Durable wood exterior wall that resists decay. Redwood siding type [Sample available].

Exterior wall material of "Redwood." A natural material with ultra-high durability that surpasses red cedar, free from chemicals, designed to be inherited for generations to come.

The redwood, known as Sequoiadendron giganteum, which grows wild in California, is a rare wood that, despite being a conifer, possesses one of the highest levels of resistance to decay among timber. In the wild forests, it can exceed heights of 100 meters, and due to its unique ecology, it is a species that has succeeded in survival competition. However, its population has drastically decreased due to rampant logging during the Gold Rush era. Currently, a small, stable, and long-term industrial use has been realized from individuals that are strictly managed in plantations. Redwood has been cherished by various architects, including Charles Moore, and has woven its history. This exterior wall material, processed with a rough surface in California, is resilient to Japan's climate changes due to its increased adaptability to shrinkage, and it also has good paint adhesion. Thanks to its characteristic of growing straight and large, it has been commercialized in standard sizes. While there are variations in color, the lumber produced is close to being knot-free.
