Charred Timber - what are the benefits?Charring timber was developed by the Japanese as a wood preservation technique. They discovered that by creating a deep, controlled burn on the surface of Japanese Cedar panels, they could increase its durability. The striking finish has seen a resurgence across the globe and is being used in many contemporary designs.
- The finished effect of charred timber has a strong visual impact
- Another surprising benefit is that charring timber adds to its strength. You would think that removing an outer layer would weaken the wood. Instead, it actually draws moisture out and results in a stronger product
- Charred timber has a greater fire resistance - The process of charring timber increases its resilience to burning. This is because the process removes the soft outer layer, which is quick to ignite. The tough, lignin cells, which are left require considerably higher temperatures in order to catch alight.
- The carbon outer layer is a deterrent to insects
- The charring of the wood draws out natural resins and leaves a layer of carbon on the surface making it weatherproof
