The same visual appearance with enhanced fire class

Throughout impregnated fire protection does not affect neither the visual appearance nor the original technical properties of Lunawood Thermowood. The surface of the fire retardant Lunawood turns gray under the influence of UV radiation, just like untreated Lunawood. This enables a natural gray end result for the project.
The fire retardant treatment is durable in all climates. Lunawood also offers painted fire-retardant products in custom colors, finished by a CE-certified painting partner.
