The development of effective protecting structures is currently one of the most popular areas in the construction industry. In order to ensure energy efficiency and environmental safety in the construction of civil buildings, masonry made of aerated concrete blocks with high thermal protection properties is used as protecting structures. As glue and cement-sand solutions in masonry have low thermal conductivity and are temperature bridges, the issue of filling through seams of aerated concrete masonry is very acute. The authors have developed a double row of concrete masonry, having a minimum number of cross-cutting horizontal seams, which not only improves thermal insulation properties, but also reduces material consumption and, consequently, the complexity of the arrangement of protecting structures of civil buildings. The influence of through horizontal seams made of cement-sand grout and block binding on the resistance to heat transfer of masonry made of aerated concrete blocks is considered.

The development of effective protecting structures is currently one of the most popular areas in the construction industry. Masonry made of aerated concrete blocks is used in conditions of ensuring energy efficiency and environmental safety in the construction of civil buildings as enclosing structures. It has high thermal protection properties. The issue of filling through seams of aerated concrete masonry is acute, since adhesive and cement-sand mortars in masonry have low thermal conductivity and are temperature bridges. The authors have developed a two-row energy-efficient wall masonry made of aerated concrete blocks using polyurethane glue as a filler for through and dressing joints. The article discusses the effect of horizontal through joints made of cement-sand mortar and blocking of blocks on the resistance to heat transfer of masonry from aerated concrete blocks. In addition, it presents a study of the reduced resistance to heat transfer of the enclosing structure, taking into account heat-conducting inclusions, presented in the form of a traditional two-row aerated concrete masonry through a row, made on a thin-layer adhesive solution, as well as the masonry developed by the authors. It is concluded that the energy efficiency of the developed wall fencing is ensured due to the increased thermal homogeneity of the masonry.
