EPD might not be comparable if different functional unit or reference thickness is used.Declared unitThis EPD describes the environmental effect of 1m3 of plywood board throughout the life cycle.The density of the plywood board is 480 kg/m3.System boundariesCradle-to-Gate with options;product stage (A1-A3), - construction process stage (A4-A5), - use stage (B1-B7), - end-of-life stage (C1-C4).Cut-off rulesIn the inventory of the input flows a 1 % cut-off rule has been applied. The 1 % cut-off rule is based on the assumption that these input flows do not have a major impact on the environmental impacts as a whole (EN 15805 6.3.5).
