As a natural product, timber is dependent on many environmental factors that contribute to the colour and character of the finished product, including soil, climate and local environment. Timber can have natural variation in the one piece also. Usually this characteristic is not visible until the timber is finished. Light is also another factor in how finished timber will look as it can get lighter or darker depending on it’s location. Natural variation is one of the charms of timber and in particular recycled timber.

Moisture content of timber is critical to the finishing of your job, and with three kilns on site, Recycled Timbers can supply timber with the correct moisture content.

Our timbers that are kiln dried  are dried as per the Australian Standard AS2796.1 & AS2796.2 in accordance with AS/NZS 1080.1:1997.

The classification system is based on the assumption that the timber being dealt with is untreated, sound, mature heartwood of reasonable dimensions (at least 40 mm in thickness), used in ground contact unprotected from subterranean termite attack.

Class 1 – Timbers of the highest natural durability which may be expected to resist both decay and termite attack for more than 40 years (above ground exposed) and at least 25+ years (in-ground contact).

Class 2 – Timbers of high natural durability which may be expected to have a life of 15 to 40 years (above ground exposed) and 15 to 25 years (in-ground contact).

Class 3 – Timbers of moderate durability which may be expected to have a life of 7 to 15 years (above ground exposed) and 5 to 15 years (in-ground contact).

Class 4 – Timbers of low durability which may last less than 7 years (above ground contact) ad less than 5 years (in-ground contact).  These timbers have about the same durability as untreated sapwood, which is regarded as Class 4, irrespective of species.
