Veneer, plywood and laminate glossary

This glossary explains the terms used when choosing veneer, plywood, laminates and decorative boards in India, from veneer cuts and matching to board grades and BIS standards. Each definition is written to stand on its own, with a link to a longer guide where a term needs more context.

#

8 x 4 sheetalso 8 x 4 ft, 2440 x 1220 mm
An 8 x 4 sheet is the standard panel size in the Indian plywood, laminate and board trade, measuring 8 feet by 4 feet, nominally 2440 x 1220 mm. Most veneers, plywood and pre-laminated boards are sold in this format, so the number of sheets a project needs is usually worked out against it. Read: How many veneer sheets do I need? A simple estimate

A

Acclimatisationalso Conditioning
Acclimatisation is the practice of letting veneer, plywood or boards rest in the space where they will be installed, so their moisture content settles to that room before cutting or pressing. It reduces later movement, gaps and warping, and matters most when stock moves between dry and humid conditions, such as during the monsoon. Read: Veneer and plywood in the monsoon: storage and care

B

Balancing sheetalso Backer, Liner, Balancing laminate
A balancing sheet is a layer bonded to the back of a panel to match the pull of the decorative face, so the board stays flat as humidity changes. With laminates it is usually a thinner, plain laminate called a liner or backer; with veneer it is often a second, lower-grade veneer. Read: Laminate thickness and finishes: 0.8 mm vs 1 mm explained
BIS (Bureau of Indian Standards)also Bureau of Indian Standards
BIS, the Bureau of Indian Standards, is India's national standards body, operating under the Bureau of Indian Standards Act, 2016. It publishes the Indian Standards (IS) that define plywood, board and laminate grades, and runs the product certification scheme behind the ISI mark. Read: Reading a plywood specification
Blockboardalso Block board
Blockboard is a panel with a core of solid wood strips laid side by side, faced on both sides with veneers whose grain runs at right angles to the strips. It is commonly used for long shelves, doors and large flat panels. In India it is specified to IS 1659. Read: Reading a plywood specification
Book-matchalso Book matching
Book-match is a way of laying up veneer in which every second leaf is turned over, so neighbouring leaves mirror each other along the joint like the pages of an open book. It creates a symmetrical pattern, and alternate leaves can catch the light slightly differently. Read: Book-match or slip-match: laying up a panel
Burlalso Burr
Burl is a figured veneer cut from a rounded outgrowth on a tree's trunk or roots, where the grain swirls around clusters of small dormant buds, often called eyes. Burl leaves are irregular and usually small, so they are used for accents, inlays and statement panels. Read: Burl, crotch and figured veneer: where they suit
BWP gradealso Boiling water proof
BWP, or boiling water proof, is the highest water-resistance grade of plywood bond in Indian standards. It is one of the three grades of general-purpose plywood under IS 303:2024, above MR and BWR, and is the bond required for marine plywood to IS 710. BWP bonds are typically made with phenolic resin. Read: MR vs BWR vs BWP vs marine plywood: grades explained
BWR gradealso Boiling water resistant
BWR, or boiling water resistant, is the middle of the three grades of general-purpose plywood under IS 303:2024, above MR and below BWP. Its adhesive bond is tested to survive cycles of boiling water and drying, which makes it a common choice for kitchens, bathroom vanities and other damp interior areas. Read: MR vs BWR vs BWP vs marine plywood: grades explained

C

Compact laminatealso Compact HPL
Compact laminate is a high-pressure laminate made thick enough, generally 2 mm and above, to be used as a panel in its own right rather than bonded to a board. Thicker compact sheets are self-supporting, which suits toilet cubicles, lockers, worktops and laboratory surfaces. Read: Laminate thickness and finishes: 0.8 mm vs 1 mm explained
Core
The core is the inner layer or layers of a panel, between its face veneers or decorative surfaces. In plywood it is made of cross-laid veneers, in blockboard of solid wood strips, and in MDF or particle board of bonded fibres or particles. The core largely decides a board's strength, weight and screw holding. Read: Reading a plywood specification
Crossbandalso Crossbanding
A crossband is a veneer layer in plywood laid with its grain at right angles to the layers beside it, usually directly beneath the face and back veneers. Crossbanding spreads strength in both directions and limits shrinking and swelling, which is why plywood stays flatter and more stable than solid timber. Read: Reading a plywood specification
Crotchalso Crotch figure, Feather figure
Crotch is a figured veneer cut from the point where a trunk divides into two branches, giving a flame or feather-shaped figure that rises up the leaf. It is highly decorative, can be brittle, and is used for accent panels and furniture faces rather than large plain runs. Read: Burl, crotch and figured veneer: where they suit
Crown cutalso Flat cut, Plain sliced, Cathedral grain
Crown cut is a way of slicing veneer flat through the log, parallel to its centre, so growth rings appear as arches, called cathedrals, down the middle of each leaf with straighter grain toward the edges. It gives the classic figure most people picture on a wood panel. Read: How veneer is cut, and why it changes the grain

D

Dyed veneeralso Coloured veneer
Dyed veneer is natural veneer coloured with dye, usually through its full thickness, so the colour stays even when the surface is lightly sanded. It is used to reach shades no species offers naturally, such as greys, blacks or bright colours, while keeping the real grain of the wood. Read: Types of wood veneer: natural, dyed, smoked and more

E

E0, E1 and E2also Emission class, E1 grade
E0, E1 and E2 are formaldehyde emission classes for wood-based panels, where a lower number means lower emission. Under the European system, E1 panels emit no more than 0.1 ppm in a chamber test and E2 panels emit more. E0 is not a European class but is used in some Asian standards for panels below E1. Read: E0, E1, E2: formaldehyde emission grades for plywood
Edge bandingalso Edge band, Edge tape
Edge banding is a thin strip of material bonded to the exposed edges of a cut board to cover the core, protect it from knocks and moisture, and match or contrast with the face. It is commonly made of PVC, ABS, laminate or real wood veneer. Read: Veneer, laminate or pre-laminated board?

F

Face veneeralso Face
A face veneer is the outermost veneer on the visible side of a panel, the layer that decides how it looks. On decorative plywood it is chosen for species, cut and match, while the back of the panel may carry a lower-grade or balancing veneer. Read: Reading a plywood specification
Figurealso Wood figure
Figure is the visible pattern on a wood surface, created by grain, growth rings, rays, colour and irregularities in the tree, together with the way the log was cut. Terms such as cathedral, ray fleck, burl and crotch each describe a different kind of figure. Read: Burl, crotch and figured veneer: where they suit
Fire-retardant plywoodalso FR plywood, IS 5509
Fire-retardant plywood is plywood treated with fire-retardant chemicals, usually by impregnation after manufacture, to slow the spread of flame and resist flame penetration. In India it is specified to IS 5509. It burns more slowly than untreated plywood but is not fireproof, since plywood is an organic material. Read: Fire-retardant plywood: what it does and doesn't do
Fleece-backed veneeralso Flexible veneer
Fleece-backed veneer is a thin sheet of natural wood veneer bonded to a non-woven fabric backing, which makes it flexible and less likely to split. It can wrap columns, curves and rounded edges that a standard leaf would crack on, and is applied with adhesive to a prepared substrate. Read: Types of wood veneer: natural, dyed, smoked and more
Flexible plywoodalso Bending plywood
Flexible plywood is plywood built to bend easily in one direction, typically by laying most of its thin veneers with the grain running the same way. It is used to form curved walls, rounded counters and columns, and is usually faced with veneer or laminate once shaped.
Flitchalso Sequence matching, Flitch matching
A flitch is the set of veneer leaves sliced from one log or log section, kept stacked in the order they were cut. Using leaves from a single flitch in sequence, called sequence matching, gives continuous grain and colour across a wall or a run of joinery. Read: Book-match or slip-match: laying up a panel
Formaldehyde
Formaldehyde is a colourless, strong-smelling gas used to make many of the resins that bond plywood, MDF, particle board and laminates. Small amounts can be released from some panels into indoor air, which is why boards are graded by emission class and low-emission grades are often specified for bedrooms and closed cabinets. Read: E0, E1, E2: formaldehyde emission grades for plywood

H

HDHMR boardalso High density high moisture resistant board
HDHMR, or high density high moisture resistant board, is a trade term for a dense fibre board made with moisture-resistant resins, designed to cope with humidity better than standard MDF. It is used for kitchen and wardrobe shutters and carcasses. Properties vary between makers, so ask for test data. Read: Veneer and plywood in the monsoon: storage and care
High-pressure laminate (HPL)also HPL, Decorative laminate, Laminate
High-pressure laminate, or HPL, is a decorative sheet made by bonding layers of resin-impregnated paper under heat and high pressure, with a melamine-resin decorative surface over a core usually treated with phenolic resin. It is hard and resists wear, scratching, stains and moderate heat. In India it is specified to IS 2046. Read: Laminate thickness and finishes: 0.8 mm vs 1 mm explained

I

IS 1328also Veneered decorative plywood
IS 1328 is the Indian Standard for veneered decorative plywood, meaning plywood with ornamental veneers on one or both faces. It covers decorative panels for furniture and panelling, and sets requirements for the face veneers as well as the bond and construction of the board beneath. Read: Reading a plywood specification
IS 2046
IS 2046 is the Indian Standard for decorative thermosetting synthetic resin bonded laminated sheets, the decorative high-pressure laminates used on furniture and interior surfaces. It classifies laminates by performance and use, and was revised in 2025 as a multi-part standard aligned with the international ISO 4586 series. Read: Laminate thickness and finishes: 0.8 mm vs 1 mm explained
IS 303also Plywood for general purposes
IS 303 is the Indian Standard for plywood for general purposes. The current edition, IS 303:2024, defines three grades by bond quality, MR, BWR and BWP, along with bending classes and appearance types (AA to CC) based on the quality of the two faces. Read: MR vs BWR vs BWP vs marine plywood: grades explained
ISI markalso BIS Standard Mark, ISI certification
The ISI mark is the BIS Standard Mark, shown on a product to indicate it is made under a BIS licence and conforms to the relevant Indian Standard. On plywood it appears with the IS number, such as IS 303 or IS 710. Government Quality Control Orders make it mandatory for many plywood and board products. Read: Reading a plywood specification

L

Leafalso Veneer leaf
A leaf is a single thin slice of veneer cut from a log. Leaves are kept in the order they come off the log, and several are joined edge to edge to cover a full panel, so the way they are matched shapes the finished surface. Read: How veneer is cut, and why it changes the grain
Liquid metal coatingalso Liquid metal, Cold-applied metal
Liquid metal coating is a decorative finish made from real metal powder, such as brass, bronze, copper or steel, suspended in a resin binder and applied cold by spray or brush. It gives a seamless metal surface over curves and shapes a metal sheet cannot wrap, and can be polished or aged to a patina. Read: Liquid metal coatings: what they are and where they work

M

Marine plywoodalso IS 710, BWP plywood
Marine plywood is plywood made for prolonged exposure to water, specified in India to IS 710 and bonded with BWP phenolic adhesive. The standard was written for boats, pontoons and similar uses, and the grade is also chosen in interiors where boards may get wet, such as sink units and bathrooms. Read: MR vs BWR vs BWP vs marine plywood: grades explained
MDFalso Medium density fibreboard
MDF, or medium density fibreboard, is a board made from wood fibres bonded with synthetic resin under heat and pressure, giving a smooth, uniform panel with no grain. It machines cleanly for routed shutters and painted finishes. In India it is specified to IS 12406 and is intended mainly for dry interior locations. Read: Veneer, laminate or pre-laminated board?
Melamine polishalso Melamine finish
Melamine polish is a clear wood finish based on melamine resin, sprayed over veneer to seal and protect it. It is widely used and economical, available from matte to gloss, but is generally less resistant to water, stains and sunlight than PU polish. Read: PU, melamine, lacquer or oil: how to polish veneer
Moisture contentalso MC
Moisture content is the weight of water in wood or a wood panel, expressed as a percentage of its oven-dry weight. Wood gains and loses moisture with the surrounding air, and the swelling and shrinking that follows is behind most gaps, cracks and warping in veneered work. Read: Veneer and plywood in the monsoon: storage and care
MR gradealso Moisture resistant, Commercial plywood
MR, or moisture resistant, is the interior grade of general-purpose plywood under IS 303:2024. Its bond tolerates humidity and occasional dampness but not boiling or prolonged wetting, so it suits furniture and panelling in dry interior areas rather than kitchens, bathrooms or other wet zones. Read: MR vs BWR vs BWP vs marine plywood: grades explained

N

Natural veneeralso Real wood veneer
Natural veneer is a thin slice of real wood cut directly from a log, so each leaf carries the actual grain, figure and colour of that tree. No two leaves are identical, which is why natural veneer is laid up in sequence and approved from samples of the actual stock. Read: Natural or reconstructed veneer?
NC lacqueralso Nitrocellulose lacquer
NC lacquer is a wood finish based on nitrocellulose, valued for fast drying and easy application. It gives a smooth clear or coloured coat but forms a softer film than PU polish, and is more prone to chipping and yellowing with age. Read: PU, melamine, lacquer or oil: how to polish veneer

P

Particle boardalso Chipboard
Particle board is a panel made from wood chips or particles bonded with synthetic resin under heat and pressure. It is flat and economical, and is most often used with a laminated surface for modular furniture and shelving. In India, medium density particle board is specified to IS 3087. Read: Veneer, laminate or pre-laminated board?
Patina
Patina is the change in colour and surface character a material develops with age, light and use. Wood veneers deepen or mellow in tone over time, and metals such as brass, bronze and copper darken or develop green oxidation, which some designs encourage deliberately through chemical ageing. Read: Caring for veneer surfaces
Plywoodalso Ply
Plywood is a panel made of thin wood veneers, called plies, glued together with the grain of each layer at right angles to the next. It is usually built with an odd number of plies so it stays balanced and flat, and it is strong, stable and holds screws well. Read: Reading a plywood specification
Post-forming laminatealso Postforming grade, PF laminate
Post-forming laminate is a grade of high-pressure laminate made to be bent around a curved edge with heat after it has been manufactured. It is used for rounded worktop and table edges and curved shutters, where a standard laminate would crack. Read: Laminate thickness and finishes: 0.8 mm vs 1 mm explained
Pre-laminated boardalso Pre-lam, Prelam board
A pre-laminated board is a particle board, MDF or plywood panel supplied with a decorative resin-impregnated paper surface already bonded to both faces at the factory. It needs no separate pressing or polishing: it is cut, edge-banded and assembled, which suits modular furniture and storage. Read: Veneer, laminate or pre-laminated board?
PU polishalso PU finish, Polyurethane polish
PU polish is a clear polyurethane finish sprayed over veneer to seal and protect it. It cures to a hard film that resists water, stains and scratches better than melamine polish, and is available from matte to high gloss. It is common on kitchen, dining and door surfaces. Read: PU, melamine, lacquer or oil: how to polish veneer

Q

Quarter cutalso Quarter sliced, Quartered
Quarter cut is a way of slicing veneer from a log that has first been cut into quarters, with the blade meeting the growth rings at roughly a right angle. It produces tight, straight, evenly spaced grain lines, and in species such as oak it can reveal ray fleck. Read: How veneer is cut, and why it changes the grain

R

Random matchalso Random matching, Mismatch
Random match is a way of laying up veneer in which leaves are placed without a deliberate order, often mixing leaves from different flitches. It gives a casual, varied surface like solid boards, and accepts more variation in colour and grain than book-match or slip-match. Read: Book-match or slip-match: laying up a panel
Ray fleckalso Ray figure, Ray flake
Ray fleck is a figure of shiny flecks, ribbons or flakes that appears when veneer is cut along the medullary rays, the thin bands of cells running outward from the centre of a log. It is most pronounced in quarter-cut oak. Read: How veneer is cut, and why it changes the grain
Reconstituted veneeralso Engineered veneer, Reconstructed veneer, Recon veneer
Reconstituted veneer is an engineered veneer made by dyeing leaves of a fast-growing wood, gluing them into a block and slicing the block again, so the glue lines form a new, designed grain. It gives highly consistent colour and pattern across large areas and can imitate scarce species. Read: Natural or reconstructed veneer?
Rift cutalso Rift sliced, Comb grain
Rift cut is a way of slicing veneer at an angle to the growth rings, between flat and quarter cut, chosen to give a straight, narrow grain with little ray fleck. It is used mainly on oak, where it produces a calm, linear surface often called comb grain. Read: How veneer is cut, and why it changes the grain
Rotary cutalso Rotary peeled
Rotary cut is a way of peeling veneer by turning a whole log against a fixed blade, like unrolling a paper towel. It yields wide, continuous sheets with a broad, wandering grain, makes efficient use of the log, and is common for plywood cores and faces. Read: How veneer is cut, and why it changes the grain

S

Sheenalso Matte, Satin, Gloss, Suede finish
Sheen is the amount of light a finished surface reflects, usually described as matte, satin or gloss. It applies to both polishes and laminates: higher sheen looks brighter but shows fingerprints and scratches more, while textured laminate finishes such as suede add a soft, low-sheen feel. Read: Laminate thickness and finishes: 0.8 mm vs 1 mm explained
Slip-matchalso Slip matching
Slip-match is a way of laying up veneer in which consecutive leaves are slid across side by side without flipping, so every leaf shows the same face. The grain repeats along the panel instead of mirroring, giving an even rhythm and a consistent sheen. Read: Book-match or slip-match: laying up a panel
Smoked veneeralso Fumed veneer, Fumed oak
Smoked veneer is veneer darkened by exposure to ammonia fumes, which react with the natural tannins in the wood. Oak, rich in tannin, is the classic choice, and results range from warm brown to almost black. Because tannin content varies, smoked veneer shows natural shade variation.
