加拿大住宅和建筑的国家能源标准规范范本中规定了外壳组件（包括钢钉墙）的最低热特性。为了帮助统一执行这些要求，规范有必要规定计算钢螺柱组件热阻的可接受方法。ASHRAE手册基本原理提出了一种预测螺柱墙热性能的简单方法，该方法基于等温平面和平行路径计算方法预测值的加权平均值。 2440mm×2440mm（8ft×8ft）墙体试样的热阻为92mm（35/8in.）在一系列防护热箱试验中测量了钢制螺柱。评估了两个螺柱量规以及两个螺柱间距，其中一个为木质，三个为绝缘护套。测量结果表明，权重为2:1（等温平面:平行路径）可以准确预测406 mm（16 in.）处带钢钉墙体的热阻o、 c.，但1:1的权重最好地预测了610 mm（24 in.）钢钉墙体的热阻。 )o.c.这些结果适用于直接应用于螺柱的木质护套的墙壁，无论墙壁是否有绝缘护套。最后，测量结果表明，3:2的中间权重最能预测直接安装在螺柱上的绝缘护套（即没有中间结构护套）墙体的热阻。单位:双引证:研讨会，ASHRAE交易，1998年，第104卷，第2部分，多伦多

Canada's Model National Energy Codes for Houses and for Buildings contain prescriptive requirements in the form of minimum thermal characteristics of envelope assemblies, including steel stud walls. To assist in the uniform enforcement of these requirements, it was necessary for the codes to prescribe acceptable methods of calculating the thermal resistance of steel stud assemblies. The ASHRAE Handbook-Fundamentals proposes a simple method for predicting the thermal performance of stud walls, which is based on a weighted average of the values predicted by isothermal planes and parallel path calculation methods.The thermal resistance of 2440 mm × 2440 mm (8 ft × 8 ft) wall specimens, with 92 mm (3 5/8 in.) steel studs, was measured in a series of guarded hot box tests. Two stud gauges were evaluated, as well as two stud spacings, with one wood-based and three insulating sheathings. The measurements demonstrated that a weighting of 2:1 (isothermal planes:parallel path) provided an accurate prediction of the thermal resistance of walls with steel studs at 406 mm (16 in.) o.c., but that a 1:1 weighting best predicted the thermal resistance of walls with steel studs at 610 mm (24 in.) o.c. These results applied to walls with wood-based sheathing directly applied to the studs, whether or not the walls had insulating sheathing. Finally, the measurements demonstrated that an intermediate weighting of 3:2 best predicted the thermal resistance of walls with insulating sheathing installed directly onto the studs, i.e., without intermediate structural sheathing.Units: Dual
