What this topic is asking
WJEC's materials content includes timber: natural woods and the manufactured boards made from them. You need to distinguish hardwoods from softwoods with named examples, and know the main manufactured boards and their uses. This is core knowledge for Unit 1, and central to the Product Design route.
Hardwoods and softwoods
Named timbers and their uses
Manufactured boards
Why use a manufactured board?
Manufactured boards solve problems of solid timber: they come in large sheets with no knots and no single grain direction, so they are stable and do not warp the way a wide solid board can. They are usually cheaper and make better use of the tree, including offcuts and lower-grade wood. Their drawbacks are weight, a duller appearance, and that some give off dust or use adhesives, so cut edges often need covering.
Try this
Q1. Name a hardwood and a softwood and give a use for each. [4 marks]
- Cue. Hardwood: oak (furniture). Softwood: pine (construction).
Q2. State one reason a designer would choose MDF over solid timber. [1 mark]
- Cue. Large flat sheets with no knots, stable and paints well.

A four mark Compare question. Hardwoods come from broad-leaved (deciduous) trees that grow slowly, so they are generally denser, harder and more expensive; an example is oak, used for quality furniture (2 marks for definition, example and use). Softwoods come from coniferous (evergreen) trees that grow quickly, so they are generally less dense, easier to work and cheaper; an example is pine, used for construction and cheap furniture (2 marks). Markers reward the broad-leaved versus coniferous distinction and a correct example and use for each. A common error is to assume hardwood is always physically harder than every softwood, which is not strictly true (balsa is a hardwood).
WJEC-style3 marksGive one advantage of using a manufactured board such as MDF instead of solid timber, and name a suitable use.Show worked answer →
A three mark question. An advantage of MDF is that it is available in large, flat sheets of even quality with no knots or grain direction, so it is stable and does not warp like solid timber (1 mark), and it is cheaper than solid hardwood (1 mark). A suitable use is flat-pack furniture or a painted cabinet, because its smooth surface paints well (1 mark). Markers reward a property-based advantage and a sensible use. A common error is to give a use with no advantage, or to forget that boards come in large sheets.
