Charred timber, also known as Shou Sugi Ban, is a traditional Japanese technique for preserving wood by burning it.
This method has been gaining popularity in recent years as a cladding material in architecture due to its unique aesthetic and durability properties.
One of the main advantages of using charred timber as a cladding material is its natural resistance to fire, rot, and insects. The charring process removes the wood’s cellulose and hemicellulose, which are the components that typically attract pests and decay. This makes it a low-maintenance and long-lasting option for exterior cladding. Co Create Architects have used this material on their project in the Teign Valley, Devon.
Additionally, the unique texture and colour of charred timber creates a striking visual effect that can add character and depth to a building’s façade. The variations in colour and texture that result from the charring process are unique to each piece of wood, giving a sense of warmth and natural beauty. The blackened surface of the timber also helps to visually reduce the size of the building and is also used as a way to blend into the background of the natural environment.
Another advantage of using charred timber as a cladding material is its environmental benefits. Timber is a renewable resource and using it as a cladding material can help to reduce the carbon footprint of a building. The charring process itself is also a low-energy method of preservation, making it a more sustainable option compared to chemical treatments.
Charred timber can also be used in combination with other cladding materials to create a more varied and interesting façade. For example, it can be used in combination with glass, metal, or stone to create a modern and contemporary look.
In terms of maintenance, charred timber cladding is relatively low maintenance, as the charring process makes it resistant to rot, decay, and insects. If the cladding does require cleaning, it can be simply be washed with water. Charred timber also has a natural resistance to UV rays, which means that it will not fade over time like other cladding materials.
Charred timber is a unique and durable cladding material that offers both aesthetic and functional benefits for architects and builders. Its natural resistance to fire, rot, and insects, combined with its striking visual appeal, make it an excellent choice for exterior cladding. Additionally, its environmental benefits and low maintenance requirements make it a sustainable option for architects and builders looking to create beautiful, long-lasting buildings.
