Study Notes
- Softwoods are generally cheaper than hardwoods because they are more available and grow quicker.
- Man-made boards are cheaper than timbers because they are manufactured.
- Man-made boards come in a better variety of sizes, an advantage that they do not depend on tree growth.
- Stock forms for both hardwoods and softwoods include sheets, dowel, and planks.
Hardwoods
- Hardwoods come from Deciduous Trees.
- Deciduous trees loose leaves in the winter, and grow fruit and flowers in the spring.
- Ash is flexible, tough and shock resistant, thus useful in sports equipment and tool handles
- Beech has a fine finish and is tough and durable, so is used in toys, furniture, and veneers.
- Mahogany is easily worked, durable, with a high quality finish, ideal for high-end furniture
- Balsa is very soft and spongy and light, thus useful for modelling
- Oak is tough, durable, and hard, so is used in flooring, furniture, and veneers.
Softwoods
- Softwoods come from Coniferous Trees, which have thin, needle-like leaves and grow all year round.
- Coniferous Trees often have pine cones and sometimes nuts and seeds.
- Larch is durable, tough, with good water resistance and finishes well, this makes it useful in furniture, flooring, and outdoor applications
- Pine is light and easy to work with, but can split, making it relevant for cheap furniture, construction, and decking
- Spruce is easy to work with, has high stiffness, but can decay quickly, appropriate for furniture, musical instruments, and construction
Man-Made Boards
- Manufactured boards are made from wood chips/dust/ layers and glue.
- Chipboard is prone to chipping but offers good compressive strength and is not water resistant
- Applications for chipboard include flooring, low-end furniture, and flat-pack items
- MDF is rigid and stable, easy to finish, but absorbs liquid easily
- MDF is used in flat-pack furniture and kitchen units
- Plywood is very stable, and exterior veneer can be used from more expensive woods
- Plywood is used to make Shelving, furniture, and toys
Primary Processing
- Trees are cut then converted into planks by using saws.
- Wood is seasoned to reduce moisture content through air-drying or kiln-drying.
- Air-drying involves stacking planks and allowing air to circulate, causing evaporation.
- Kiln-drying involves placing planks in a kiln for rapid drying, but it is more costly than air-drying.
- Manufactured boards are made by lamination or compression.
- Lamination involves layering wood and adhesive, compressing them together; often uses more expensive wooden veneer on top.
- Compression involves shredding, heating, and compressing wood with adhesive under extreme pressure.
