Floor insulation can also be done without using the heating system using the XPS boards together with cement and the final material. This will also lower the energy consumption of the whole structure. In this method, the concrete subfloor is covered with thick XPS insulation boards and then a thin layer of cement is applied on top. In the end, the final materials such as wood tiles are installed. This can be also used to renovate the old floors and buildings to make them energy efficient.
