Fire protected timber

Fire-protected exterior cladding is suitable for using at sites that have P1 or P2 fire cover categories (treatment facilities, public buildings). Industrial treatment ensures a multi-stage, certified and fire-protected wooden product. Initial treatment includes wood surface absorption of an agent that prevents blue stain fungus, mildew and rotting, after which the product is coated with fire-protected paint. Finally, the product is undercoated with the desired shade.

The benefits of industrial fire protection:
  • cost-effectiveness
  • protective treatment conducted under controlled conditions
  • on-site construction is speeded up
  • the highest fire-protection category P1 is achieved

All exterior cladding profiles are available with fire protection. The product information page shows the standard shades of primer in addition to e.g. profile images, dimensions, photographs and technical data.
