Cross-Laminated Timber

Welcome to the Maniwa Visitor Center Pavilion, designed by renowned architect Kengo Kuma and crafted from locally grown timber. While the pavilion presents a strikingly modern silhouette, it also draws on centuries-old Japanese architectural traditions of using natural materials and blurring the lines between indoor and outdoor spaces.

The diamond-shaped wooden panels are made from an innovative building material called CLT (cross-laminated timber), created by laminating layers of sawn boards perpendicular to one another to form large panels. The resulting product retains the timeless beauty of wood while providing increased stability, heat resistance, and versatility. The panels also have a lighter environmental footprint than concrete or steel because they are made from a lightweight, renewable resource.

CLT allows for extremely efficient use of Maniwa’s local timber by enabling smaller pieces of wood to be amalgamated into large panels. It also creates a market for types of wood that are considered less desirable. A CLT panel crafted with hinoki cypress on the outside and cedar within retains the outward appearance of costly cypress while using cost-saving cedar where it will not be seen.

On the construction site, buildings using prefabricated, custom-made CLT can begin assembly immediately, with no need to wait for concrete to dry. The panels’ modular nature means these structures can also be easily disassembled and moved. In fact, this pavilion spent its first year in Tokyo, where it was used as an exhibit promoting the use of CLT. It was then dismantled, shipped, and reconstructed here in March of 2021.

CLT直交集成板

歡迎來到「風之葉」！這個位於「綠色蒜山」（GREENable HIRUZEN）內的著名地標由知名建築師隈研吾設計，使用當地木料精心打造。在它引人注目的現代外表下，蘊含著沿襲了千百年的日本建築傳統：選用天然材料，模糊室內外空間界限。

這些菱形大木板是一種被稱為直交集成板（CLT）的新型建材，由多層原木薄板以木紋垂直相交的方式疊加膠合而成。CLT產品保留了木材恒久之美，同時更穩定、絕緣耐熱、多用途。由於採用了輕質的可再生資源，它對環境的影響比混凝土或鋼材更小。

通過將碎小木材拼合成大型板材，CLT最大化地實現了對真庭當地原木材料的利用，同時又為品級稍低的木材打開了市場。通常，CLT表層使用昂貴的日本扁柏，內部則採用相對低廉的日本柳杉，兼顧了外觀與成本。

CLT可以在建築現場直接使用預製零件組裝，無需像混凝土那樣等待乾燥。得益於板材的模組化特性，它們同樣易於拆除和搬遷。比如「風之葉」，第一年就是作為CLT的展示品在東京度過的，之後於2021年3月運到這裡重新搭建。
