ThermoAsh (Fraxinus Excelsior)

A-graded ThermoAsh is a top-tier, thermally modified hardwood that stands out for its durability, stability, and rich appearance. Through a chemical-free heat treatment process at high temperatures (around 200°C), the wood becomes highly resistant to decay, moisture, and insect damage, making it ideal for outdoor applications like cladding, decking, and furniture. The “A-grade” designation means that the wood is of the highest quality, featuring minimal knots or imperfections, giving it a smooth, refined finish that’s perfect for premium projects.
