How Does Timber Material Works For a Long Run?

A tree that has just been cut down has a lot of moisture. To become usable timber it must be cut and dried. This process is known as transformation and seasoning. Some conifers can be treated with preservatives.

The tree's moisture content is higher outside than in the middle. So when dry timber dries, all planks, except those cut right in the middle of the tree, tend to warp. The planks should be flat after drying with the help of the best timber roof trusses in Newcastle, Sydney and surrounding areas.

Timber is dried either by stacking it outdoors or by drying it in the oven. Drying makes the timber stronger, more mildew resistant, and more suitable for painting and varnishing.

After timber dries, it can still absorb and lose moisture – it shrinks when it loses moisture and expands when moisture builds up. Timber stored outdoors shrinks when imported indoors, especially in centrally heated rooms. The effect on timber depends on the way the timber is cut – it is prone to deformation, while three-month-old timber tends to decline evenly. 

As timber moves between environments that tend to have very different humidity levels, it is important to give the timber time to balance with its new environment. This can only be a few days for small sizes, but more than a week for larger sizes.

Painting timber is important because it can hold water. Oil paint should be used on all exposed surfaces. Any timber chips or sawdust should be removed from the site. This will prevent the accumulation of insects or pests that threaten the house.
