U-Value Calculations

To meet Building Regulations Part ‘L’

The U-value represents the thermal conductance of a given structure, for example an entire roof. The lower the U-value achieved – the better the level of insulation.

The R-value represents the thermal resistance of a given component within the structure, for example an insulation product. The higher the R value rating – the better the product.

Below are just a few examples of how different U-values can be achieved, we have many more on file and U-value calculations can be done for any specific type of construction.

SuperFOIL “Duet” Solutions

“Duet” solutions are a combination of two or more layers of SuperFOIL products over or under the rafters to achieve specific U-values.

Below, you will find a grid containing U-values, just click on a U-value to go directly to a U-value calculation prepared by a certified SAP assessor which can be used in building control application.
