Apr 6, 2017 · Whereas the lower the U-Value, the more energy efficient the material is. This calculator makes it easy to convert between R and U Values. The U-value is the reciprocal of the R-value; that is U = 1/R and R = 1/U. Calculates the R or U Value for multiple materials combined. Work out for a wall or ceiling how much heat is being lost through it.

A U-value (also known as thermal transmittance) measures how well a construction, such as a wall, roof or floor, can resist heat loss (primarily from heat conduction). This is given in units of W/m2K. The lower the U-value, the better insulated a construction is. By using materials which are less conductive to heat (have a lower thermal ...
