TerraMai Modified Hardwood OpenSpan Panels are designed to define interiors without closing them off. Constructed from sustainably harvested hardwoods in the Eastern United States, these panels undergo a thermal modification process using only heat and steam. The result is wood that is dimensionally stable, highly durable, and resistant to movement, moisture, and decay.

Each panel is designed to span floor to ceiling with no mid-rail interruptions, providing unbroken sightlines and a clean, modern look. This stability allows the slats to be supported only at the top and bottom, creating openness while maintaining structure.

Our natural finish highlights the grain and tone of the hardwood, offering warmth, depth, and authenticity. Available in standard 8’ and 10’ heights with custom options also offered, Modified Hardwood OpenSpan Panels are ideal for architects and designers seeking a sustainable, high-performance solution that balances beauty with function.
