ThermoWood® Exterior Cladding | Lunawood

Lunawood is a pioneer in decorative wood solutions, with 25 years of expertise in the thermal modification of wood. Their mission is to reconnect people with nature by bringing the calming essence of the forest into urban environments.

Lunawood ThermoWood® is manufactured from PEFC™-certified Nordic pine and spruce sourced from Finland’s cold forests. Through a chemical-free thermal modification process using heat and steam, the wood achieves improved dimensional stability, durability, and a darker tone, making it suitable for contemporary exterior cladding applications.

Lunawood ThermoWood® products for exterior cladding applications include planed and brushed cladding boards, tongue-and-groove profiles, and modular panel systems designed to support different façade configurations. The range includes standard siding boards in multiple widths and surface finishes, concealed-fixing panel systems and profiled boards that create shadow lines and textured surfaces for building envelopes. These cladding solutions are designed for horizontal or vertical installation and are suitable for residential, commercial, and public architecture.
