damp timbers, particularly if decay is already present
Wood-cement particle board A building board made of wood chips bonded with portland cement instead of resin based adhesives in normal wood chipboard. This helps it achieve a higher fire resistance rating. Both faces are smooth and suitable for most finishings, although it is mainly used for floating floors. It resists decay outdoors, if painted or sealed against rain, unlike chipboard bonded with urea-formaldehyde adhesives
Wood-heater A room heater made to burn wood. The wood should be as dry as possible, when it gives off most heat and does not blacken the glass in the fire door
Woodwool slab A panel product made of long thin strands of wood that are mixed with cement and compressed in a mould to bind them together. Woodwool slabs are mainly used for roof decks or wall cladding, giving fire resistance as well as heat and sound insulation. Another use is permanent formwork
Woodworking machines Bench mounted or stand alone power tools for shaping wood, such as doweller, mitre saw, mortising machine etc
Woodworm A borer usually the common furniture beetle
Work edge The face edge of timber
Work section A chapter of a specification that may describe a complete trade or a job done by a specialist sub-contractor
Workability How hard or easy a material is to cut, shape, drill etc

1) The swelling or shrinkage of timber causing movement as its moisture content becomes higher in winter and lower in summer, from changes in the relative humidity of air

2) Shaping materials by cutting, grinding, bending or folding if they are hard or by moulding, screeding, floating or toweling if they are wet or plastic

Working life The time, during which a product can be used after it has been mixed, before it sets or its curing system has been activated. Examples of product with working lives are adhesives, two part paints, sealants etc
Working space Clear space around a equipment or a machine to allow access and movement
Working-up The processing of data from taking-off. These are the two main stages in preparing bill of quantities. Working-up includes abstracting and billing
Worm hole The hole left in wood by a borer, either a small pinhole or a larger shothole
