At Excelsior Wood Products, we’re always looking for ways to bring high-performance, design-forward materials to our customers. That’s why we’re excited to introduce Inari™—a thermally modified spruce that delivers durability, versatility, and natural beauty for exterior applications. Whether you’re designing siding, decking, or custom profiles, Inari™ offers a reliable solution that doesn’t compromise on aesthetics or cost.

What is Inari™?

Inari™ is a thermally modified spruce sourced from Europe and available exclusively through Excelsior Wood Products. Known for its clean grain and natural appearance, this wood stands out because it looks exactly like what it is—authentic, real wood. Through the process of thermal modification, its inherent durability is enhanced, making it a product that performs exceptionally well in exterior applications.

Inari™ is also harder than many alternatives, allowing it to hold fasteners better than traditional woods. Combined with our ability to custom mill, it’s a flexible option for a wide range of projects.

Built for Exterior Performance

Inari™ shines in exterior applications. It’s especially suited for:

• Siding: Clean, modern profiles or traditional patterns with long-term stability
• Decking: Durable surfaces that stand up to the elements
• Custom exterior millwork: Tailored solutions for unique builds

Its strength and resistance to expansion make it ideal for climates with fluctuating moisture, which helps it maintain both structural integrity and visual appeal throughout time.

The Power of Thermal Modification

What strengthens Inari™ is the thermal modification process. By applying high heat and steam in a controlled environment, the wood’s cell structure is permanently altered. This reduces moisture absorption and significantly improves resistance to rot, insects, and decay.

The result is a more stable product that won’t expand and contract like untreated wood, making it a dependable choice for outdoor use. The process also enhances the wood’s natural color, which is integral to Inari’s™ rich, refined tone.

Why Choose Inari™?

Inari™ combines performance, beauty, and value in a way few woods can match. It’s durable, easy to work with, customizable, and competitively priced, so it’s an excellent alternative to more expensive or less resilient options.

Excelsior is proud to be the exclusive source for Inari™ wood. From sourcing to milling, we ensure every board meets our standards for quality and consistency.
