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 ...
- U-values allow us to set clear targets for how well insulated constructions must be. This is crucial as we look to deliver more energy efficient bu...
- You can achieve lower U-values by using materials which have lower thermal conductivities (also known as lambda values). You can also increase the...
- A lower U-value means that the roof, wall or floor is better insulated and will be more effective at preventing heat loss. It is easier to achieve...
- This will depend on a number of factors which are specific to your project such as: whether it is a new or existing building; what level of energy...
- The thermal performance of insulation is measured using thermal conductivities (also known as lambda values). These measure how well a material con...
- U-value calculations measure how well insulated a construction is. They are primarily the sum of the thermal resistances of the layers that make up...
- To calculate a very basic U-value, you must first look at the individual materials which make up a construction. By dividing each material’s thickn...
