The above range of windows and doors are compliant for both new builds / extensions and existing dwellings using the limiting values.
The notional values are also achievable for new builds. Please let us know whether you require your calculations to be based on the notional value or the limiting value.

Notional Values – these are used to calculate the Target Emission Rate of a particular building. Once this is calculated, elements of the building can be offset providing the overall Target Emission Rate is met.
The Limiting Values – are the maximum possible u values for each element of the build
WER = Window Energy Rating | DSER = Door Set Energy Rating
