If you have been checking recent timber-based construction projects, then you have probably come upon this acronym a few times: ?CLT?. These three letters stand for ?Cross Laminated Timber? which is an engineered-wood product that promises to take wood-based construction to a whole new level. Cross-laminated timber first emerged in Europe, and then it gained popularity in the US and other locations. The material has proved efficient for use in various building typologies, ranging from low to high-rises. Furthermore, it has shown competency in the matters of strength, speed, and cost, compared to both concrete and steel. However, the CLT?s main attraction lies in the fact that it is a sustainable construction material, and that, most of all, gives it an edge above other reliable construction materials. So, here we try to answer all your questions about this material, on the rise and tell you what you need to know. Who invented cross-laminated timber"
Cross-laminated timber first made an appearance in Europe, particularly in Austria and Germany, in the early 1990s. Then, in the mid-1990s, a joint research was conducted in Austria and resulted in the production of CLT in its modern form.
