Malvec Thermally Modified Timber.

Malvec is a thermally modified hardwood native to the forests of Central and West Africa. The tree is fast growing, typically reaching around 50m in height. The timber is then sent to Europe to be thermally modified.

Thermally modified timber means it has been heated up to 230 °C in the absence of oxygen. This process introduces chemical changes to the structures of cell wall components (lignin, cellulose, and hemicellulose) in the wood to increase its durability. The timber is heated in an environment with low oxygen to prevent burning at high temperatures.
Once thermally modified, the timber absorbs less water, consequently increasing decay resistance while decreasing swelling and shrinking. Thermally modified wood is far more durable than its previous state.

Manufacturing thermally modified timber requires a specially designed computer-controlled kiln oven to ensure every piece of timber is modified to the correct specification and quality. Mortlock Timber imports this already thermally modified timber direct from world class manufacturers using the latest technology in Europe and USA. Mortlock Timber then machines and manufacturers different products using this timber.

Malvec achieves a 1–2 Class durability rating according to EU standards, with a possible service life of over 50 years.
