What is Seasoning Timber?

Seasoning of Timber involves hydrothermal treatment, which involves evaporation in the required proportion of moisture.

Timber seasoning improves timber strength, eliminates wood decay, prevents articles from changing in size and shape, and ultimately, improves the timber's finishing quality.

Seasoning wood serves the basic purpose of reducing the moisture content so that it can be used in articles.

Scope of timber seasoning

Here are some reasons why seasoning timber is necessary.

Seasoning timber can be economically beneficial because it reduces shipping costs.

Seasoning timber can reduce the timber's weight by a significant amount. This allows for easier transportation and lower fuel consumption.

The purpose of seasoning timber is to increase the durability of the component.

Seasoning timber is important to avoid insect damage and decay.

Seasoning is a process that prepares wood for injection with preservatives or for other industrial purposes.

Timber should not shrink beyond a certain value after being placed into service to ensure safety. Seasoning Timber can reduce timber's shrinkage.

Wood's decay is a prerequisite for moisture. Wood or timber that can be kept dry using the principle of seasonsing is less likely than wood that has been subject to decay.

Seasoning Timber can improve its ability to perform.

The following properties of wood are improved by timber seasoning

1. Strength

After seasoning, you will notice an increase in strength, particularly tensile and compressive, as well as bending. Seasoning Timber can also affect stiffness.

This means that buildings constructed under green strength ratings for timber are stronger when they dry.

2. Hardness

The hardness of seasoned timber in its wet state is much greater than that it has when it is dry. It is not recommended to drive nails into seasoned wood. However, it can be a benefit in that flooring and furniture are more resistant to knocking and bumping.

3. Weight

A reduction in the weight of timber by reducing its water content from its original green value down to 10 to 15% results in a significant decrease in weight. It's a great way to reduce the cost of transport and handle.

4. Durability

Timber with a moisture content of 24% or higher is more susceptible to staining and rotting fungi. This causes timber to soften and unattractive colors.

To prevent any degradation of the timber's appearance, it must be seasoned and kept at 24% moisture in a protected environment to ensure its indefinite existence.

5. Painting and finishing

Before painting, varnishing or polishing timber, it is essential to season it properly in order to achieve satisfactory results. Failure to follow the seasoning procedure could result in the surface coating becoming brittle, cracked, or peeling due to moisture.

6. Gluing

Timber quality is also a factor in the bonding of adhesives to timber. The timber must be properly seasoned before adhesives can form strong bonds. The adhesive's bonding strength is affected by moisture from the separating layer.

7. Resistant to Insect Attack

Unseasoned timber is more susceptible to insect attack. Seasoned timber has a smaller range of insect species susceptible to attacking timber.

Preservation to resist attack is used to treat certain species of insects. Sometimes partial seasoning is required in these cases.

8. Resistance to electricity

Seasoned Timber has an electrical resistance that is approximately one million times higher than regular timber. A good mix of moisture and green timber can conduct electricity well. However, dry timber acts as an insulator.

9. Heat content

Timbers of different types can be used to ignite, but they must have a high calorific value in order to easily burn.

Seasoning Timber gives timber a calorific worth of 16 to 19MJjk g. This allows wood to be ignited easily and burns in a more efficient manner, reducing pollution.
