Lunawood UTV Thermo-D RW A is a type of thermally modified wood product manufactured by the Finnish company Lunawood. The UTV (Ultra Thick Veneer) Thermo-D process involves treating the wood with heat and steam, which changes the properties of the wood and makes it more durable, stable, and resistant to decay and weathering.

The RW A designation refers to the grade of the product. The RW grade indicates that the wood is knot-free on one face, while the A grade refers to the overall quality and appearance of the wood, which is typically of a higher standard.

Lunawood UTV Thermo-D RW A is often used for cladding, decking, and other exterior applications, as well as for interior design and furniture. The thermal modification process gives the wood a beautiful, rich, and uniform colour, which can vary from light to dark brown depending on the intensity of the treatment.

In addition to its aesthetic qualities, Lunawood UTV Thermo-D RW A also has excellent dimensional stability and resistance to moisture, making it a popular choice for projects in challenging environments. The product is available in various sizes and profiles, and can be used for both residential and commercial applications.
