IRUKA
Texture variation: Tactile
Responsibly sourced from US Cypress, IRUKA brings a charred wood surface to exterior and interior applications with a strong sense of natural grain beneath the finish. Its darkened face gives the boards a balanced, handcrafted presence, while the Cypress grain adds movement and warmth through the char. IRUKA is best for projects where the design calls for charred wood quality in a stable climate setting.

Cypress
Cypress is a naturally durable North American hardwood renowned for its resistance to rot, moisture, and insects — properties derived from cypressene, an oil native to the wood itself. Its straight grain and warm, honey-toned character make it a versatile choice for both interior and exterior applications. Cypress performs reliably across a range of climates, offering long-term durability with minimal maintenance.
