The article is devoted to the actual problem of restoration of construction objects of Ukraine destroyed as a result of military actions. The issue of manufacturing and effective application of cross-laminated timber panels and other products made of laminated timber for use in recon-struction, restoration of damaged construction objects and new construction is considered. Why can the availability of the raw material base, its renewability and ease of extraction and processing contribute. Cross-laminated timber is a relatively new building material based on timber, which is an array of boards laminated in layers in a mutually perpendicular direction. The layers of lumber are laminated together under pressure, forming a virtually monolithic slab. The production of cross-laminated timber solves one of the important problems, namely the use of small and medium-sized cross-sections of boards to create large arrays, which allows you to signifi-cantly save commercial timber. The main advantages of laminated and cross-laminated timber as building materials are given and the feasibility of their application for buildings and structures of various functional purposes is proven. Examples of modern high-rise buildings con-structed using cross-laminated timber panels around the world are presented. Due to the elimination of some of the defects of whole timber and the preservation of one of the main advantages, namely, low weight with relatively high strength values, laminated and cross-laminated timber can become one of the main materials for the development of new areas and the restoration or reconstruction of damaged ones as a re-sult of military actions, buildings and structures of various purposes. The low weight of structures made of laminated and cross-laminated timber will reduce the cost of strengthening existing structures and the cost of ma-terials for new foundations in the case of new con-struction by at least 30% in comparison with houses erected using more traditional methods - these materials.
