Side-by-side comparison of the declared technical data for X-LAM (CLT) and Glued Laminated Timber (GLT). Rows are aligned by metric: the properties both sheets share come first, then the rest. Values come from Architheca material sheets; where a material has no datum you’ll see “—”.

Rows aligned by canonical metric; each material’s original label is shown when it differs from the metric name. Declared sheet data — not a substitute for product certifications.
