EnergySimulatorCalculate your saving

The Rationel EnergySimulator will give you a good indication of how much you can save on your heating bill by changing your old windows and doors.

The process is quite simple. Put in the size of your house (in m2), when were your existing windows installed (four digits - i.e. 1978) and select which Rationel product you are interested in.
