Thermally Modified Ayous Channel Cladding Boards

Our Thermally Modified Ayous Channel Cladding Boards will create a stylish and modern impact on any project, thanks to the dark, rich, and vibrant earthy tones created from the thermal process.

The thermal process is an intelligent system that results in a hardwearing and low-maintenance timber with an impressive lifespan of anywhere between 15 to 25 years, longer if treated regularly.

The timber is placed in a special electric-powered oven which heats to 210 degrees Celsius while maintaining a low-oxygen environment using a vacuum process. The heat and pressure produce a transformation at a molecular level during a cycle that lasts around 20 hours. The peak temperature is reached via a controlled cooling process, whilst gases are condensed and stored for safe disposal, resulting in a 96% reduction of air emissions & an immaculate, green product compared with other thermal modification processes.

This unique method results in high-quality, incredibly tough products without the harmful emissions and toxic chemicals used through other similar processes.
