GranLux® FR – Next-Generation Fire Retardant for High-End Wood Protection

As modern architecture shifts toward sustainable wood construction, safety regulations demand high-performance fire protection. GranLux® FR is an innovative, eco-friendly fire retardant designed to replace traditional, toxic anti-fire treatments. It integrates seamlessly into industrial processes, delivering superior economic efficiency, functional durability, and environmental safety.

GranLux® FR is the premier choice for industrial manufacturers who refuse to compromise between structural performance, cost-efficiency, and ecological responsibility.

Optimal Applications

GranLux® FR is engineered for high-performance treatment of both solid wood and engineered timber products:

  • Engineered Timber: Ideal for mass timber products including LVL, CLT, and plywood.
  • Residential & Log Houses: Provides ultimate safety for modern log and wooden house manufacturing.
  • Industrial Post-Treatment: Compatible with various post-treatment surface finishing methods.

Unique Product Advantages

  • Premium Fire Protection: Easily achieves Euroclass B fire protection via surface treatment (≈ 200 g/m2) and meets the strict Non-Combustible class in Japan through pressure impregnation or immersion.
  • Novel Ecological Chemistry: Completely free from hazardous chemicals, heavy metals, bromates, fluorides, chlorides, borates, or acidic inorganic phosphates (such as MAP or DAP). Fully compliant with all strict EU safety regulations.
  • Preserves Wood Integrity: Formulated with a completely neutral pH (≈ 7), ensuring it does not reduce the natural strength or structural performance of the treated wood.
  • Seamless Process Integration: Easily adaptable to existing industrial manufacturing lines via surface treatment, immersion, or pressure impregnation.
  • Flawless Finish: Dries clear or slightly yellowish with a clean, non-sticky surface. Formulated to prevent crystal formation or the sticking of wood panels during industrial drying processes.
