Abstract
CLT – material for the measure of the future. CLT (cross laminated timber, X-Lam) is one type of engineered wood products. The first idea of CLT was presented in the seventies of the last century in Austria. Over the following years, the concept of cross-gluing wood was intensively developer in Europa, USA, Canada and China. Based on the literature data, this work presents history, structure, production process ,selected mechanical and physical parameters and applications of CLT. CLT is a wood panel product made from gluing together layers of solid-sawn lumber. The number of wooden layers is unpaired, most often 3, 5 or 7. Each layer consists of closely spaced and parallel boards. Adjacent layers are perpendicular to each other. The physical and mechanical properties of this product depend on many factors, e.g. number of layers and their thickness, the width and thickness of the boards in the layer, class of lumber, species of wood. Despite the fact that CLT is rather new material often used, especially in construction industry (both single-storey and multi-storey buildings). The short time of project implementation and their ecological character indicate that CLT is the material of the future in construction industry.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
