In the context of construction, the R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive flow of heat. R-value is the temperature difference per unit of heat flux needed to sustain one unit of heat flux between the … Se mer This relates to the technical/constructional value. $${\displaystyle R_{\text{val}}={\frac {\Delta T}{\phi _{q}}}}$$ where: • Se mer Note that the R-value is the building industry term for what is in other contexts called "thermal resistance" "for a unit area." It is sometimes denoted RSI-value if the SI (metric) units are used. An R-value can be given for a material (e.g. for Se mer The SI (metric) unit of R-value is kelvin square-metre per watt (K⋅m /W or, equally, °C⋅m /W), whereas the I-P (inch … Se mer The Australian Government explains that the required total R-values for the building fabric vary depending on climate zone.
