* By improving thermal insulation (regardless of the external building component to which it is applied) the heat flow from the inside to the outside is reduced. | * By improving thermal insulation (regardless of the external building component to which it is applied) the heat flow from the inside to the outside is reduced. | ||

* Therefore the heat flow from the building’s interior to the internal surface of this external building component is also reduced. The heat flow overcomes the so-called thermal resistance of the surface (radiation and convection). | * Therefore the heat flow from the building’s interior to the internal surface of this external building component is also reduced.

* The smaller heat flow results in a smaller temperature loss at this surface, in other words: //the temperature difference between the inside (the surfaces in the room and the indoor air) and the interior surface of the component with improved insulation decreases.// | * The smaller heat flow results in a smaller temperature loss at this surface, in other words: //the temperature difference between the inside (the surfaces in the room and the indoor air) and the interior surface of the component with improved insulation decreases.// | ||
