I understand that thermal conductivity is W/(m.K) and u-factor is W/m² K. Obviously U factor is energy transfer over an area but how does this compare to thermal conductivity?

Futsal1st said:So is thermal conductivity multipied by the area of the surface the U Factor (or close as damn to it)?
Futsal1st said:So is it divide by a unit depth (I assume 1000mm) and multiply by area?
Thermal conductivity is a measure of how well a material conducts heat, while U factor is a measure of how well a material insulates against heat transfer. In other words, thermal conductivity measures the rate of heat transfer through a material, while U factor measures the resistance to heat transfer.
No, thermal conductivity and R-value are not the same. R-value measures the thermal resistance of a material, while thermal conductivity measures the rate of heat transfer. A material with a high R-value has a low thermal conductivity, and vice versa.
Both thermal conductivity and U factor play important roles in determining a material's insulating properties. However, the U factor takes into account other factors such as the thickness and density of the material, making it a more accurate measure of a material's insulation capabilities.
Materials with low thermal conductivity and high U factor are more energy efficient, as they are better at insulating against heat transfer. This means that less energy is needed to maintain a comfortable temperature in a building, resulting in lower energy bills.
Yes, both thermal conductivity and U factor can be improved through the use of insulation materials. These materials have high R-values and low thermal conductivities, effectively reducing heat transfer and improving energy efficiency.
