Windows & Doors Energy Saving Simulator

We are pleased to announce the launching of a new tool that will help you calculate potential energy savings on an annual basis. For older houses we have seen significant savings using modern composite windows and doors. The energy saving simulator 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.

This online tool is an excellent way to try before you buy your composite windows and doors. For more information please contact Ecotec Windows on 01226 702566 for an informal discussion on our window and door range.
