Can you tell me about the environmental credentials of the oak you supply, and how important is that Hewins uses only responsibly-sourced materials?
Oak is a totally sustainable resource – but only when managed correctly – and therefore we strongly promote the importance of environmental management. The future of Hewins depends on the long-term availability of hardwood timber, and the future of the entire planet depends on everyone to play their part in carefully using this valuable resource. The majority of our stocks hold FSC® or PEFC™ certification, and this has been maintained by an annual audit since 2006 to make sure we are actively contributing to a sustainable future for all.
As a trusted timber supplier for Sitting Spiritually, can you tell me what makes oak such a brilliant material for outdoor furniture?
The main advantage of oak is its durability – it is stronger and harder than most other timbers and lasts for decades. Thanks to a wonderful thing called tyloses, it has a structural ability to repel water, which also helps it resist rot. Tyloses is a type of cellular growth that fills the pores of the wood, preventing water from being able to penetrate the wood - one reason why oak has been a favourite to build ships and barrels. Oak also has high levels of tannic acid, which acts as is a natural preservative and pesticide. Finally, not only is oak strong and durable, but it also looks beautiful. The classic, golden-brown colour never goes out of style and works in any outdoor environment.
How long does the oak drying process take before it’s ready to be used, and what are the advantages of using air-dried oak—which many of the Sitting Spiritually furniture range is built from?
Traditionally, the rule of thumb was to dry ‘a year per inch, plus a year’. This context can still loosely be applied today although – with modern equipment – it now tends to be governed by regular testing of the moisture content throughout the process. Air dried timber has been dried naturally in a covered, outdoor environment (e.g. an open barn) and results in a stable product that is very well suited to external applications. As the Sitting Spiritually furniture range is designed to used/stored outside, air-drying ensures that the timber is at a suitable moisture content and will therefore not react adversely to the environment by either shrinking or expanding.
