Fire Retardant Lunawood ThermoWood®

Lunawood offers several premium ThermoWood® products with impregnated BurnBlock® fire protection. The fire-retardant treatment enables the use of Lunawood ThermoWood® in buildings requiring a fire class B rating.

Lunawood ThermoWood® meets the required fire class B

Lunawood ThermoWood® meets the required fire class B

The use of Lunawood in versatile projects with fire class requirements is subject to Euro code EN 13501. Processed with the pressure impregnation method, Lunawood Thermowood meets the required fire class B for facade structures. This further expands the possibilities of using Lunawood in sustainable architecture.

The used technology and method for fire protection is a documented, CE-marked treatment process which enables a consistent quality of fire protection. Planed, flat tongue & groove Lunawood products achieve fire class B-s1, d0, while 3D-Lunawood products are tested to meet fire class B-s2, d0.
For outdoor use, the minimum requirement for Reaction to Fire is B-s2, d0. For indoor use, it is B-s1, d0.

The same visual appearance with enhanced fire class

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 offers also painted fire retardant products conducted by a CE-certified painter partner.

Painted Finishes for an Instant Grey or Black Look

Painted Finishes for an Instant Grey or Black Look

For those projects where a uniform shade of grey is desired from the outset, Lunawood provides options in mid-grey and light grey. The grey surface treatment on Lunawood subtly fades over time due to weather exposure, revealing the naturally greyed wood beneath. Importantly, the fire protection properties are maintained throughout the product’s lifespan. In addition to the grey surface treatment, the black painted, fire-retardant Lunawood products offer a bold, sophisticated choice for modern facades. Lunawood’s fire-retardant and surface-treated products have CE certification.

The maintenance of fire-retardant and painted Lunawood ThermoWood® varies depending on location, but the fire protection treatment itself does not require renewal. Lunawood’s fire-retardant painted solutions are intended for outdoor use only.
