Increasing the thermal resistance of masonry wall systems is one of the effective ways to reduce energy consumption in the operation of masonry buildings. This increase is also demanded by newer, more stringent energy codes. However, the effective thermal resistance (R-value) of masonry walls is affected by many factors, such as thermal bridging, which occurs in places where highly conductive structural components penetrate insulating materials. Thermal bridging is common when connecting masonry veneers to structural backup walls. Furthermore, quick and precise methods for estimating the R-value are needed for thermal design improvements and code-compliance calculations. This study presents a comprehensive literature review on key factors that influence the overall thermal performance of masonry walls, methods to effectively estimate and measure R-values, and improvements in thermal design. In addition to identifying the main technical and practical challenges and the corresponding progress made on each front, key design considerations, such as code compliance, material properties, insulation types, and location, as well as special ties and shelf angles types, are also discussed. This study summarizes critical information and recommendations that will help improve the thermal design of masonry walls, hence reducing the energy consumption of buildings.

砌体墙的热阻:影响因素,评估和改进的文献综述

增加砌体墙系统的热阻是减少砌体建筑物运行中能耗的有效方法之一。新的,更严格的能源法规也要求增加这种能耗。但是,砌体墙的有效热阻(R值)受许多因素的影响,例如热桥接,这种情况发生在高导电性结构部件穿透绝缘材料的地方。将砖石饰面连接到结构支撑墙时,热桥接很常见。此外,快速准确的估算R的方法散热设计改进和代码符合性计算需要使用-value。这项研究针对影响砌体墙整体热性能的关键因素,有效估算和测量R值的方法以及热设计方面的改进提供了全面的文献综述。除了确定主要的技术和实践挑战以及在各个方面取得的相应进展之外,还讨论了关键的设计注意事项,例如规范合规性,材料特性,绝缘类型和位置以及特殊的系带和搁板角度类型。 。这项研究总结了重要的信息和建议,这些信息和建议将有助于改善砌体墙的热设计,从而减少建筑物的能耗。
