====== Thermal protection works ======

How come there is any doubt at all that this obvious statement is true?\\ 
Whatever scepticism there may be, the following article compiles evidence that is beyond doubt:
    * Insulation works, especially insulation of buildings and exterior building walls.

    * It works exactly according to the findings of building physics that have been proven true for many decades.

    * Insulation offers the greatest potential for energy savings for the foreseeable future.

    * Better thermal insulation doesn’t only save energy but also helps avoid structural damage and increase comfort. 

    * Better thermal insulation also pays off in purely financial terms: The savings in energy costs more than make up for the extra cost for the insulation.\\

These statements have been proven by practical experience with highly insulated new buildings as well as older buildings retrofitted with heat insulation. In all cases, this evidence is based on accurate scientific methods. The measurement results are so clear that they can be understood by anyone and they correspond exactly with the state of knowledge in building physics, the scientific discipline dealing with such matters. The following articles illustrates practical examples that provide comprehensible evidence for the effectiveness of thermal insulation – and that have already been presented in scientific publications.\\
