POSSIBLE ANSWERS
 

1. Name a manmade board. Describe a typical use and explain why it is suitable.

 
MANMADE BOARD: Plywood
 
USE: Furniture
 
WHY SUITABLE:
Veneered plywood is suitable for the manufacture of furniture. Plywood is extremely resistant to warping, due to the way the various layers are combined. Plywood is available in the form of large boards, which removes the need to join smaller pieces together. Plywood is cheaper than natural wood and is sometimes composed of scrap / waste wood (recycled).
 
2. Name a natural wood. Describe a typical use and explain why it is suitable.
 
NATURAL WOOD: Scots Pine
 
USE: Roofing timbers
 
WHY SUITABLE:
Scots Pine, also known as redwood and red deal, when treated with preservatives, is suitable for both indoor and outside use. It is easy to cut and shape and is a reasonable strong natural wood, as well as being lightweight. Scots pine finished surface has an attractive yellow colour, that becomes more intense as the wood ages.
 
3. Describe three advantages that manmade boards have over natural woods
 
A. Plywood is extremely resistant to warping. This is due to the way the various plies are glued together. The grain of each ply is set at 90 degrees to the ones above and below, creating a warp resistant material. Plywood is an extremely stable manmade material.
 
 
B. Manmade boards of this type are supplied in a range of sizes and thicknesses. This is an advantage compared to natural woods, as manmade boards can be manufactured, so that they are extremely wide. This makes plywood a popular material in the construction industry.
 
 
C. Plywood has a wide range of uses. These include:

Softwood ply tends to be used in the construction industry for walls, roofs and floors.
Hardwood ply tends to be used quality laminate flooring, kitchen units and some furniture.
Marine plywood is used in boat hull construction. It is specially treated so that it is water resistant .
