Written by Liza Sivek | Tue, Apr 29, 2025 @ 09:04 AM

Builders and architects need dependable, quality wood for their exterior design projects. In areas with high fire risks, the lumber must meet strict fire codes, be durable, and look beautiful in finished projects. If your fire-resistant lumber projects need to last, discover this innovative FRTW wood solution.

Mataverde Saferwood Fire Retardant Treated Wood Decking and Dimensional Lumber

 

Designers and builders need fire retardant treated wood (FRTW) wood that meets fire safety criteria including Class A fire rating, International Wildland Urban Interface (IWUI) and Wildland Urban Interface (WUI). However, they also want lumber that:

  • Looks great in designs.

  • Is good for the environment.

  • Works for residential and commercial projects.

  • Is easy to get when you need it.

Mataverde® SaferWood provides an excellent solution without compromise. It offers high-level fire protection for all types of projects and is readily available in siding, decking, fencing, and dimensional lumber profiles. It carries a limited lifetime warranty for fire-resistance and is readily available from our West Coast distribution center. 

 

Why Choose A Different Fire-Resistant Lumber?

Builders know fire retardant treated lumber is important, however it also often required. Certified ignition-resistant wood is specified in wildfire-prone areas to help stop fires from starting and spreading. But types of fire retardant treatments for wood building materials vary in a big way. 

Therefore, Mataverde® SaferWood chose Thermex-FR treatment as the best choice to offer construction professionals. It has strong advantages over traditional surface treated lumber:

  • Can't be washed or worn off by weather: This is a permanent fire-retardant treatment bonded at the cellular level of the wood, not just the surface.

  • High-fire zone compliant for your projects:

    • It has a Class A fire rating and both IWUI and WUI approval.

    • It meets tough California Chapter 7A WUI requirements for ignition resistance

    • It passed the OSFM California 10-year outdoor weathering test, giving it proven durability.

  • Peace of mind for homeowners: Has our limited lifetime warranty for fire resistance.

  • Safe for people and animals: It's treated with only non-toxic ingredients and approved for indoor and outdoor use.

  • Excellent sustainability: Since we use Thermex-FR treatment the wood is non-leaching, environmentally friendly, and even recyclable.

  • Design options: Mataverde SaferWood can be used in many applications and can be finished.

Why FRTW Kiln-Dried After Treatment (KDAT) Wood is Better

First, Mataverde® SaferWood is treated with Thermex-FR fire retardant treatment under pressure. This gives exceptionally long-lasting protection for decks, fences and supports.

Then it's kiln-dried for excellent durability and low moisture content. This ensures your project maintains its strength and stability for an exceptionally long period of time. We confidently offer a Limited Lifetime Warranty for fire resistance on Mataverde SaferWood products.
