Why Use Mataverde+ Thermally Modified Wood for Your Outdoor Projects?  

Superior Stability

Mataverde+ Thermally modified wood is remarkably stable, meaning minimal movement over time. While all wood expands and contracts with moisture, thermally modified wood exhibits significantly less shrinkage and expansion compared to non-modified woods, ensuring a long-lasting, reliable material.

Unmatched Durability

The thermal modification process permanently alters the wood at the cellular level, making it resistant to rot and undesirable to insects. This increases its lifespan, making it a cost-effective, highly durable, long-lasting choice for exterior applications.

Sustainable and Local

Mataverde+ Thermal modification enhances the performance of Western Hemlock, American Ash, Poplar, Southern Yellow Pine, and other sustainably harvested North American wood species. The result is high quality domestic woods that rival tropical hardwoods in performance and beauty, while keeping a lower carbon footprint.

100% Natural & Chemical-Free

The best thermal modification methods use only heat, steam and pressure—no chemicals, no toxins. This creates a high-performance, eco-friendly material suitable for decking, siding, and architectural applications. Whether you’re designing a stunning deck, recladding a building, or creating an award-winning architectural masterpiece, Mataverde+ Thermally Modified Wood offers a superior, reliable solution.
  
  

Thermally Modified Wood Pros and Cons

Pros:

  • Superior Stability – Less expansion/contraction than untreated wood.
  • Increased Durability – More resistant to rot, mold, and insects.
  • Enhanced Appearance – Richer tones, reduced color variation.
  • Sustainable & Eco-Friendly – Local, chemical-free alternative to tropical hardwoods.
  • Better Performance – Less warping, splitting, and cracking.
  • Cost-Effective in the Long Run – Longer lifespan reduces replacement costs.

Cons:

  • 🔸 Slightly Higher Upfront Cost – While the initial price is higher than untreated wood, it pays off in longevity and reduced maintenance.
  • 🔸 Darkening Over Time – Exposure to sunlight can further darken thermally modified wood, though this can be managed with UV-protective finishes.
  • 🔸 Slightly More Brittle Than Non-Modified Wood – The ThermaWood process actually strengthens the wood compared to other thermal modification methods. Other thermal modification techniques make the wood more brittle than the original wood. Careful handling is required.
