Cross-Laminated Timber (CLT) - Reference Design Values

Mass-timber CLT panels - PRG 320 grades (E1-E4, V1-V3) and EN 16351 layups. Panel capacity depends on the specific layup; the values shown are the lamination basis - use panel tables or the shear-analogy method for design. All values are to ANSI/APA PRG 320 / EN 16351, shown before adjustment factors.
