Thermal Transmittance (U-Value) From Thermal Resistance Calculator

Note:

Thermal Transmittance (U-Value) represents the rate of heat transfer through a material or barrier. It is the reciprocal of thermal resistance and is expressed in W/m²°C.

Typical Input Ranges for Thermal Resistance (R):

*For best results, ensure R is within the range of 0.1 to 10 m²°C/W.
