About Charred Timber

Permachar® timber has undergone fire treatment to preserve it. The Japanese call it “Yakisugi (焼杉)”. This charring process protects the wood against fire, wind, rain, rot and insects. It also substantially extends the natural lifespan of the wood.

The Benefits of Our Charred Wood Cladding...

Charring the surface of the wood without reaching complete combustion creates a carbon layer. This surface layer is water resistant which makes the wood beneath more durable.

The PermaChar process changes the chemical composition of the wood. This means the nutrition sources that fungus and mould spores need are removed.

The source timber used is sustainable and FSC® certified (FSC-C109654), this ensures forests are managed properly and ethically.

The unique PermaChar process creates a surface that is inhospitable to insects and pests which deters them from damaging the cladding.

In order for the charred cladding or fencing to re-ignite, it requires much higher temperatures and longer contact with a flame source.

We only use high quality, durable timbers. This coupled with the charring process, produces a wood which has a very long life span. Many Japanese examples last well over 50 years.

Our charred timber cladding comes in a choice of char levels and colours. All of our firing levels are deeply charred providing the benefits of our system and then brushed back to achieve the desired look. The charring process is carried out in our high tech facility, giving us control over speed of transit and heat which ensures a consistent and professional end result.
