CLT (Cross Laminated Timber)

Product information

CLT by Stora Enso is a solid wood construction product consisting of several (3, 5, 7, or 8) bonded single-layer panels arranged at right angles to each other. The layers are bonded with carefully selected adhesives that are suitable for the respective purpose. CLT products are long-lasting and safe to use and recyclable. They are continuously tested to ensure that they meet the strictest requirements in terms of ambient air emissions. CLT also offers virtually boundless possibilities in terms of construction concept, style and architecture.

Lightweight yet strong, with superior acoustic, fire, seismic, and thermal performance, CLT is currently being used in place of concrete, masonry and steel in the construction of residential, industrial and commercial buildings. Thanks to its inherent structural qualities, CLT presents no limitations to architecture. CLT resists high racking and compressive forces, so it can be especially cost-effective for multi-storey and long-span applications. Because of its dimensional stability and structural properties, this massive wooden product is well suited for floors, walls and roofs. CLT is a highly flexible wood product that is easily tailored for further processing. It can be used together with any building material. And compared with heavy mineral-based materials, CLT is easily moved by lighter cranes at the construction site. 

CLT is a renewable alternative to traditional construction materials that can have large environmental footprints. As trees grow – and when they are used as timber in buildings – they efficiently store carbon.
