Thermally Modified Wood: A Smart Choice for LEED-Certified Projects

When it comes to sustainable building materials, thermally modified wood is rapidly becoming a favorite among architects, builders, and designers working on LEED-certified projects. Tougher than untreated lumber, yet free from harsh chemicals, it stands up to warping, swelling, and decay with ease. It’s ideal for siding, decking, and interior finishes that look stunning and last for years. And because the modification process is entirely eco-friendly, it’s as smart for the planet as it is for your project.

Why It Works for LEED Thermally modified wood contributes to LEED certification in multiple ways. Its production process is completely free of harmful chemicals, relying instead on heat and steam or pressure to enhance the wood’s performance. This ensures both environmental safety and occupant health.

Sustainability at Its Core Because the modification process improves durability and dimensional stability, thermally modified wood extends the lifespan of any structure it’s used in—reducing the need for replacements and minimizing waste over time. It can be sourced from responsibly managed forests, supporting both environmental and economic sustainability.

Better for Indoor Air Quality Low- or zero-VOC finishes mean thermally modified wood can be safely used indoors without contributing to poor indoor air quality, helping projects meet stringent LEED indoor environmental quality requirements. ThermalPro Wood uses all-natural, low-VOC finishes, delivering rich color and lasting performance—without a trace of harsh chemicals.

Durable, Beautiful, and Responsible From siding and decking to interior paneling and cabinetry, thermally modified wood combines long-lasting performance with natural beauty. Its resistance to warping, rot, and insect damage makes it a smart choice for any project aiming to meet both aesthetic and environmental goals.

How Thermally Modified Wood Supports LEED Certification

Thermally modified wood can contribute to earning LEED points in several categories:

• MRc2: Building Product Disclosure and Optimization – Material Ingredients

  Recognizes products with transparent ingredient reporting and environmentally preferable chemistry.
  

• MRc4: Construction and Demolition Waste Management

  Even when stained with our chemical-free finishes, thermally modified wood is recyclable and reusable, helping reduce landfill waste.
  

• SSc7.1: Heat Island Effect Reduction – Non-Roof

  Used in exterior applications like decking or cladding, thermally modified wood helps lower heat absorption compared to conventional materials.
  

• EQc2: Enhanced Indoor Air Quality Strategies

  Safe for interior applications due to its low- or zero-VOC finishes and absence of chemical treatment.

  
  

• Innovation in Design (ID) Points

  Projects may qualify for innovation credits by using advanced, sustainable materials like thermally modified wood in unique ways.

In Short Choosing thermally modified wood isn’t just about selecting a high-performance material—it’s about making a responsible, forward-thinking choice that aligns with LEED principles and paves the way for a greener future.
