Antique - Original timber of around 200 years old or more, either in original condition or re-machined to a specified size or finish.

Aged - A chemical process used to deepen and change the colour of new timber all the way through without need for staining. Creates an older appearance.

Adhesive - Commercial glues used to bond wood flooring to subfloors or together.

Basketweave - A patterened floor which comprises various interlocking blocks laid in sets of 4, with each set at a right angle to its neighbouring set of 4 blocks.

Brushed - A manufacturing process applied to the timber to texturise the surface. Usually carried out by copper brushes attached to the planer.

Bevelled edge - Term used to describe the edge of a plank which has bee chamfered off in the manufacturing process. Creates a groove or 'v' joint between boards when they are laid.

Chevron - A wood flooring pattern which uses interlocking pieces joined at a point to either a 30 or 60 degree angle.

Distressed - A process wood floors undergo to give a lived in look. Various techniques are used which result in planks carrying surface damage, dents, scratches and imperfections to both edges and face. Boards are than finished with oil to soften defects giving the appearance of a well worn although not necessarily period floor.

DPM - Damp proof membrane. A sheet polythene used under floors to keep moisture at bay. Expansion / Gaps - Space that is left around the perimeter of a wood floor to allow natural movement in the floor as it reacts to ambient and subfloor moisture. Typicall y arong 10mm gaps.

Engineered - A term to describe a multi layered wood flooring board comprising of a surface veneer of real timber (approximately 3.6 -4mm) bonded to a central softwood core and a counterbalancing backing of softwood. All layers together produce a 14mm thick board. Various width options available.

Floating Floor - A term used to desrcribe a wood flooring system that is not adhered to the subfloor via nails or adhesive. Boards are sat onto an underlay and glued together via the tongue and groove only. Most engineered wood floors are laid in this way.

Herringbone - A traditional pattern used in the past 100 years to create a interlocking pattern of blocks of around 8 inches long.

Hand Scraped - A process used to undulate the surface of wood floors to create an uneven surface which replicates foot traffic and wear characteristics of a floor around 200 years old.

Hardwax Oil - Surface finishing treatment made from natural vegetable oils, mixed with wax. Usually applies via 2 coats to bare timber.

Lacquer - or varnish, or seal. A surface treatment applied to bare timber to finish and protect. Usually 3 coats applied. Availaibe in matt, satin or gloss finishes.

Latex - a levelling compound. A 1 or 2 component powder mixed with water to be poured onto uneven concrete floors. Used to find dips or hollows, dries to level the overall subfloor prior to installing new floorcovering.

Mosaics - A term used to describe a basketweave floor pattern, supplied in sheets of fingers around 466mm square. A popular floor during the 1960's.

Natural Grading - A term used in a timber grading system. Usually a mid grade which allows colour variation to a timber, but limits knots or sizes of knots to create a cleaner look to a floor.

Overlay - A traditional method of wood flooring comprising square edged planks or pieces without a tongue and groove. Usually fixed to a timber or concrete base via pins and wood adhesive. Commonly used to create patterns.

Parquet - Either a European term used to describe wood flooring as a whole Or commonly used as a term for patterned floors such as herringbone in the UK.

Prefinished - Where wood flooring products have had a surface treatment already applied at the factory. Usually requires no site finishing after installation.

Plank - Wood flooring boards which are over 5" wide, either solid or engineered.

Quadrant - A convex shaped piece of timber supplied in around 2 -3 meter lengths in various hardwoods.Used to cover expansion gaps left around the perimeter of a wood floor.

Reclaimed - Timber which has been salvaged from use in various other locations, usually around 100 years old. This can have been flooring previously but can be used again.

Rustic Grade - A term used in the grading of wood flooring. This grade permits almost unlimited natural colour variation via sapwood and heartwood, also knots (usually around 2 - 4cm dia). Grading of wood floors is at the discretion of the manufacturer and can differ slightly from one to another Resin

Filler - A clear liquid product which is used to be mixed with sawdust yielded from a sanded wood floor. Mixed to a paste it allows gaps and knots to be filled in wood floors to best match the colour of the original timber.

Scotia - a concave or half round shape of timber usually supplied in 2 - 3 meter lengths in various hardwoods.Used to cover expansion gaps left around the perimeter of a wood floor.

Solid - Individual strips or planks of timber made from 100% hardwood. Usually from around 2" wide up to 10" depending on species. Supplied in random or set lengths, depending on supplier.Usually 20mm thick.

Semi Solid - A term used to describe a board around 20mm thick (similar to solid wood). Which comprises a real wood veneer around 5-6mm, bonded to a plywood base. Technically an engineered product but displays more similar properties to solid wood as it can be nailed down to provide a structural floor. Also has the same wear layer as a solid wood board. Available mainly in wider widths from around 6.5" up to 10".

Subfloor - what a floorcovering sits on. Either concrete, floorboards, chipboard. In older properties sometimes brick.

Secret nailing - A fixing method usually for solid wood floors. A 2" lost head nail is fired at 45 degree angle into the upper side of the tongue on a tongue and groove board. This embeds into a timber base on the other side, either plywood or joists / battens. Allowing the following tongue and groove system to the next board to hide the nails.

Strip - Term used to describe solid wood floors that are less than 5" in width.

Select grade - A term used within the grading system for wood flooring to describe timber selected out for colour. This in turn excludes the presence of knots and will represent an even colour as much as possible in a whole floor. Grading of wood floors is at the discretion of the manufacturer and can differ slightly from one to another.

Smoked - A process used to darken wood floors during the drying process. Whilst drying timber in a kiln, smoked floors are achieved by extending this period under controlled conditions to create an darker colour through the wood.

Tolerance - The allowable amount of deviation a subfloor may carry in order that a wood floor can be installed successfully.

Underlay - Wood flooring underlays, various types used with floating floors. Typically between 2mm - 4mm thick, some carry built in damp proof sheeting.

Unfinished - Unprepared raw timber requiring sanding and sealing after installation.
