Brickwork thermal conductivity

WebA general rule is that mortar joints can be treated as having insignificant influence [2] when the thermal conductivity of the masonry units is greater than 0.5 W/mK. If the concrete blockwork layer is examined the light concrete block R = 0.100/0.20 = 0.500 m 2 K/W and the protected mortar R = 0.100/0.88 = 0.114 m 2 K/W. WebJan 8, 2024 · The thermal conductivity of refractory bricks, that is, their ability to transfer heat, is usually expressed in terms of thermal conductivity. Thermal conductivity refers to the amount of heat passed per unit area in unit time and unit temperature gradient in the process of energy transfer.
