Oak Cladding timber is classified as a hardwood species mainly because of its density, which usually is above 670kg per cubic meter. Softwood has a particularly lower mass of around 390kg per cubic meter. With higher density, oak timber is not only heavier, but also stronger and more durable.
The toughness of Oak timber makes it a perfect material for exterior cladding, as it can withstand any weather conditions. Oak timber will also resist the other forces of nature, such as fungal attacks, termites, and moisture.
