- Chipboard
- Blockboard
What is MDF?
- A smooth and even surfaced board made from combining wood powder and PVA glue
- Easily machined and painted
What are the uses of MDF?
- Used mainly for furniture and interior panelling due to its easy machining qualities
- Often veneered or painted
What is Plywood?
A very strong board, which is constructed of layer of veneer or piles which are glued at 90 degrees to each other
What are the uses of Plywood?
- Used for strong structural panelling board used in building construction
- Furniture making
What is chipboard?
- A board made from chips of wood glued together
- Usually veneered or covered in plastic laminate
What are the uses of chipboard?
- Used for kitchen and bedroom furniture usually veneered or covered with a plastic laminate (melamine)

Similar to Plywood but the central layer is made from strips of timber
What are the uses of blockboard?
- Used where heavier structures are needed
- Common for shelving and worktops
What are the 6 types of knock-down fittings?
- Plastic Corner Block
- Natural Wood Fitting
- Two Block Fitting
- Rigid Joint
- Scan Fittings
- Cam Locks
What is a Plastic Corner Block?
- The corner block is pressed against two pieces of wood and screws are used to fix the blocks into position
- A relatively strong joint that can be disassembled using a screwdriver
What is a Natural Wood Fitting?
- An effective and low-cost joint that uses a piece of Softwood, which is drilled and countersunk screws attached
- This gives a cheap and effective known-down joint
What is a Two Block Fitting?
- A strong joint that uses plastic fittings
- A bolt passes through the first fitting into the thread of the second
- As the bolt is tightened, it draws the two fittings together
What is a Rigid Joint?
- A strong joint because it uses Injection Moulded plastic fittings.
- Screws pass through the four holes which hold the sides at each corner firmly together
What are scan fittings?
- A strong joint that can either permanent or temporary joints
- The cylinder is inserted into the first side of a cabinet in a pre-drilled hole
- The screw is then pushed throught the hole in the second side until it meets the cylinder
What are cam locks?
- A disk fits into a recess in the first side of the cabinet and rotates by inserting a screwdriver into the slot in its side
