Substantiated is the expediency of estimating the amount of wood waste in the manufacture of window units from three-layer glued bar. The methods of experimental studies for estimation of the amount of waste at all stages of the production process are developed. Step-by-step wood consumption coefficients are determined per 1m3 of rectangular cross-section blanks for window units made from three-layer glued bars with a cross-section of 68×78mm. Determined is the percentage of wood chip waste of the volume of a blank part for a tenon or mortice, and the percentage of wood chip waste at the stage of profiling of the blanks from the three-layer glued bar. The obtained results will allow estimating the amount of wood waste in the production of window units from three-layer glued bars with double-glazed windows of various sizes and structures.
