Plywood
Cutting the veneer
Make-up of plywood– Veneers at 90° to each other– Odd number of layers (5/7)

Types of plywood
WBP– Water and Boil Proof– Exterior grade
Marine plywood– Boat building – Exposed situations, roofs

Blockboard
Strips of softwood glued together and faced with veneers
Does not split easilyCan screw into the edgeWide sheets (8’ X 4’)

Pineboard/lamwood
Made from thin softwood strips, glued together
Makes a wide board in softwood
Uniform thickness (12 – 25mm)Boards tend to cupUseful for projectsHardwood examples can be
obtained

ChipboardWood chips are glued Pressed into sheetsOften faced with wood veneer
or plastic laminateEdges of the board need to be
covered

Edges
• Edges of chipboard should be covered

MDF (Medium density fibreboard)
Very popular board materialOften faced with veneer or
plastic laminateMade with fine wood fibres
in three layersNeed to drill into face
before nails or screws are inserted
Fine dust is harmful

Hardboard
• Available in thin sheets • One face smooth, one
textured• Often faced with plastic
laminate• Back of cabinets, base of
drawers• Only used indoors

− Large sheet sizes− Cover large areas easily− Uniform thickness− Stable – no shrinkage− Do not warp− Use woods efficiently − Little waste − Often veneered over – helps to
save the rainforests
