Charred Timber and ThermoWood Reshape UK Facade Design
A new study looks into how charred timber and ThermoWood affect facade design in the UK, emphasizing their durable, chemical-free properties and weather resistance. The Shou Sugi Ban technique is used for charred timber, where a controlled flame creates a carbonized surface that repels water, is biologically inert, and resists UV damage, lasting between 25 to 40 years. On the other hand, ThermoWood involves steaming Nordic pine or spruce at 185–215 degrees Celsius, reducing moisture uptake by up to 50% and achieving Durability Class 2 without preservatives. Both materials can be combined in projects, with charred timber as a standout feature and ThermoWood for secondary facades. They are available across the UK with nationwide shipping and can be treated to comply with Euroclass B fire ratings.
Key facts

- Charred timber has a service life of 25 to 40 years with minimal maintenance.
- ThermoWood absorbs up to 50% less moisture than untreated softwood.
- Both materials are produced without synthetic chemicals.
- Charred timber and ThermoWood can be combined on the same elevation.
- Both materials are available from UK stock with nationwide delivery.
- Factory fire retardant treatment can achieve Euroclass B classification.
