Euro Oak

Type: Hardwood
Source: European


The grain of European Oak is golden-brown in colour, which makes it a popular option for those looking for a more traditional style. Oak is naturally very durable, it machines well, but is more difficult to work with than softwoods. Steel screws should be used as oak reacts with iron. 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.

If you have decided that Timber Cladding is going to be one of the materials on your project the next step is to create a specification that will meet the criteria and expectations you, and your client have.

We offer installation guidance, detailing guidance based on TRADA documentation, with a wealth of knowledge and information on how different timbers will perform over the life span of your project.

Considerations that should be made when it comes to weather, along with how elevation and design variations can impact timber cladding.
