Timber and wood are often used interchangeably, but they are not actually the same thing. While both timber and wood come from trees, there are some key differences between the two.
Timber refers to wood that has been processed for construction purposes, such as building materials and furniture. It is often cut and shaped to specific dimensions and is typically stronger and more durable than raw wood.
Wood, on the other hand, is the raw material that comes directly from trees. It can be used in its natural state for things like firewood or craft projects, or it can be processed into timber for larger construction projects.
The Definition of Timber
Timber is a type of wood that has been processed for use in construction, furniture making, and other applications. It is typically sourced from trees that have been grown and harvested specifically for their timber value.
Timber is known for its strength, durability, and versatility. It is commonly used in building structures, such as houses, bridges, and furniture.
Types of Timber
There are two main types of timber: hardwood and softwood. Hardwood comes from broad-leaved trees, such as oak, mahogany, and maple, while softwood comes from coniferous trees, such as pine, spruce, and fir.
Characteristics of Timber:
- Strength: Timber is known for its strength, making it a popular choice for structural applications.
- Durability: Timber is resistant to rot, decay, and insect damage, making it a long-lasting material.
The Definition of Wood
Wood is a natural material derived from trees and is used for various applications in construction, furniture making, and other industries. It is composed mainly of cellulose fibers embedded in a matrix of lignin, hemicellulose, and extractives.
Wood can be classified into two main categories: hardwood and softwood. Hardwood comes from deciduous trees such as oak, maple, and walnut, while softwood comes from coniferous trees like pine, spruce, and cedar.
Physical Characteristics of Timber
1. Density
The density of timber refers to the mass of the wood per unit volume. It is an important factor in determining the strength and durability of the timber. Hardwoods generally have a higher density than softwoods, making them stronger and more suitable for heavy-duty applications.
2. Grain Pattern
The grain pattern of timber is determined by the alignment of the wood fibers. It can affect the appearance and strength of the timber. For example, straight-grained timber is usually stronger and less prone to warping, while interlocked grain can make the wood more difficult to work with.
| Physical Characteristic | Description |
|---|---|
| Color | Timber can have a wide range of colors, depending on the species of tree it comes from. This can range from light yellows and browns to dark reds and purples. |
| Texture | The texture of timber refers to the smoothness or roughness of the wood surface. Some timbers have a smooth, fine texture, while others may be coarse and grainy. |
| Moisture Content | The moisture content of timber is important for its stability and usability. Wood with high moisture content is more prone to shrinking, warping, and decay. |
Physical Characteristics of Wood
Wood is a natural material that comes from the stems and branches of trees. It has unique physical characteristics that distinguish it from other materials:
1. Density
- Wood has a wide range of densities depending on the species of tree it comes from.
- Hardwoods, like oak and maple, tend to be denser and heavier than softwoods, like pine and cedar.
2. Grain Pattern
- The grain pattern of wood is determined by the arrangement of fibers within the tree.
- Some woods, like oak, have a pronounced and distinctive grain pattern, while others, like maple, have a more subtle grain pattern.
These physical characteristics not only affect the appearance of wood, but also its strength, durability, and suitability for different applications.

Durability of Timber vs Wood
Timber is known for its high durability due to its natural resistance to pests, decay, and rot. This is because timber is usually sourced from slow-growing hardwood trees that have dense fibers, making it tougher and more durable compared to wood.
On the other hand, wood is generally less durable than timber as it is often sourced from fast-growing softwood trees that have less dense fibers. This makes wood more susceptible to damage from pests, moisture, and wear and tear over time.
When it comes to outdoor applications such as decking, fencing, or siding, timber is preferred over wood due to its superior durability and longevity. Timber structures can last for decades with proper maintenance, while wood structures may require more frequent repairs and replacements.
In summary, timber is more durable than wood due to its natural properties and composition. When choosing between timber and wood for your construction projects, consider the level of durability required for the specific application to ensure the longevity and sustainability of the structure.
| Timber | Wood |
|---|---|
| High durability | Less durable |
| Natural resistance to pests, decay, and rot | More susceptible to damage |
| Sourced from slow-growing hardwood trees | Sourced from fast-growing softwood trees |
Cost Comparison Between Timber and Wood
When it comes to cost, timber is generally more expensive than regular wood. This is because timber is specifically cut and processed for construction use, making it more durable and of higher quality. On the other hand, wood is a more generic term that includes a wider range of products and can often be found at lower price points. However, the initial investment in timber may pay off in the long run due to its superior strength and longevity.
In addition, the cost of timber can vary depending on the specific type of wood, its quality, and availability in the market. Some high-end timber options can be significantly pricier than standard wood products, while more common timber varieties may be comparable in price to regular wood.
Ultimately, the cost comparison between timber and wood will depend on the specific project requirements, budget constraints, and desired outcome. It is important to weigh the cost against the quality and durability of the material to make the best decision for your construction needs.
