18
Q

Properties of Plywood

A

-each layer at 90 degrees
-very STABLE against warping
-size not restricted by tree
-can be bent
-shrinkage almost ELIMANATED

19
Q

Properties of Blockboard

A

-strips placed edge to edge and placed between veneer of hardwood
-more durable than plywood but not as strong

20
Q

Properties of MDF

A

-uniform thickness
-easy to work with
-need respiratory protection & dust extraction
-can have veneers
-not good with water

21
Q

Properties of Chipboard

A

-wood particles glued together with adhesive (resin) and heat and pressure used
-unattractive edge

22
Q

Properties of Hardboard

A

-also called high density fibreboard
-has a smooth surface
-dense

23
Q

properties of OSB/ Sterlingboard

A

-mainly used for construction
-can be RESISTANT to FIRE

24
Q

Properties of cross laminated timber

A

-sustainable
-can be very big
-restricted by machinery size
-more expensive
-FIRE RESISTANT
-cleaner and drier construction site (not exactly sure why though)

25
Q

Definition of a veneer

A

Thin slices of wood which are glued onto the surface of a material for an enhanced and more decorative look

26
Q

Why are hardwoods generally used more as veneers

A

They are more DURABLE and DECORATIVE

27
Q

2 of the types of veneer

A

paperback and laminates

28
Q

What is formica and how is it made

A

-lots of paper stuck together
-decorative surface on top layer
-heat cured with resin
-so strong CROSS LINKS are formed

29
Q

What are knots

A

natural defects found in timber- the point where branches were grown from

30
Q

Definition of timber conversion

A

Sawing up logs to produce useable wood forms

31
Q

Process of timber conversion (5)

A

1- Mature trees felled (and replaced with saplings in managed forests)
2- Trees stored or transported
3- Trees enter saw mill
4- Planks trimmed wither side to remove bark
5- Wood left to SEASON (so it is less likely to warp or distort)

32
Q

What is a stock form

A

The way in which a material (?) can be supplied

33
Q

Wood stock form examples

A

dowel, rough sawn, sheet, moulding, planned square edge

A

Log just sliced along

35
Q

What is rift sawn wood

A

all wood cut at 90 degrees to the grain

36
Q

What is quarter sawn wood

A

wood cut into quarters then cut into planks in each quarter

37
Q

Properties of plain sawn wood

A

-most common
-most inexpensive
-most recognisable
-least stable

38
Q

Properties of rift sawn wood

A

-clean straight grain
-no ray fleck
-least efficient
-most expensive
-most STABLE

39
Q

Properties of Quarter sawn wood

A

-ray fleck (visual texture, provides EMPHASIS)
-in the middle stable
-in the middle expensive
-desirable aesthetic

40
Q

What is ray fleck

A

where the sap moves up the tree

41
Q

What in wood can be a hazard

A

toxicity of dust from wood and sap
