Caring for natural resources is one of the most important components of the sustainable development of the
 national economy of the Russian Federation. This is facilitated by the use of low-grade wood, including fire-damaged
 wood, as a structural material, which will reduce the cost of producing laminated wood structures (GWB) through the use
 of cheaper raw materials. Based on a systematic analysis of sources and our own empirical research, the features of a new
 technology for manufacturing laminated wood beams with a span of 6.0 m using wood damaged by fire from a forest fire
 are presented. This study is aimed at reducing the material intensity of laminated timber structures through the partial use
 of low-grade wood without reducing the load-bearing capacity of the beams. It was found that when replacing 36% of the
 middle lamellas in the cross-section with thermally damaged wood, the reduction in the load-bearing capacity of the beam
 structure relative to a beam made entirely of grade I wood was 9.7%, and when replacing 62% of the wood – 16.06%.
 The use of thermally damaged wood in the manufacture of laminated wood structures will significantly reduce the use of
 high-grade lumber with some changes in the technological process that do not lead to an increase in its cost. Using the
 positive experience of testing beam FDCs, it is planned to further study the use of thermally damaged wood in compression-bending structures.
